Back-story….

Developing the Cumbria Botany website for individual taxon accounts and distribution maps arose from two considerations.
1: Geoffrey Halliday’s matchless account of the county’s vascular flora A Flora of Cumbria has passed its quarter-century! Published in 1997, it reports and records the state of the county’s flora based upon a survey carried out in the years 1974–1997, with detailed and illustrated introductory chapters by several authors on many aspects related to the county’s flora, and approaching 1800 species-accounts. A Flora of Cumbria is out-of-print – albeit available in the secondhand marketplace. These species-accounts have full relevance today, providing both historical context and cogent summaries of distribution, ecology, and much else. Online availability gives the potential for a wide new audience, and, we hope, longevity.
2: For Cumbrian recorders (after a couple of years of well-earned respite, post-1997!) the BSBI’s twenty-year cycle of recording, 2000–2019, usefully re-focussed efforts, and in the latter years of that round, a very large amount of re-recording was Cumbria’s contribution to the landmark publication in March 2023 of Plant Atlas 2020 – as a two-volume printed tome and also, with a slightly different set of parameters, online. Plant Atlas 2020 online offers mapping to tetrad (2×2km) scale, and much else besides, and is a hugely useful resource.
Enquiries with BSBI confirmed that we could request a complete download of the current set of mapping data for the county to monad (1×1km) scale, consisting of well over a million individual records. This brought the possibility of creating species-pages populated by: i) the up-to-date monad-scale map; ii) the accounts from the Flora; iii) comments updating the 1997 accounts where deemed necessary, or for species lacking Flora accounts, including additions to the county list since 1997; iv) illustrations of images taken within the county.

A great deal of work through 2023 and to date (April 2024) by the team from the Flora of Cumbria Recording Group initially decided on issues such as hosting, copyright, and generating interactive maps. (Initially an Advisory Group, there was a certain inevitability in its evolution via Steering to Working Group, as it remains!) There was then the large task of extracting the species-accounts from A Flora of Cumbria into digital format (as no digital version in any format was forthcoming). Some of the team have expended – and are expending – large amonts of time on the project, and I am very grateful for their persistence and commitment.
We are delighted to be able to work with Chris Cant (PHD Computer Consultants Ltd.) who has set up the mapping page, and whose coding generates the maps from BSBI mapping data. (This coding is a modification of that already in use in the maps in the ‘Resources’ sections of Cumbria Lichens and Bryophytes, and (since January 2024) interactive maps for the British Lichen Society.)

Brambles: Rubus subgenus Rubus

(i.e. Rubus caesius L. and Rubus fruticosus L. sensu lato – but note that all Cumbrian Rubus species are also included here, both the critical and non-critical species – Cloudberry, Raspberry, Stone Bramble, and so on.)

The mapping/accounts page is here

Species-accounts are those from A Flora of Cumbria (1997), for species which are covered therein. Updating comments may be added in due course.

Forty-one species were covered in A Flora of Cumbria; fifty-seven are currently recorded.
(For completeness the five Cumbrian non-bramble Rubus species are included in the menu.)



Introductory account and key, A Flora of Cumbria (1997)

This account and the accompanying maps are based chiefly on records made by GH from 1980 and contributions from A. Newton (AN, from 1972), E.S. Edees (ESE, 1954–1965) and C.W. Muirhead (1943–1972). The time span is therefore appreciably longer than the 20 years of the recording scheme, although of the 42 species recorded only Rubus bertramii and R. amplificatus have not been seen during the Survey. A number of recorders have also assisted with the collection of material, notably JA, AAD and MG, and the initial stimulus leading to the recent activity was provided by a collection from south Cumbria by A.J. Sherwood in 1980 and 1981. A significant result of these efforts is a large, modern, comprehensive collection of Cumbrian specimens in LANC. Almost all the Survey records, except those of the commoner species, have been checked by A. Newton. He has also seen most of C.W. Muirhead’s collection (CLE, PLYP).
Lack of space and uncertainties regarding identification and synonyms mean that references in this account to pre-1940 literature records and first vice-county records are largely omitted. Early herbarium records, accepted by ESE and AN, are cited where these supplement recent records. Few of the records in the three county Floras were made by the authors and the only early papers which make any significant contribution to our knowledge of Cumbrian brambles, particularly of the Lake District, are those of Ley & Linton (1906) and Rogers (1907).
Despite the daunting nature of attempting to record brambles on a tetrad basis, probably the first such vice-county survey, the often well defined and varied distributions suggest that there are probably few areas which are so under-recorded as to render the maps misleading, and further that distortions due to over-collecting along roadsides is of little significance. In fact woodlands and especially heaths, the characteristic habitats in southern England, are relatively unimportant in Cumbria where brambles are very much a feature of roadside verges, the edges of stone walls, waste ground and neglected pasture. An exception is the section Rubus, the species of which occur chiefly around lowland mosses and by becksides, particularly in the Lake District.
Brambles are essentially lowland, rarely being found over 250 m, and no single species is characteristic of higher altitudes. In the south-east of the county R. robiae ascends to 305 m in Garsdale and the coastal R. ulmifolius to 270 m, north-east of Sedbergh. In the east, R. dasyphyllus and R. latifolius reach 270 m at Alston and R. adenanthoides 475 m at Nenthead. while the garden R. armeniacus grows at 210 m at the M6 service station north of Tebay. Members of section Corylifolii are noticeably absent from the Lake District, a fact which makes brambling there distinctly pleasurable! Yet these are the only brambles present in the upland limestone area between Asby and Orton.
Although 40 species of brambles may seem quite a rich flora, and it is by northern standards, it is nevertheless paltry compared with that of southern English counties. This relative paucity does however ease the task for beginners and it is hoped that the following key and the brief diagnostic notes will assist them in becoming acquainted with the species. Care is of course necessary. Material from extremes of shade or exposure should be avoided. Well-developed mature leaves and stem from new vegetative shoots and a terminal flowering panicle of a shoot of the previous year are usually both necessary. It is also important to note the colour of newly opened flowers. A particular problem is the frequency with which species intermingle making it only too easy unwittingly to collect vegetative and flowering material of different species.
This account follows the sequence and nomenclature of Edees & Newton (1988), the species being arranged alphabetically within the relevant groups. It must be stressed that within subsection Hiemales the series represent artificial divisions of a spectrum of variation and they are not therefore as precise as one would like. The following names used in earlier Floras differ from those used by Edees & Newton.
R. affinis (= mostly R. nemoralis); R. bellardii (=?); R. carpinifolius(= mostly R. polyanthemus and R. errabundus); R. corylifolius var. conjungens (= R. latifolius) var. sublustris (= R. pruinosus); R. discolor (= R. ulmifolius); R. drejeri (= R. anisacanthos); R. dumetorum var. diversifolius (= R. tuberculatus) R. fissus (= R. scissus); R. fuscus (=?); R. hirtifolius var. danicus (=?); R. hystrix (= R. hylocharis); R. incurvatus (= R. incurvatiformis); R. koelerisubsp. dasyphyllus (= R. dasyphyllus) ; var. infestus (= R. infestus); var. pallidus (= R. dasyphyllus); R. leucostachys (= R. vestitus); R. maasii (= R. polyanthemus); R. macrophyllus (=?); R. mercicus var. bracteatus (= R. cumbrensis); R. opacus (unnamed Langdale plant); R. pyramidalis (= R. incurvatiformis); R. radula var. echinatoides (= R. echinatoides); R. rhamnifolius (= R. errabundus and R. furnarius) var. cordifolius (=?); R. rogersii (= R. fissus); R. rosaceus (= R. hylocharis); R. rudis (= R. echinatoides); R. rusticanus (= R. ulmifolius); R. salteri (= R. errabundus); R. scheutzii (= R. errabundus); R. selmeri (= R. nemoralis); R. suberectus (= R. nessensis); R. umbrosus (= R. polyanthemus); R. villicaulis (= R. nemoralis)

The following species occur in neighbouring vice-counties but as yet have not been found in Cumbria.
R. rubritinctus [NB: found in Kendal area, 2002–4, A.M. Boucher] and R. sprengelii (v.c.60, W. Lancs.), although Baker cites an unsubstantiated record from Storrs, Windermere (3.9).
R. hebridensis and R. lanaticaulis (v.c.71, Isle of Man)
R. leptothyrsos (v.c.72, Dumfriess.)
R. scotticus (v.c.73, Kirkcudbrights.)

Cotoneasters ~ Cotoneaster

The mapping/accounts page is here.

Species-accounts are those from A Flora of Cumbria (1997), for species which are covered therein. Updating comments may be added in due course.

Stace (Ed. 4, 2019) describes, and keys out, ninety-three (!) species of Cotoneaster in Britain and Ireland. The Plant Crib has a useful key (1997; ‘minor update 2012’) by J. Fryer to the ‘twenty most likely species to be found in Britain’.
Tim Rich’s recent publication Identification Guide to British Schedule 9 Cotoneasters is available at cost in Kindle format. It covers the five ‘Schedule 9’ species (invasive plants under the Wildlife and Countryside Act 1981), bullatus, simonsii, horizontalis, integrifolius and microphyllus), with notes separating them from other closely related species.

Twelve species are mentioned in A Flora of Cumbria. The current county list stands at twenty-eight species and two hybrids… a somewhat alarming increase in twenty-seven years!



Introductory account and key, A Flora of Cumbria (1997)

Although there is only a single record in the early Floras, this genus is now known to be represented in the county by at least twelve species. Probably all but one have appeared during the last 50 years, becoming naturalised from garden throw-outs or by bird-dispersal from gardens, although plantings, especially in the Arnside area, cannot be excluded. With the exception of the three commonest species, Cotoneaster horizontalis, C. integrifolius and C. simonsii, all records have been checked by J. Fryer.
The following key is based on information which she has provided. [NB. A further species, C. rotundifolius Wallich ex Lindley, not keyed below, is listed in the Addenda page with the following information: Found by the roadside south of Uldale in 1995 (22.54, MP, 1995, det. J. Fryer). This species differs from Cotoneaster microphyllus in being more erect (-2 m) and having generally longer leaves (-2 cm) and larger flowers (1-1.3 cm across), which are always solitary.]

1. Lvs 0.5-1.5 cm
  2. Lvs sub-orbicular; petals pink; branches herringbone: > C. horizontalis
  2. Lvs obovate-elliptic; petals white: > C. integrifolius
1. Lvs more than 1.5 cm, at least twice as long as wide
  3. Lvs bullate, to 15 cm long
   4. Fruits black
    5. Lvs strongly bullate: > C. moupinensis
    5. Lvs not strongly bullate: > C. villosulus
   4. Fruits red
    6. Lvs to 7 cm, petioles 3-6 mm; calyx hairy: > C. bullatus

Introductory account and key, A Flora of Cumbria (1997)

[Reproduced with permission]
“[This account is substantially that prepared by Chris Haworth in 1989 shortly before his untimely death. It has been revised by Andrew Dudman to incorporate subsequent records and recent taxonomic work (Dudman & Richards 1997).]

The genus Taraxacum poses considerable problems for the Flora writer. Like Hieracium and Rubus, this largely apomictic group abounds in species (microspecies), about 250 being currently recognised in the British Isles. This fact alone creates obvious problems of coverage as well as of identification. Dandelions are, however, even commoner and more widespread than hawkweeds or brambles, and the weedy nature of many species in some of the sections compounds the recording problem. Yet this very abundance demands some serious treatment in a Flora.
However, there are further difficulties, which have led to the genus still being by far the least understood of the ‘difficult’ genera that are represented in these islands. It seems worth outlining why. Firstly, in contrast to the intensive attention that most of our flora has received for a hundred years and more, Taraxacum has been strangely neglected. British botanists were reluctant (some still are!), despite the obvious genetic variation of these ubiquitous plants, to accept the special taxonomic problems present. The treatment in the Atlas of the British Flora (Critical Supplement) (Perring & Sell 1968), for example, actually impeded progress. Secondly, the material is not ‘easy’: the collecting season is short and only practicable during the spring flush from mid-March (in sheltered lowland places) to the end of June (in the uplands), collecting and herbarium preparation must be done with great care, and there is a daunting phenotypic plasticity. Thirdly, there appear to be many rare species (including some yet unpublished). Many are doubtless local endemics, but, with over 2000 species worldwide, there is a large pool of potential casuals, especially in section Ruderalia. These rarities cloud the identification process. Reflecting these difficulties is the fact that Richards’s (1972) Taraxacum Flora dealt with only about half the species now known in Britain. Nevertheless, A.J. Richards and I now agree that there are about 100 ‘important’ species in Great Britain, i.e. those that are common, at least regionally, and are well understood taxonomically. Many of these have been recorded in Cumbria.
All these factors, then, have influenced the treatment here. Fig. 19 indicates the number of species recorded in each 10 km square. Clearly the cover is inadequate and uneven. No records from v.c.65 (N.W. Yorkshire) are included and only some squares in west Cumbria can claim to approach a representative coverage. What the map does suggest, however, is that one might expect the average number of species per square to be about 50. The total number of species in this account is 123, and this accords with the picture for other well-studied areas.
It is inevitable that there will be some errors of omission and commission with such a fluid and complex genus. Nevertheless, the writer is convinced that this report represents a fairly accurate picture of Cumbrian dandelions. It is unlikely that any significant species has been overlooked. Further work could doubtless change the picture for some of the apparently uncommon species and there will always be problems of misidentification and misinterpretation. The author has made the majority of records (many in the field) and determinations; most of the other records are those of A.J. Richards and A.A. Dudman. Collections of modest size have been made by a number of Survey workers. These contributions have been included here and the author is grateful for these efforts. Species with more than ten 10 km square records are mapped. Representative material is in OXF and LANC.
Regarding the Sections, it should be understood that, of their nature, the concept is ‘multidimensional’. In other words, anyone using the keys should use as many characteristics as possible. Ecological ones are given more weight than is perhaps usual. It should be noted that some species occur at the boundaries of sections. This underlies the somewhat arbitrary nature of sections, which are meant to reduce the genus to more manageable groups, as well as to engender taxonomic meaning.
Maybe these finer points will not concern the average Flora user, but are made both to underline the relative youth of British Taraxacology, and perhaps more importantly, to act as a stimulus to encourage botanists to meet the many challenges yet to be encountered in this, the last major frontier of British floristic botany.
The task of constructing keys to the species has, so far, proved beyond the author’s skill and energies! Attempts to use the familiar and simple, one-character dichotomous keys provided by workers in other large and critical genera have convinced him of the limitations to such keys. One might suggest that they are at best often misleading, and at worst mischievous, where they can give the average botanist what may be false concepts, which may then prove difficult to eradicate. To be more positive, however, most of the following accounts include a description of some distinguishing features of each species. Most attention has been given to those species which the author feels warrant this. At the end of the day, if the student admits that there is something that can be said beyond ‘hic sunt dentes leonis, the writer will be gratified!
Finally, a few acknowledgments: Without the constantly stimulating encouragement over the years from my co-worker John Richards, on whose shoulders all British taraxacologists stand, most of the advances evinced below would never have occurred. My friend Andrew Dudman has been ever supportive in ways too numerous to mention, both in the field and in particular with the production of this account. My wife Bertha has proved to be a patient word-processor in the face of outrageous demands and changes of mind. In addition, without her domestic succour through some difficult times, the account would never have appeared. Words, being inadequate for thanks, the following account will, I trust, suffice instead. I lay a firm claim to the errors of all types which certainly remain.

Comments on Sections (A Flora of Cumbria, 1997)

Section 1. Erythrosperma: This largely native section is well represented in Cumbria. The main characteristics and habitats are indicated in the above key.

Section 2. Obliqua: This section has few species and is seemingly very discrete and natural. The species have a superficial resemblance to section Erythrosperma but the leaves have a different texture and the achenes are very different.

Section 3. Palustria: There are only a handful of British species in this section which morphologically is very distinct. All are uncommon or rare and grow in wet, nutrient-rich places and there is little doubt that many British populations have been extinguished over the years with the draining of suitable habitats.

Section 4. Spectabilia: Recent work has suggested a narrower concept than hitherto for members of this section. The achene shape and size alone clearly separate the species from those of other sections. A study of holotypes and the plasticity of British material through experimental work has suggested that there is essentially only one very variable but very common species in Britain with, at most, a couple of very restricted rarities. Plants previously called Taraxacum eximium Dahlst. and T. spectabile Dahlst. are now all included within Taraxacum faeroense.

Section 5. Naevosa: This is a largely native section with many endemic species. These are mainly confined to western and northern Britain in grassy places in the uplands. Not surprisingly then, there are some common Cumbrian species. With a few exceptions (e.g. Taraxacum subnaevosum), the plants are robust with large capitulae. Pollen is often absent. The chief morphological characteristic of this section is the presence of pigment spots on the upper leaf surface. The unwary can confuse these with disease or the midrib blotch of many species belonging to other sections.

Section 6. Celtica: As the name suggests, the species of this section are concentrated in oceanic areas and thus Cumbria is well represented by members, some of which are abundant. All the species are thought to be native and some are endemic. It is a somewhat heterogeneous section and merges into several others, in particular section Hamata. However, it seems to be a very convenient grouping which serves to reduce the genus to more manageable chunks.

Section 7. Hamata: This section forms a fairly coherent grouping morphologically. The species also share a chromosomal peculiarity. Their status in Britain is somewhat difficult to ascertain as most tend to behave in a weedy fashion. Some, if not most, are nevertheless undoubtedly native. They include some of Britain’s most abundant species and the Cumbrian picture mirrors this. Collectors (and referees!) should avoid small and immature material with even greater determination than usual, for this is the most ‘critical’ of the sections.

Section 8. Ruderalia: On the open road on a sunny mid-April day, the carpet of yellow along road-verges and on roundabouts speaks to the botanist and layman alike, that spring is truly here again. For the taraxacologist, in addition, there is challenge – even potential panic. For almost all these dandelions will belong to the section Ruderalia. Since this section contains more than half the known (and unknown!) British dandelions, and there being a considerable pool from the Continent to draw upon as introductions, it is perhaps not surprising that difficulties of identification loom large. Moreover, their generally robust size can understandably deter even the most ardent collector. Even when not so deterred, the authority to whom the student sends his collection all too often finds himself faced with poorly presented and ill-dried material. Small wonder then that this section poses most problems for the taraxacologist and flora-writer.
Yet much can be said to redress this gloomy introduction. The really common British (and Cumbrian) dandelions are relatively few and quite well understood. There is little doubt that many of these are native too, for whilst straying into ruderal habitats, they present certain clues which suggest this status.
In order then to simplify the matter, the author has decided to treat this section in a different way from the others. The first part will deal with the more significant species (as far, that is, as the author feels them to be so). These will generally be common. Most too are probably native and can be assumed to be so unless stated otherwise. The second part will deal much more briefly with a motley collection comprising species with few records, or those which are not well-understood, or even in some cases as yet unpublished. In this part it ca n be assumed that the species is probably introduced unless otherwise indicated. [NB: these two ‘parts’ refer to the treatment in the Flora,but not followed in the online treatment.]
For most dandelions (and indeed for many British plants) there are problems of ascertaining the status of each species and the whole spectrum of problems can be illustrated in this section. However, some are known to be pan-European (e.g. Taraxacum alatum); some are certainly common natives, though not confined to these islands even though we may be the main centre of distribution (e.g. T. cordatum); some appear to be widespread endemics (e.g. T. stenacrum); some, one can be fairly certain, are introductions even if widespread in Britain, for they never seem to be found away from the edge of main roads (e.g. T. undulatiflorum). In other cases, determining the status is more difficult: for example, one does not know whether one is looking at the remnants of a relict native species or a casual introduction. 2 In other instances (e.g. T. fasciatum and T. sellandii), the species can be abundant on roadsides but is occasionally found in semi-natural grassland. Further studies should help elucidate at least some of these problems.


Key to Sections (A Flora of Cumbria, 1997)

For details of the terminology used, see Dudman & Richards’s Handbook (1997). The species are arranged alphabetically within each section, the sections following the sequence in the Handbook and in Kent (1992). Besides leaf morphology and achene colour, the outer involucral bracts (here referred to just as ‘bracts’) are very important. In the newly opened inflorescence their orientation is particularly characteristic for each species. Three species are keyed out, these being the only representative of their sections in Cumbria.
Only one of the nine British sections, Section Taraxacum, is not represented in Cumbria. It contains very few British species which are known only from high Scottish mountains, but it is not totally inconceivable, though unlikely, that small relict populations may lurk in the Welsh or Lake District hills.

1. Small plants with small capitulae <3 cm; leaves usually highly dissected; inner and outer bracts often with corniculate appendages
  2. Achenes grey-brown, pyramidal cone <0.5 mm; lvs often with > 6 pairs of lateral lobes  > T. obliquum, Section 2. Obliqua
  2. Achenes usually reddish to yellowish-brown, cylindrical cone c.l mm; lvs rarely with > 6 pairs of lateral lobes    Section 1. Erythrosperma
1. Plants not as above, generally more robust and with achenes with a shorter conical cone
  3. Leaves grass-like; outer bracts broad, tightly adpressed and with a scarious border, plants of basic, wet habitats  > T. palustre, Section 3. Palustria
  3. Plants not as above
   4. Plants small but capitulae relatively large; leaves ovate to lanceolate, almost entire or with many recurved lobes, often spotted; bracts ovate and erect to adpressed; achenes (with cone) at least 5 mm; oblong; very variable plants of moist or boggy habitats  > T. faeroense, Section 4. Spectabilia
   4. Plants generally more robust and with achenes rarely more than 4 mm and then more conical
    5. Lvs usually conspicuously spotted above and hairy; bracts rarely reflexed; pollen sometimes absent; robust plants of damp, grassy habitats, often upland    Section 5. Naevosa
    5. Lvs very rarely spotted, if so, then glabrous; bracts various; pollen usually present
     6. Lvs with red or colourless petiole and midrib; upper surface of midrib lacking green and coloured streaks. If shape complex; bracts rarely erect; pollen nearly always present  Section 8. Ruderalia
     6. Lvs with coloured petiole and midrib, upper surface of midrib with interwoven streaks (use lens), lvs generally rather flat and simple in shape; bracts seldom long or reflexed; pollen sometimes absent
      7. Lf lobes usually hamate (hooked) and rather obtuse, petiole seldom either green or brilliantly purple/red; bracts arched, short, dark, often suffused purple and pruinose; pollen always present; rather weedy in habit    Section 7. Hamata
      7. Lf lobes more triangular, patent and acute; petiole often brightly coloured; pollen sometimes absent; plants of more natural, damp habitats    Section 6. Celtica

Hawkweeds ~ Hieracium

The mapping/accounts page is here.

Species-accounts from A Flora of Cumbria (1997), for species which are covered therein, appear below the map. 62 species appear in A Flora of Cumbria; 138 are currently recorded.

BSBI Referee for the genus Brian Burrow has very kindly offered comments for a number of species where the taxonomy has advanced from the accounts in A Flora of Cumbria. These are attributed in the ‘Current comments’ pane as ‘[BB]’. Comments attributed as [JR], or lacking attribution, are by Jeremy Roberts. Further comments will be added in due course.



Introduction and key, A Flora of Cumbria (1997)

‘As novices, provokingly ignorant of hawkweed problems, and without a description of decolor (it is not indexed in Linton’s work and so we missed it) we ran this plant down to H. Leyi and feel encouraged. But what a liquid genus must Hieracium be if a plant can be put back into a ‘better hole’ behind fifty intervening species (see Lond. Cat.) without the ruffling of a ligule!’
Bucknall & White, BEC Rpt (1920) 5:827

No serious attempt was made during the Survey to investigate the hawkweed flora until 1985 although numerous specimens had been collected, in a rather desultory way, during the previous ten years. Since then, much additional material has been accumulated and, together with specimens seen at BM and CGE, considerably more information is now available than ever before. Preparation of this account has revealed a number of errors in the Critical Atlas, errors arising from misplaced dots, omissions and misidentifications. A particularly acute problem has been the unrealistically large number of species previously reported from some sites. Familiarity with the plants in the wild suggests that environmental variation is of more significance than is generally allowed for; it also engenders healthy caution in relying too much on leaf-spotting. For all its undoubted shortcomings this account at least sets out the current position and indicates the nature of the remaining unsolved problems. Considerable help was received during the early years of this study from P.D. Sell and J. Bevan. and latterly from D. McCosh, who has seen the bulk of the herbarium material. Ultimate responsibility for the taxonomic conclusions must, however, rest with the author.
As with Rubus, earlier published accounts, for example Ley & Linton (1905) as well as the previous Floras, pose serious problems of interpretation. This account is therefore based entirely on Survey material and herbarium specimens. With the exception of the rarer species, records prior to the Survey ones are only given where they are from additional 10 km squares.
The account lists 62 species which are considered to occur or to have occurred in the county. Although seven fewer than are shown in the Critical Atlas, this number still leaves Cumbria with by far the largest hawkweed flora of any county south of the Scottish Highlands. Much remains to be done. There is at least one possible new species which requires further study and many unvisited crags and gullies still beckon. The upland hawkweeds have undoubtedly declined considerably this century, chiefly as a consequence of ever-increasing sheep stocking, but it is encouraging that the Survey rediscovered the elusive Hieracium itunense and, briefly, H. mirandum, failing only with H. subintegrifolium. These last two species should now be considered extinct.

These species-accounts, taken directly from A Flora of Cumbria (1997), are of historical interest. The records date mainly from the nineteen and early twentieth century, and there have been no more recent Cumbrian occurrences of the species. The BSBI Distribution Database currently holds no Cumbrian data for them.

Avena strigosa Schreber
The only records for this uncommon and decreasing cornfield weed are the 19th century ones cited by Hodgson from St Bees (9.1, R. Wood, 1879, CLE) and Workington (9.2), a specimen from Silloth docks (1.5, J. Leitch, 1884, CLE) and Baker’s from Kirkby Lonsdale (6.7s), where it was said to be frequent in cornfields.

Berberis sp.
A non-flowering garden hybrid occurs extensively in woodland below the Long Meg mines at Great Salkeld (56.36, RWMC, 1991, LANC) and by a streamside south of Cartmel Fell (40.84s, CEW, 1995, LANC).

Hodgson gives records from Gilgarran (0.2) and Workington (9.2); there is one from Silloth (1.5, J. Leitch, I890, CLE) and later ones from Thwaites, near Millom (2.8, M. Cross, 1907), Seascale (0.0, R.H. Williamson, 1927, CLE). Buttermere (1.1, G.A.K. Hervey, 1922) and Gilsland (6.6, G.A.K. Hervey, 1945, v.c.67/70). The Atlas shows post-1930 records for the Seascale (0.0) and Millom (1.8) squares and there are also field records made during the 1950s by the Barrow-in-Furness N.H.S. from the Broughton-in-Furness square (2.8).
This southern species has declined considerably in Britain during the present century.

Bromus japonicus Thunb. ex Murray
Material of this eastern and central European species in CLE and collected at Silloth (1.5) by E.J. Glaister in 1877 and by J. Leitch in 1882 has been identified by P.M. Smith (Watsonia (1986) 16:197) as this species.

The only record of this hybrid is a specimen collected by J. Leitch at Silloth docks (1.5, CLE) in 1882. Both the parent species used to occur in the area but there are no Survey records from there. It is surprising that the hybrid has not been reported from the upper Eden valley where the parents are frequent.

Carthamus lanatus L.
A Continental species collected at Silloth in 1891 (1.5, J. Leitch, CLE).

Centaurea atropurpurea Waldst. & Kit.

Ranunculus cf. hederaceus × peltatus
A curious plant with distinctive, acute-lobed leaves was collected by W.H. Pearsall in 1913 from a peaty drain close to the River Leven at Haverthwaite (5.8s, YRK). It has been tentatively identified by S.D. Webster as this hybrid. Material was distributed by Pearsall (BEC Rpt not traced). The cutting appended to the sheet indicates general agreement that Ranunculus peltatus was one of the parents and E.S. Marshall surmised that R. omiophyllus might be the other. Cook (in Stace 1975) gives no record for the R. hederaceus hybrid and only one for that involving R. omiophyllus.

Ranunculus parviflorus L.
The only record is that given by Hodgson for Silloth docks (1.5, J. Leitch, E.J. Glaister, 1878, CLE), although Druce (1932) lists it for v.c.69 and Wilson comments that it occurs in Furness. The Silloth record is the most northerly in Britain.

In development! Illustrations and current comments are being prepared and will be uploaded in batches.

[Note: the current version of maps you will see shows all records currently in the BSBI Distribution Database which are at monad and tetrad resolution. We are awaiting a fresh download from the DDb, to restore display of hectad records (mostly the older records by several decades).]

Your first visit? – check out the Guide next, and perhaps the other tabs above, before selecting the ‘MAIN page’ tab to go the maps/species-accounts page.

Guide: to ‘MAIN page’ maps/species-accounts
For clarity: hectad is a 10×10km Ordnance Survey square, tetrad is a 2×2km square, and monad is a 1×1km square. A few older records are at quadrant scale, 5×5km. (Note: the maps here using BSBI map data are to monad scale at best. If you are seeking more precise information, see ‘Resolution’ at the bottom of the page.)
Three input boxes:
On any device (but especially on mobiles!) select Box 3. The keypad raises on mobiles. Start to type. The site cleverly decides between a scientific or a vernacular name, and shows, in Box 1 (scientific) or Box 2 (vernacular), the alphabetic first name that matches your typing so far. Click the box displaying the name, or tap the up/down arrows, to show the full list of matches, and select from that. Typing further obviously shortens the list until the name you seek appears, along with its map/account.


Alternatively…
A: on big screens with keyboard, select either of the first two Boxes: 1 (scientific) or 2 (vernacular). Full lists of Cumbrian species appear.
Then either – scroll to the name you seek and select, when its species-map/account appears below, or – simply start to type the name over the list (nb: without pause! – if you pause, you lose!): now the first name matching your typing is highlighted at the bottom. Type more to reduce the list further, or it may be easier to scroll to the one you seek. In large genera, e.g. Juncus, it is quicker to type beyond the genus into the specific names.
B: On mobile devices, tap either of Boxes 1 or 2, then scroll, and select. Scrolling can be tedious on mobile, although there is a narrow and short-lasting scrollbar that you might with some practice be able to pick up and drag, when it is very quick.

No name matches? If not your spelling or typos, probably a name-change. Go to Plant Atlas 2020 and put the name you seek into the search box: the superseded name will be recognised, and its current name displayed.

When you open the drop-down list in Box 1, note especially the top two items ‘All species’ and ‘All records’. These are extremely useful! [nb: these may take some time to load for the first time (hence the “Please wait” message), but are more rapid on repeat.]
When ‘All species’ has loaded, check/uncheck the checkboxes to select any combination of hectad, tetrad, monad or quadrant to show or be hidden.
pastedGraphic.pngSelect one square of interest to bring a popup with the number of species and the year-range of the records. Scroll down, to find the species recorded!
(You can drag-select and copy-and-paste from this list across to a text-editor. Convert to an actual list using ‘Find-and-replace’ : search for “ | ”  and replace by a line-feed or return character appropriate for your system.)
In ‘All records’, select the hectad, tetrad or monad scale you want, and select a square to see the number of records and year-range in the popup. (The latter is a very useful indication of how recent, or not, is the information for that square.) Note that, for hectad or tetrad squares, the number of records displayed is for records at that scale, and does not include records at the finer monad scale (hence tetrad NY45S reports 414 records, whilst monad NY4654, one of the four monads within that tetrad, reports 700 records).

Mapping   With an individual species, use the checkboxes to select which scale of squares are shown. Select a square at any scale to find the number of records of the species and the year or year-range.pastedGraphic_1.pngAs you zoom in on the map, the resolution of the underlying map display increases. (If the ‘grid’ checkbox is selected, a one-kilometre grid appears beyond a certain zoom-level.)
The ceremonial boundary of Cumbria is indicated in black. The internal boundaries of Vice-county 69: Westmorland (to the southeast) and of Vice-county 70: Cumberland (to the northwest) are indicated in blue. Sedbergh parish, actually part of Vice-county 65: North-west Yorkshire, is in the southeasternmost portion of Cumbria.

Year-ranges   The recording survey for A Flora of Cumbria (see ‘Back-story’ below) covered the years 1974–1997. Years 1998–9 were something of a break in recording, after the intense years of the Flora survey; these years have been appended to ‘the Flora years’, hence the range 1974–1999.The ranges 2000–2019 and 2020–present are the years of the previous and current recording cycles of the BSBI. In general terms, if ‘tetrads’ only is selected the map will show (within a close approximation) the survey results from the Flora, in blue. Tetrad was the scale used for much of the recording in those years. Selecting ‘monads’ will show, in the great majority of cases, the two more recent year-ranges, in red or green, as the change from tetrad- to monad-recording was introduced through the 2000–2019 period. NB: where there are records straddling several year-ranges, the tint of the resultant square (of whatever scale) reflects only the most recent range. 

Illustrations   These are being collected at the time of writing and will be loaded in batches going forward. Where there is an illustration, the button(s) at lower left indicate how many images are available. Click/tap/swipe as appropriate to cycle through them. The small ‘four arrows’ icon at the lower right expands the image to full-screen. ‘Escape’ to return. 

Species-accounts   [To see what the species-pages should look like when completed, follow this link to Lathyrus linifolius.]
If A Flora of Cumbria includes a species-account for your selected species – as it does for the majority – this account appears below the map, after any illustrations. The last line of the Flora account, such as ‘Map 1109 1687  LWFCY’ references: i) its distribution map in the Flora; ii) the number of tetrads in which it was recorded during the Flora survey years; and iii) the vice-counties within which recorded in that survey (C = Cumberland, v.c.70; F = Furness, v.c.69b (part of VC69); L = part of West Lancashire, v.c.60; W = Westmorland, v.c. 69; Y = part of North-west Yorkshire, v.c. 65).
We anticipate in time also lodging on the website the introductory chapters and other material from the Flora.

Current comments   Texts for this pane are being prepared and will be installed at intervals. A few genera and species already have current comments: see Carex and Lathyrus.


Resolution  As mentioned above, mapping from the BSBI database is to monad (1km × 1km) scale. Remember that there is much more information, often to more precise resolutions, for rare and scarce species in The Rare Plant Register of Cumbria (Halliday & Porter, 2014), still in print. Work on updating the information is ongoing.
