Island Life; Or, The Phenomena and Causes of Insular Faunas and Floras

3. Arabis ciliata (R. Br.). In Nyman's Conspectus Floræ Europææ this species is given as found in England and Ireland only. "A very much disputed form of a plant of very wide distribution in Europe and North America." (J. D. H.)

4. Brassica monensis (Huds.). "This and the continental B. cheiranthus (also found in Cornwall) are barely distinguishable from one another." (J. D. H.)

5. Diplotaxis muralis (D. C.) var. Babingtonii (Syme). South of England. "A biennial or perennial form; considered to be a denizen by Watson." (J. D. H.)

6. *Helianthemum guttatum (Mill), var. Breweri (Planch). Anglesea. "Very doubtful local plant. H. guttatum (true) has lately been found in the same locality." (J. D. H.)

7. *Polygala vulgaris (L.), var. grandiflora (Bab). Sligo, Ireland. "A very distinct variety." (J. D. H.)

8. Viola lutea (Huds.), var. amœna (Symons). "V. lutea itself is considered to be a form of V. tricolor, and V. amœna the better coloured of the two forms of V. lutea." (J. D. H.)

9. *Cerastium arcticum (Lange), var. Edmonstonii (Beeby). Shetland Is. "But C. arcticum is referable to the very variable C. alpinum." (J. D. H.) "Near to the European C. latifolium." (Ar. Bennett.)

10. *Geranium sanguineum (L.), var. Lancastriense (With.). Lancashire. "A prostrate local form growing out of its native soil in sand by the sea." (J. D. H.) Mr. Bennett writes: "I have grown G. sanguineum and its prostrate variety in sand, and neither became Lancastriense."

11. Genista tinctoria (L.), var. humifusa (Dickson). Cornwall. "A decumbent hairy form confined to the Lizard." (J. D. H.)

12. Cytisus scoparius (Link.), var. prostratus (Bailey). Cornwall. "A prostrate form." (J. D. H.)

13. Anthyllis vulneraria (L.), var. ovata (Bab.). Shetland Is. "A slight variety." (J. D. H.)

14. *Trifolium repens (L.), var. Townsendii (Bab.). Scilly Isles. "A well-marked form by its rose-purple flowers. Confined to the Scilly Isles." (J. D. H.)

15. *Rosa involuta (Sm.), var. Wilsoni. (Borrer.) Wales. "There are a multitude of forms or varieties of R. involuta, and R. wilsoni is one of the best-marked, found on the Menai Straits and Derry." (J. D. H.)

16. Rosa involuta var. gracilis (Woods). "This is considered by many as one of the commonest forms of R. involuta." (J. D. H.)

17. Rosa involuta var. Nicholsoni (Crepin). "Another slight variety of R. involuta." (J. D. H.)

18. Rosa involuta var. Woodsiana (Groves). "A Wimbledon Common variety of R. villosa." (J. D. H.)

19. Rosa involuta var. Grovesii (Baker). "Mr. Baker thinks this of no account." (J. D. H.)

20. Rubus echinatus (Lind.). "A variety of the widely spread R. Radula, itself a form of R. fruticosus." (J. D. H.)

21. *Rubus longithyrsiger (Lees). "Mr. Baker informs me that this is a very distinct plant never yet found on the continent." (J. D. H.)

22. Pyrus aria (Sm.) var. rupicola (Syme). "A very local form, confined to Gt. Britain, and owing its characters to its starved position." (Baker.)

23. Callitriche obtusangula (Le Gall), var. Lachii (Warren). Cheshire. "This is intermediate between two sub-species of C. verna." (J. D. H.)

24. *Œnanthe fluviatilis (Coleman). South of England. "The fluitant form of Æ. Phellandrium." (J. D. H.)

25. Anthemis arvensis (L.), var. anglica (Spreng). N. Coast of England. "A maritime form with more fleshy leaves formerly found near Durham. It has other very trifling characters." (J. D. H.)

26. Arctium intermedium (Bab.). "There are two sub-species of A. lappa, majus and minus, each with varieties, and this is one of the intermediates." (J. D. H.)

27. Hieracium holosericium (Backh.). Scotch Alps.

28. H. gracilentum (Backh.).                     ,,

29. H. lingulatum (Backh.).                       ,,       A var. of this in Scandinavia.

30. H. senescens (Backh.).                       ,,

31. H. chrysanthenum (Backh.).               ,,

32. H. iricum (Fr.). Teesdale and Scotland.

33. H. gibsoni (Backh.). Yorkshire and Westmoreland.

34. Hieracium nitidum (Backh.). Lower glens of the Scotch Alps. Mr. Bennett writes:—"The following Hieracia have been named by Mr. F. J. Hanbury as endemic forms. One can only safely say they are certainly not known in Scandinavia, as they have all been submitted to Dr. Lindeberg. But usually Scotch species are not represented in Central Europe to any great extent, though several do occur. Still these new forms ought to be critically compared with all Dr. Peters' new species."

35. H. Langewellense (Hanb.). Caithness.

36. H. pollinarium (Hanb.). Sutherland.

37. H. scoticum (Hanb.). Sutherland and Caithness.

38. H. Backhousei (Hanb.). Aberdeen, Banff, Inverness.

39. H. caledonicum (Hanb.). Caithness and Sutherland.

40. H. Farrense (Hanb.). Sutherland and Shetland Is.

41. H. proximum (Hanb.). Caithness. With regard to all these Hieracia Sir Joseph Hooker and Mr. Baker say:—"No case can be made of these. They are local forms with the shadowest of shady characters." Mr. Bennett writes: "H. iricum and H. Gibsoni are the best marked forms."

42. *Campanula rotundifolia (L.), var. speciosa (A. G. More). W. Ireland. "Very well distinguished by its large flowers and small calyx lobes, approaching the Swiss C. Scheuzeri." (J. D. H.)

43. Statice reticulata (Sm.). "Baker agrees with me that this is also a Mediterranean species." (J. D. H.)

44. Erythræa capitata (Willd.), var. sphærocephala (Towns.). Isle of Wight. "A form of E. centaurium utterly anomalous in its genus in the insertion of the stamens. A monster rather than a species." (J. D. H.)

45. *Erythræa latifolia (Sm.). On the sandy dunes near Liverpool. "A local form." (J. D. H.)

46. Myosotis collina (Hoffim.), var. Mittenii (Baker). Sussex.

47. Veronica officinalis (L.), var. hirsuta (Hopk.). Ayr, Scotland.

48. Veronica arvensis (L.), var. eximia (Towns.). Hampshire.

50. Mentha pratensis (Sole). Only once found.

51. Chenopodium rubrum (L.), var. pseudobotryoides (H. C. Watson).
