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. *Oenanthe fluviatilis (Coleman). South of England. "The fluitant form of _AE. 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 {362} 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.)
