9-11, 13, 14, 16-18, 20-23, 2G, 27, 33, 34, 36, 38-40, 48, 49, 55, 

 57, 62, 65, 68, 89). I. [35, 37J . The range of variation here 

 covered is considerable. 



Var. c. silvcxtris R. P. Murray, /'"/. Somerset ; Jonni. But. 1894, 

 47. 5 v.-c. (1, 8-5, 48). A woodland form, which is probably 

 widespread. 



Var. d. PuRCHASiANus Eogers, n. var. IL Beuteri Merc. Lund. 

 Cat. ed. 8. li. ohscurus Kalt., B. E. C. Bep. 1890, 295 ; Journ. Bot. 

 1892, 389. No. in Set, 22. Dr. Focke, having seen this growing 

 in Herefordshire last August, is convinced that it must be kept 

 distinct from both B. Beuteri and /.'. obscurus, and, he thinks, 

 be placed near B. hystrix. I am pleased to be allowed to connect 

 it with the name of the Eev. W. H. Purchas, who observed it in 

 Herefordshire so long ago as 1848. 8 v.-c. (34-37, 59, 62, 91, 92). 



Var. e. infecundus Rogers. No. in Set, 70. 26 v.-c. (2-4, 6, 

 12, 16-18, 21-24, 34-42, 49, 55, 57, 59, 97). Much of the B. 

 hystrix of former times belongs here. 



Var. f. LiiKjua Bab. 2 v.-c. (2, 4). 



R. PowELLii Rogers, Journ. Bot. 1894, 47. 2 v.-c. (16, 18). 



E. ADOKNATus P. J. MucU. Joum. Bot. 1892, 338. No. in Set, 

 -71. 16 v.-c. (1, 5, 6, 9, 11, 13, 15, 17, 24, 34, 36, 38, 49, 55, 58, 63). 



E. KoEHLERi (sp. collect.). 70 v.-c. (1-9, 11-40, 42, 45, 47-52, 

 55-59, 61-67, 69, 71-74, 82, 83, 87-89, 100). 



a. B. Koehleri W. & N. 22 v.-c. (2-4, 8, 9, 11, 13, 17, 18, 

 20, 22, 23, 26, 32-34, 36, 38, 57, 59, 62, 69). I. Fairly typical, 

 I have reason to think, in the counties here enumerated ; but the 

 species is very variable. 



Var. b. pallidus Bab. (non W. & N.). No. in Set, 45. 59 v.-c. 

 (3-8, 11-14, 17-40, 42, 45, 47, 49-52, 55-58, 60-67, 69, 70, 72, 87, 

 88, 100). I. A very constant and locally abundant form, especially 

 in the north. Thought by Dr. Focke to be the same as B. hostilis 

 P. J. Muell., but, judging from specimens that he has lately thus 

 named, I suspect that he has been misled by something wrongly 

 labelled B. pallidas Bab. 



Var. c. coi/nafHs (N. E. Brown), Em/. B,)t. od. 3, Suppl. 101 ; 

 Journ. Bot. 1892, 802. No. in Set, 41. 4 v.-c. (17, 22, 27, 36). 

 Dr. Focke, now that he has seen this groAving, agrees with me in 

 thinking it (as represented by the Surrey plant. No. 41 in Set) a 

 good var. of B. Koehleri. From strong examples of that it seems to 

 me to differ chiefly by the fe\Yer strictly intermediate prickles, the 

 broader and more ultra-axillary panicle, and tbe subpatent or only 

 loosely reflexed fruiting sepals — characters which perhaps take it 

 some way towards B. BahiiKjtonii, the name at first given it by Dr. 

 Focke. I do not include the St. Budeaux and Linton Wood plants, 

 which I think different and not improbably strictly local forms. 



E. PLiNTHosTYLUs Gencv. Ess. Man, p. 108 ; Journ. Bot. 1887, 

 22 ; 1892, 340. No. in Set, 72. 4 v.-c. (2, 9, 34, 73). I now 

 follow Dr. Focke in separating this from B. Koehleri, as Prof. 

 Babington indeed did in the first instance. 



Other plants allied to B. Koehleri which have been found in 

 Britain are B. distreutus Muell. & Wirtg. (Rudyard, Staffs., W. H.
