78 ON THE EUBI LIST IN 'LONDON CATALOGUE,' ED. 9. 



E. ARGENTATus P. J. Muell. No. in Set, 30. 13 v.-c. (4-6, 

 8-10, 17, 34-38, 58). Probably very widely spread, but usually 

 witb more elliptic and longer-pointed leaflets than in the Hereford- 

 shire specimens representing it in the " Set." 



Var. b. rolnistm (P. J. Muell.). 9 v.-c. (4-17, 23, 49). Pointed 

 out to me in three counties last summer by Dr. Focke. A very 

 strong handsome plant going off from li. argentatus towards R. 

 pubesccns, with crowded long prickles nearly straight on the stem, 

 but more or less falcate on the panicle-rachis, thick incised and 

 irregularly cut leaves (very white-felted beneath), and a long showy- 

 flowered panicle. Here, I think, will probably come some of the 

 plants formerly named 11. maooacantlms Blox. ; but I do not 

 feel that I can yet separate R. rohustus with certainty from its allies. 

 Genevier [Ess. Man. p. 214) describes the stem as "glabre ou 

 glabrescente," referring perhaps to its state late in the season, as 

 in my specimens, gathered early, the stem is pretty thickly clothed 

 with short crisp hairs. 



R. KUSTicANUs Merc. No. in Set, 32. 62 v.-c. (1-18, 21-24, 

 26-30, 32-46, 48-52, 54, 55, 57, 58, 62-65, 67, 69, 71, 75, 91, 100, 

 110). I. Perhaps really absent from some of the Scottish counties, 

 though hardly from any of the English. I omit varieties as too 

 uncertain and ill-defined. 



R. PUBESCENS Weihe (sp. collect.). 17 v.-c. (2, 4, 6-9, 16, 17, 

 21-24, 27, 36, 38, 49, 57). I. The name is here applied in an 

 aggregate sense only, and exclusive of the fullouinij plant. 



Var. b. subinennis Rogers, Journ. Hot. 1894, 45. 8 v.-c. (9, 

 11-13, 17, 22, 34, 36). Dr. Focke saw this growing in Berks and 

 Surrey last summer, and considered it distinct from any form 

 known to him on the Continent. It is the plant described as " /i. 

 jjubescens Weihe?" in Journ. Bot. 1892, 203, differing greatly from 

 the type in its much narrower leaflets and nearly unarmed paincle; 

 while further, when growing in shade or in dense thickets (as it 

 often does), the 5-nate leaves frequently give place to 3-nate or 

 4-nate-pedate ones. In several particu.lars it recalls R. ramostis, 

 especially in the ashy felt on panicle-rachis and the under surface 

 of the leaves, and in the weak armature ; but it differs greatly in 

 the hairy stem, the narrow cylindrical panicle, and the elliptic- 

 acuminate leaflets with long points. 



R. THYRsoiDEus Wiuim. (sp. collect.) ; Journ. Bot. 1893, 45; 

 1894, 45. 13 v.-c. (3, 10, 14, 17, 32, 35, 36, 49, 53, 55-58). [92] . 

 Perhaps doubtful in two or three other of the vice-counties named, 

 besides S. Aberdeen (92) ; but, I believe, certainly the true plant in 

 most of them. 



R. siLVATicus W. & N. 13 v.-c. (2-5, 8, 9, 17, 20, 22, 35, 36, 

 40, 49). I. Apparently thinly but widely spread. 



R. MACROPHYLLus (sp. collect.l. 62 V.-C (2-11,13-18,20-28, 

 32-42, 45, 46, 48, 49, 52, 55-59, 62, 63, 65, 68, 69, 72, 81, 84, 86, 

 88, 92, 95, 96, 98, 100, 106). I. Inclusive of the following 

 "varieties." 



a. R. iiutcrophi/llus W. & N. 52 v.-c. (All as in sp. collect., 

 except the following ten ;— 32, 33, 39, 52, 56, 63, 84, 98, 100, 106). I.
