KKY TO BRITISH RUBI. Ill 



large in all its parts. Near 11. ajinti only in its refldXdd sep. and 

 black fruit; its nearest ally being B, subereetm, from which it is 

 readilv distinguished by the characters given above. Woods (Dew, 

 Dors.~ lleref., Perth). 



9. R. afi ims W. & N. — St. tall and remarkably suberect at 

 first, though often rooting in the autumn, bluntly angular, glabrous. 

 Prickles many, usually very long and narrow, straight or slightly 

 declining (on pan. as well as on st.). L. rather narrow, occasion- 

 ally 7-nate. Lts. wavy at edge, often imbricate and (especially 

 when young) white-felted beneath ; term, cordate-ovate, tapering 

 almost from its base to the very acuminate point; bas. shortly 

 stalked. Pan. compound, often leafy, and with somewhat cymose 

 branches. A very marked and apparently widely d tributed plant, 

 especially in the South. The usual Dev. and E. Cornw. form 

 (which I have not seen elsewhere) is lower growing, and has 

 smaller broader 1., with Its. more nearly equal to each other in size, 

 and the term, one oval or elliptic. Bloxam's "a/finis" seems quite 

 indistinguishable from II. villicaulU Koehl. I do not understand 

 vars. b. and c. of Loud. Cat., ed. 8. Heaths and moors. 



10. R. Cariensis Rip. & Genev, — Very near to II. a/finis, of 

 which it may prove only a var. ; but it has much larger and broader 

 1., more constantly white- or grey-felted beneath (especially in pan.), 

 with large compound lobate-serrate teeth remarkably directed 

 forwards, elliptic or broadly obovate term. It., large leafy compound 

 pan., and grey-felted sep. Abundant at Lynton and in two or 

 three places near Holsworthy, Dev. Mr. J. W. White has sent me 

 specimens of what I think may be the same from Somerset. 

 Heaths, peaty places, and road-sides. 



jR. nitidus, R, a finis, and II Carienw, rightly placed, as I 

 believe, among Suberecti, certainly make some approach towards 

 the next group, Rhamnifolii. 



Group 2. Rhamnifolii. — St. high-arching, often rooting at the 

 end ; glabrous, or with some scattered hairs (and then often 

 becoming bald). Usually no stalked glands. Prickles usually 

 confined^to angles, and equal. L. 5-nate, or very rarely 7-nate* 

 Sep. often white-margined as in Group 1, but always less con- 

 spicuously so, because greyer and felted. In our plants the sep. 

 are reflexed in fruit (except in carpinitolius and gratus), and the 

 stam. are longer than the styles (except in one form of villieaalis). 

 They may be subdivided as follows : 



I. Term. It. suborbicular, about twice as long as its petiolule, 

 usually whitish-felted beneath. 



N.B.— Felt, it must be remembered, is not to be expected on 



the 1. of plants growing in shade. 



(12) Dumnoniensis. (13) rhnniiif alius. (14a) / dumosus. (14b) 

 pulcherrimus. (25) argentatm (as it occurs plentifully in Hereford- 

 shire; but usually the term. It. is ovate or elliptic). 



11. Term. It. ovate, elliptic, obovate or rhomboid, about thrice 

 as long as its petiolule.
