24. R. erythrinus Genev. Journ. Bot. 1890, pp. 204-206. — St. 

 high-arching, angular, nearly glabrous, dark purplish red. Prickles 

 strong, slightly declining from oblong compressed base, purplish 

 red, with yellow tip. L. 5-nate-pedate and 3-nate. Lts. sometvhat 

 convex, bright green and nearly glabrous above, softly hairy or 

 occasionally felted beneath, becoming purplish and nearly bare on 



both side3, irregularly dentate serrate, and much less wavy at the edge 

 than in R. Lindleianus ; term, long-stalked, obovate, cuspidate-acuminate, 



or occasionally nearly elliptic-acuminate, subcordate. Pan. sub- 

 pyramidal, abruptly rounded at the top (not truncate), with short few- 

 flowered subpatent ultra -axillary branches, and several long rather 

 distant ascending axillary ones ; rachis with a close coat of short hairs, 

 and sometimes felted towards the top, with rather few strong 

 declining prickles, and very rarely a stalked gland or two. Sep. 

 ovate, with short linear point. Pet. large, oval, pink. Fr. large 

 and abundant. 



Perhaps nearest to B. Lindleianus on the whole, though in some 

 respects more strongly recalling R. rhamnifolius, as, e. g., in the 

 colour of st. and 1., and in the lax and subpyramidal pan. Widely 

 distributed ; especially abundant in Dev, and Cornw. Hedges and 

 thickets. 



b. B. argenteus (W. & N.). — Lts. broader, more rounded in 

 outline, and more constantly felted beneath ; term, broadly elliptic,
