KEY TO BRITISH RUBI. 801 



62. R. echinatus Lindl. B. rudis Bab. priue. — St. strong, 

 angular and sulcate, hairy (often densely), with crowded subequal 

 stalked glands and acicles covering the faces. Prickles long, sub- 

 equal, nearly patent, from rather narrow bases. L. 5-nate. Lts. 

 deeply incise -serrate or even lobed, remarkably acuminate and attenuate 

 below, dark and hairy above, softly hairy and greenish white-felted 

 beneath; term, obovate or narrowly elliptic. Pan. long, narrow, 

 leafy ; rachis aciculate, glandular, hairy, with rather long declining 

 or deflexed prickles; branches mostly short, ascending, axillary. 



Sep. ' with very long and strongly refiexed points. Pet. long, rather 



narrow, white or pinkish. Stam. white, exceeding the greenish styles. 

 Fr. large. Bloxam's "var. microphyllus" seems merely a small 

 state. Heaths, hedges, and waste places. 



Among our most widely distributed and constant species, 



occurring even on chalk. 



53. R. rums W. &N.— St. arcuate -prostrate, angular, generally 

 quite glabrous, rough with very short tubercles, some short acicles, 

 and crowded subsessile and shortly stalked glands. Prickles rather 

 short, but strong, and usually numerous, declining. L. large, 

 3-nate and 5-nate-pedate. Lts. unequally and very coarsely serrate, 



dark green and glabrous or subglabrous above, hairy on the nerves 

 beneath and white-felted when young, afterwards pale green, or 

 more rarely (in sunshine) grey-felted ; term, broadly ovate, elliptic 

 or rhomboid, with rounded or cuneate base, and long acuminate 

 point ; the lateral in the 3-nate 1. usually deeply cleft below. Pan 



broad, with crowded and often interlacing branches, and remarkably 

 slender ped. ; rachis and pel close-felted, and densely clothed with very 

 shortly stalked and subsessile glands, a few longer glandular bristles, 

 and a good many acicles ; 1. 8-nate, often very large ; lower 

 branches distant, erect-patent. Sep. ovate or triangular-acuminate, 

 with long points, patent or loosely refiexed. Pet. small, oblong, pink. 

 Stam. somewhat exceeding the greenish styles. Woods and bushy 

 places (Derb., Oxon, Kent, Surr., Glost.). 

 A very strongly-marked distinct species.

PR/ERUPTORTJM 



glandular 



stalked glands, and a few short hairs. Prickles many, slender, very 

 unequal, more or less declining, much compressed, narrow -based ; the 

 largest very long. L. large, 5-nate-pedate and 8-nate. Lts. coarsely, 



irregularly, and somewhat doubly crenate-serrate, rather thin and bnttle, 

 green and hairy above, paler and softly hairy on the veins beneath ; 

 term, broadly obovate-acuminate, cordate or subcordate. Pan. long, 

 narrowed above ; the axillary branches distant, erect or ascending; 

 rachis clothed like st., but far more hairy, and with very unequal 

 prickles. Sep. ovate-attenuate, loosely refiexed. Pet. narrowed 

 below white or pinkish. Stam. white, exceeding styles. Hedges 

 and woods (Norf., Herts, Middl., Kent, Dors., Dev.); apparently 



Vei A handsome plant, remarkable for its very unequal prickles on 

 st.-angles and on pan., and its thin brittle leaves.
