234 KfcY TO BRITISH BUBI. 



41. R. leucostachys Schleich. (in 8m. Engl. Fl. 1824). R. 

 vestitus Weihe. — St. arcuate-prostrate, bluntly angular, villous -ha try 

 and felted, sometimes with a few acicles and stalked glands. 

 Prickles long, nearly straight from dilated compressed base. L. 

 5-nate-pedate and digitate. Lts. mostly broad, wavy at the edge, 

 usually dark green, shining and somewhat hairy above, softly 

 yellowish or grey-felted beneath ; term, subrotund-cuspidate, or rarely 

 broadly elliptic or ovate, subcordate. Pan. long, narrow, cylindrical, 

 with rounded top; the rachis densely clothed with felt and villous hairs, 

 usually with some stalked glands and acicles, not unfrequently with 

 a good many; the prickles straight or declining, long and rather 

 slender, often crowded and with some strong ones intermixed ; the 

 lower branches distant, few-flowered, corymbose, ascending. Sep. 

 clothed like the rachis, ovate-acuminate, or somewhat cuspidate- 

 acuminate. Pet. roundish, bright pink, or white. Stain, white or 

 pink, only slightly exceeding the greenish styles. 



Very variable, and yet usually well marked by the very hairy 

 st. and rachis, the long straightish prickles, the long narrow pan., 

 and the roundish felted Its. It seems to hybridise as freely as II. 

 rusticanus, and (like that) is one of the few brambles which do not 

 object to the presence of lime in the soil. Hedges, wood-borders, &c. 



b. Ii. conspicuus P. J. Muell. E. vestitus Bab. prius. — Less hairy 

 in all its parts, especially in st. Lts. nearly glabrous above, with 

 close white or grey felt beneath, but wanting the softness so characteristic 

 of the type. Pan. -prickles mostly very long and strong. FL bright 

 pink. Dr. Focke seems disposed to regard this as a hybrid between 



bif 



If this is really its origin, we are 



probably mistaken in including it in our list, as li. bifrons has not 

 yet, I believe, been recognised as a British plant. 



c. angustifolins. I suggest this name to distinguish a strongly- 

 marked var. which is rather frequent in several of the S. and S.W. 

 counties of Engl., and especially attracted Dr. Focke's attention in 

 1889. L. almost wholly 5-nate-pedate. Lts. remarkably narrow, 



nearly simply serrate, with rather close yellowish felt beneath, and 

 jyrominent nerves; term, fully twice as long as broad, narrowly oblong or 

 obovate-acuminate, with long point and long petiolnle ; interm. and 

 even bas. very similar. Strongly armed with unequal prickles. 

 Otherwise like type. 



42. R. gymnostachys Genev. /?. macrothyrsos J. Lange. — St. 

 long, arcuate-prostrate, bluntly angular, striate, villous-hairy, but 

 more tbinly than in II. leucostachys, and hardly felted, mostly without 

 stalked glands. Prickles unequal, declining, or slightly falcate from 

 long dilated and compressed Jbase. L. 5-nate-pedate or digitate. 

 Lts. glabrescent above, softly grey-felted beneath, somewhat coarsely 

 serrate ; term, broadly elliptic or obtusangular-elliptic, cuspidate, 

 with subcordate or entire base. Pan. very elongate, lax, narrowly 

 pyramidal; the topmost branches 1-3-flowered* with long trifiJ 

 bracts ; the interm. distant, of nearly equal length, mostly 

 3-fiowered, also furnished with trifid bracts, and not unfrequently 

 with 1 or 2 simple ovate-acuminate floral leaves below ; the lowest 

 axillary branches 3-5-fiowered, or rarely corymbose -racemose and
