NOTES ON ENGLISH RUBI. 101 



ones are somewhat greyish and felted beneath ; the basal leaflets 

 are distinctly stalked. The sbape of the terminal leaflet is ovate 

 or cordate, gradually tapering into a long point. Near Plymouth 

 (Egg Buckland; Bickleigh, near Shaugh Bridge) Mr. Briggs 

 showed me a bramble he supposed to be my 11. opacus, and I think 

 his determination will prove to be correct, though tbe Devon plant 

 seen by me is in all parts smaller than the German species. Prof. 

 Babington at one time thought it might be 11. Jissiis, but the cha- 

 racters mentioned above will be sufficient for a clear distinction. 

 Cant, distrib. Denmark, N.W. Germany, N.E. France? 



7. R. affinis W. et N. — The figure of this bramble in tbe 

 1 Rubi Germanici ' is not good, and it may have misled many 

 students of the genus. I know the true plant from my visits to 

 Weihe's original stations, and from comparison of his own dried 

 specimens. The barren stems are tall, erect-arcuate, glabrous, and 

 remarkable for their very blunt angles and strong straight prickles. 

 The young leaves usually are white-felted beneath ; the terminal 

 leaflet is cordate-acuminate. The prickles at the base of the 

 panicle are remarkably long and slender, the flowers rather large, 

 the petals usually pale pink. The upper surface of the leaves in 

 the Dorset plant is somewhat more hairy than I am accustomed to 

 see it in German specimens. In every other respect the plants 

 from the different countries exactly agree. I saw B. affinis at 

 several spots near Bournemouth ; Alum Chine, S. Hants ; Canford 

 Chine and Gore Heath, Dorset. Dried specimens from Norfolk, 

 sent by the Rev. E. F. Linton, represent exactly the same species. 



Cunt, distrib. Sweden (very local) ; N.W. Germany (common 

 in many districts on sandy soil). The French B. Cariensis Rip. et 

 Genev. is very near. 



II. Stems glabrous or with scattered hairs, arching, often rooting at the 

 end. Usuallg no glandular seta, bat theg occur occasionally in 

 the panicle of some species. 



8. R. imbricatus Hort. — Near B. affinis, but in all parts smaller. 

 The barren stems are arcuate-prostrate and branching, very different 

 from the high arching ones in 11. affinis. The panicle is narrower 

 than in that species. I saw B. imbricatus with Mr. Briggs at 

 several places near Plymouth. 



Cunt, distrib. W. France. Prof. Clavand has sent me dried 

 specimens from the neighbourhood of Bordeaux. 



9. R. rhamnifolius W. et N. — It is very difficult to say what 

 is R. rhamnifolius, although I know the typical plant quite well. In 

 every country, and often in every province, the rhamnifolius-type 

 has a somewhat modified appearance. In England, R. rhamnifolius 

 and /.'. umbrosus generally are thought to be very different plants. 

 A good deal of the dry branches, however, we see in the herbaria 

 cannot be arranged with any degree of certainty under one or the 

 other species. The most remarkable features common to all forms 

 of the aggregate species are a very much branched stem, strong 

 prickles, a small dentition of the leaves, an unusually long foot-
