102 NOTES ON ENGLISH RUBI. 



stalk, and the roundish (broadly obovate, elliptic, or orbicular) 

 shape of the terminal leaflet. The typical R. rhamnifolius has 

 angular glabrous stems, a compound panicle armed with frequent 

 broad-based hooked prickles, and small white flowers. The upper 

 surface of the leaves is quite glabrous ; the under side is generally 

 covered with a close white felt, which, however, disappears in deep 

 shade. In my var. stenoplos the prickles of the flowering branch 

 are slender and declining. The English R. rhamnifolius I saw with 

 Mr. Rogers in several places near Bournemouth has the same 

 armature as this var. stenoplos, and is distinguished by larger 

 flowers, and a hairy upper surface of the leaflets. Unfortunately I 

 have never seen the other continental varieties and segregate 

 species growing at then' natural stations. The French R. dumosus 

 Lefvr. seems to be near many forms of the English R. umbrosus. 

 What has been named R. wnbrosus by Fries is a form of R. Linde- 

 bergii P. J. Muell., I believe. This species has a hairy stem, and 

 an inflorescence which is either quite racemose or has only short 

 branchlets. R. Muenteri Marss. has leaves green on both sides, 

 and a narrow inflorescence ; my R. Maassii is nearly the same, but 

 it has quite glabrous stems. Many dried specimens named R. 

 umbrosus, and collected in the northern parts of England, seem to 

 be quite typical R. Lindebergii P. J. Muell., and others are not 

 distinguishable from R. Muenteri. The R. umbrosus I saw with Mr. 

 Rogers near Bournemouth has a compound panicle, and resembles 

 R. dumosus Lefvr. As far as I see, there are too many connecting 

 links between the segregate species to allow a clear distinction. 

 I have seen the English R. rhamnifolius near Bournemouth 

 (Branksome, Daggons, &c), Bristol (Leigh Woods), and Plymouth 

 (Egg Buckland) ; the R. vonbrosns at Bournemouth, S. Hants ; 

 Branksome and Daggons, Dorset. 



Cont. distrib. of the aggregate R. rhamnifolius. S. Sweden, 

 Denmark, N. Germany, N. France. 



10. R. carpinifolius W. et N. — I have not met with tins 

 species on my botanical walks in England. I have seen, however, 

 many dried English specimens as well at Kew as in several 

 collections sent by my English friends from Surrey, Warwickshire, 

 Staffordshire, Yorkshire, &c. They were named R. ajinis, rhamni- 

 folius, incurvatus, hamosus Genev., or nitidus. 



Cont. distrib. N.W. Germany, Belgium?, France. 



11. R. Lindleyanus Lees. — Seen in S. Hants (between Lyming- 

 ton and Sway, Milton), Dorset (Branksome, Canford Chine, West 

 Moors, Gore Heath, Daggons), and near Plymouth. The plant is 

 near R. vulgaris W. et N,, but I think it can be kept distinct. 



Cont, distrib, N.W. Germany (local, but hi some places 

 abundant). 



12. R. erythrintjs Genev, — R. near Ldndlezanus. Archer Briggs, 

 Fl. Plym. p. 112 (last paragraph). The plant seems to be little 

 known in England, and I hope Mr. Briggs will give a full 

 description of it. I have seen it with Mr. Briggs at many places 

 around Plymouth, and with him and Mr. Rogers near Daggons,
