R. affiyiis W. & N., b. Briggsianus, n. var. L. considerably 

 smaller, and greener beneatb. Term, and intermediate Us. oral -unite, 

 or slightly acuminate, with rounded or scarcely emaryinate base ; very 

 different from those of the typical plant. Pan. less leafy above, 

 very compound. St. usually weak and low-growing as compared with 

 the strong pan. 



This is the R. a finis of the Fl. Plym.; a frequent plant in Dev. 

 and E. Cornw., where it takes the place held by the type in 

 S. Engl. It may prove our prevailing, if not our only, form in the 

 extreme west, as the Eev. E. P. Murray has found it in Somerset, 

 and Mr. Griffith (so far as I can judge from a rather imperfect 

 specimen) in N. Wales. 



In Potonie's German Flora (ed. 1, p. 253) Dr. Focke proposed 

 making R. rhamnifolias W. & N. an aggregate species, and dis-

we find "R. rhamnifolins W. & N." introduced, obviously in this 

 aggregate sense, and the explanation added that our "English 

 R. rhamnifolius" is near his var. stenophs. Dr. Focke now writes 

 to me, 1 ' My var. stenoplos, growing in the western parts of Germany 

 near the Bhine, cannot be clearly distinguished from the 11. rhamni- 

 folius of British authors." It seems best for us therefore to retain 

 the aggregate name in our lists, enclosing it perhaps in square 

 brackets to show that the typical plant is so far unknown in Britain, 

 and adding "var. stenoplos Focke" to represent our common plant. 



R. nemoralis P. J. Muell. As suggested in p. 52 of my " Essay " 

 (Additions and Corrections), this name should be dissociated from 

 the bramble (or brambles) which we used to call /,'. nmhr»sus Arrh. 

 A plant answering well to Genevier's description of Mueller's 

 ncmuralis (as Dr. Focke also thinks), is abundant in the Bourne- 

 mouth neighbourhood, and may be distinguished from its allies by 

 the following characters : — R. nemoralis P. J. Muell. (Genev., non 

 Bab.). St. rather high arching, subsulcate, glabrescent or with a 

 few short hairs. Prickles fairly strong, falcate or declining, broad- 

 based. L. 5-nate-digitate (apparently never 7-nate), fiat. Us. 

 green o« both sutes, ultimately only 8 ^8^&J P aler beneath, glabrous 



finely evenly serrate in the lower half, but often with compound

with long petiolule (sometimes nearly half as long as the It.) ; bas. 

 Its. often overlapping the interm. Pan. long and very lax, with 

 3-, 4-, 5-nate 1. below and usually several 3-lobed and simple ones 

 above, pyramidal at first, ivith the lower racemose-corymbose branches

close felt and a few loose hairs, without stalked glands; prickles 

 falcate or deflexed; bracteoles numerous, 1-3-fid. Sep. grey, 

 cuspidate or cuspidate-acuminate, usually aciculate, reflexed in fl. 

 and fr. Pet. conspicuous, narrowed below, pink. Stam. exceeding 

 styles. Hants, Dors., Somerset.
