NOTES ON ENGLISH RUBI. 133 



36. R. melanoderma. — This name may be provisionally given 

 to the bramble determined by Prof. Babington as melanoxylon (ride 

 Journ. Bot. 1887, pp. 21, 22). The true R. melanoxylon MneU. et 

 Wirtg. resembles a weak glabrous R. villicaulis (calratus) bearing 

 some glandular sets. The R. mclano dermis, however, is a small, 

 low, and very glandular bramble. It may be a variety of Wirtgen's 

 plant, but at present I do not venture to pronounce a certain 

 opinion. I have seen R. melanoderma with Mr. Rogers at Brank- 

 some and West Moors, Dorset; and at Milton, S. Hants. A dried 

 specimen gathered near Shirley, Derbyshire, by the Rev. W. R. 

 Linton approaches somewhat more the true R. melanoxylon.

37. R. fuscus W. et N. — I collected this species with Mr. 

 Rogers at Milton, and near Sway, S. Hants. A closely-allied 

 bramble seems to be more frequent in England than the true 

 R. fuscus. It has broader leaflets than this species, and the sepals 

 embrace the fruit. I have seen it in the Leigh Woods, near Bristol, 

 where it is abundant. Besides this variety, I have received from 

 different parts of England dried specimens resembling R. fuscus, 

 but more or less anomalous.

38. R. pallidus W. et N. (not of English authors). — Rare in 

 England. I possess a specimen gathered by the Rev. E. F. Linton 

 near Sprowston, Norfolk. 



Cont. distrib. Denmark, N.W. Germany, N.E. France. 



39. R. scaber W. et N. — Bickleigh Vale, near Plymouth, where 

 I collected this species with Mr. Briggs. 



Cont. distrib. Germany (very local), France. 



40. R. longithyrsiger Lees. R. pyramidal is Bab. — Seen with 

 Mr. Briggs near Plymbridge and several other places in S. Devon. 



Cont. distrib. Unknown. 



41. R. foliosus W. et N. R. Guentheri Bab. prius. R.flexuo- 

 sus P. J. Muell. 1859 (non Lejeune, 1824). R. derasas Lefv. et 

 Muell. R. saltuum Focke. — Seen between Lymington and Sway, 

 S.Hants; Daggons, Dorset ; Bickleigh Vale, Devon. Besides the 

 patent hairs on the branches of R. jiexuosus, I have failed to detect 

 any differences between Mueller's description of this species and 

 that of R. derasus. My R. saltuum agrees exactly, except in the 

 colour, with either description. R. jiexuosus and derasus are said to 

 have whitish or pale pink petals, and green styles ; in the typical 

 R. foliosus the styles are green, and the petals white ; in my 

 R. saltuum the styles red, arid the petals pink. Mueller and 

 Genevier would have thought these differences to be sufficient for 

 the establishment of specific distinction. I believe that the weak, 

 piuk-flowering R. saltuum is the product of a sandy soil or granitic 

 rocks. The white-flowering varieties are generally stronger, and 

 occur in a soil mixed with clay and a little limestone.
