lately by Focke for Mr. Painter.” — C. C. Babington. “R. macrothyrsos , 
J. Lange. This plant, and that marked R. Koehleri from Menai 
Bridge, 8th September, 1888, look somewhat different, but I think 
they are variations of the same species, R. macrothyrsos , known 
only from N. W. Wales, and from a few scattered localities in 
France and N. Germany.” — Dr. W. O. Focke. 
Rubus argenteus , W. and N. R. trythrinus , Genev. Hedges near 
Woollard, N. Somerset, Sept., 1889. Name given by Dr. Focke. 
I am not aware if argenteus has been previously recognized as 
British. It occurs abundantly in two localities, five or six miles 
apart ; and is very different from all other Bristol brambles. In 
general habit it presents a close resemblance to Lindleianus , having 
the same pale tint of foliage, bright red stem, and leaflets essentially 
alike in shape and serrature. The armature also, both of barren shoot 
and inflorescence, is nearly that of Lindleianus. But the pilose 
stems, white felted leaves, and long, open leafy panicle are marked 
characters ; and there is a constant occurrence of ternate leaves on 
the lower part of the shoots. Prof. Babington in the “ British Rubi,” 
referring, I presume, to R. argenteus , W. and N., says the true 
argenteus of France and Germany is more nearly allied to discolor than 
to thyrsoideus, but seems distinct from both. In the “ Consp. Flor. 
Europ.” Weihe’s plant is placed as a variety under R. pubescens , a 
position that may fairly well suit it. — J. W. White. “I say the 
same of this as of Mr. Bailey’s plant from Wells. Can they both be 
R. gratus ? They are just like what I have so named from 
Festiniog.” — C. C. Babington. 
R. macro acanthus , Blox. Between Yeaveley and Stydd, Derby- 
shire, August, 1889. In company with the Rev. W. R. Linton, I 
found this bramble occupying an area of many acres almost to the 
exclusion of every other bramble ; and while it was obvious to us 
that it was allied to R . rusticanus , Merc., it was equally obvious 
that it was not that. The panicles were frequently of enormous 
size, two to four feet in length ; the leaflets were not convex and 
ohovate, but flat with wavy edges and ovate acuminate ; the prickles 
were remarkably long, both on the barren stem and the rachis ; the 
flowers were very pale pink, the filaments red pink, the styles greenish. 
The Rev. W. R. Linton noted on a later visit to the spot that this 
bramble fruited freely. By the assistance of the Rev. W. Moyle 
Rogers, and by comparison with specimens in his herbarium, I arrived 
at the conclusion that it was the plant named R. discolor , var. 
macroacanthus , by the Rev. A. Bloxam ; which is placed by Prof. 
Babington (‘Brit. Rubi’, p. no) under R. thyrsoideus , Wimm. ; but 
which I believe Dr. Focke, to whom a specimen has been sent for his 
opinion, separates from both these species. The name “ macroacanthus ” 
will require revision; but, as Prof. Babington has suggested (‘Brit. 
Rubi’) this may prove identical with some bramble already named on 
the Continent. — E. F. Linton. Prof. Babington writes : “ It may be 
so. I think that there is no definite R. macroacanthus of Bloxam.” 
R. rusticanus , Merc. var. macroacanthus , Rub. Germ. Rough
