284 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
from Focke’s typical R. opacns, as represented by specimens col- 
lected by him near Bremen and now in my herbarium. It is also, 
I am convinced, the same form as the Somersetshire s[)ecimens 
issued as No. 78 in the “Set of British Rubi ” (1H92 — 1895}, 
and as a Dorset plant which grows in some quantity at West Moors, 
near Wimborne. With reference to the latter, submitted by me 
to Dr.« Focke in 1893, he wrote, “Quite my plant.” I may add 
however that, in its autumnal condition, especially as seen in the 
specimens now distributed to the members, it is considerably unlike 
a smaller and more ]nil:)escent#plant, which Focke distinguishes 
as his '•'•forma minor.'" The latter is represented in the “Set” 
by No. 106, consisting of specimens collected by me in S. Devon, 
where I had constant ofiportunities of becoming familiar with the 
living bushes. This small form, as stated in my Handbook, p. 23, 
is also found near Bremen “ on very j)oor and dry soil,” and is 
readily distinguished ’from the type by its greyer, more hairy, 
and more finely-toothed leaves and short-pointed leaflets : — charac- 
ters which make any confusion of it with R. sulcalus practically 
impossible. — W, M. R. 
R. afinis, Weihe and Nees. Small form. Petcrston, Glamorgan, 
28th August 1905. Some of the [lanicles, gathered at this late date, 
show great development of the lower branches. Mr. Rogers has 
seen the bushes at this locality. — H, T. Riuuelsdell. Yes. —

R. holerythros, Focke. Colgate, St. Leonard’s Forest, W. 
Sussex, 30th July 1906. — Jas. ^V. White. Yes. — W. M. R. 
R. . Woods near Apley, N. Lincoln, i6th August 1907. 
This bramble, which has been the subject of a good deal of cor- 
respondence between myself and Rev. W. M. Rogers, has at length 
been definitely assigned by him to R. mercicns, Bag., and I concur 
in the identification. New County record. — Augustin Ley. R. 
mercicus, Bagnall. Off type, towards subsp. bracteatus, Bagnall, 
especially in outline of panicle. — W. Moyle Rogers. 
R. merdais,^ Bagnall. Gathered in Market Rasen Wood, 
Lincolnshire (in company with Mr. A. Ley). I have since shown 
scanty material to Mr. W. M. Rogers, who says it “certainly 
resembles closely R. merdcus." — L. Gumming. 
R. thyrsoidens, Wimm. Wrawby Moor, N. Lincoln, 23rd 
August 1907. This is a form recalling, so far as the narrowness 
of the foliage goes, the continental R. candicans, W. ; the panicle, 
however, takes it quite away from that plant. New Vice-County 
record.— Augustin Ley. Yes. — W. M. R,
