102 NOTES ON ENGLISH KUBI.
stalk, and the roundish (bi'oadly obovate, elliptic, or orbicular)
shape of the terminal leaflet. The typical li. rhtoimi/ulim 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. Li my var. stcnoplas the prickles of the flowering branch
are slender and decliniug. The English R. rluvmdfoUuB I saw with
Mr. Rogers in several places near Bournemouth has the same
armature as this var. stenopluH, and is distinguished by larger
flowers, and a hairy upper suiiace of the leaflets. Unfortunately I
have never seen the other continental varieties and segregate
species growing at their natural stations. The French 11. dumosua
Lefvr. seems to be near many forms of the English R. umbrosus.
What has been named R. lunbrosiia by Fries is a form of R. Lindelu'i-ffii
P. J. MuelL, I believe. This species has a hairy stem, and
an inflorescence whicli is either quite racemose or has only short
branchlets. R. Muenterl Marss. has leaves green on both sides,
and a narrow inflorescence ; my R. Mdassii is neai'ly the same, but
it has quite glabrous stems. Many dried specimens named R.
mnbrosus, and collected in the northern parts of England, seem to
be quite typical R. Lindebeigil P. J. Muell., and others are not
distinguishable from it. Mucnteri. The R. ninbrusus I saw with Mr.
Rogers near Bournemouth has a compound panicle, and resembles
R. dinriosus Lefvr. As far as I see, there are too many connecting
linlcs between the segregate species to allow a clear distinction.
I have seen the English 7/. rluitiinifolins near Bournemouth
(Branksome, Daggons, &c,), Bristol (Leigh Woods), and Plymouth
(Egg Buckland) ; the R. wnbrosns at Bournemouth, S. Hants
13ranksome and Daggons, Dorset.

10. R. cARPiNiFOLius "W. ct N. — I liave not met with this
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 Avere named R. affinia, rliaumi-

11. R. LiNDLEYANus Lecs.—Seen in S. Hants (between Lymington
and Sway, Milton), Dorset (Branksome, Canford Chine, West
Moors, Gore Heath, Daggons), and near Plymouth. The plant is
near R. vuhfans W. et N,, but I think it can be kept distinct.
Cant. dUtrlb. N.W. Germany (local, but in some places
abundant).
12. R. ERYTHRiNUS Gcuev. R. near Lindleiamts 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,
