does not agree with specimens of R. amplificatus received from 
Mr. Lees himself, which are very nearly allied to R. macro- 
phyllus. 
Obs. 3. A form of this plant occurs in Apse Castle Wood, im 
a dense shade, similar to that mentioned by Dr. Bell Salter as 
his 8. frustratus of R. Wahlbergit (Ann. Nat. Hist. xvi. 371) ; 
it is suberect with flaccid leaves and abortive flowers. This is a 
state of arrested development. He is of opinion that this state 
of the plants should be considered as a recognised variety, for 
the reason that it is a permanent form, he having noticed it un- 
changed in the same situation for many years. Its identity with 
the fully-developed form described above is proved, not merely 
by transition states, but by a plant of the erect and abortive form 
having acquired the normal condition since it has been removed 
into a garden. A similar state is found in R. discolor in more 
exposed places. I observed this latter plant im that state on 
ditch-banks near Cambridge in the autumn of 1845. 
7. R. tenuis (Bell Salt.!); caule procumbente tereti glabro, aculeis 
deflexis xequalibus validis, foliis ternatis rarius quinatis subglabris 
subtus viridibus pubescentibusque, foliolo terminali obovato-acumi- 
nato, panicula decomposita, sepalis lanceolato-acuminatis fructui 
parvo (nigro) drupeolis paucis magnis composito adpressis. 
R. tenuis, Bell Salt. in Ann. Nat. Hist. xv. 305. 
R. affinis 6, Rub. Germ. t. 3 b. 
B. ferox (Bell Salt.!); aculeis crebris uncinatis. 
Whole plant much resembling R. cesius, from which it differs 
by its stout equal and not straight prickles and total want of 
hairs and sete on the barren stems, and the stronger prickles on 
its panicle. From R. corylifolius it may be known by the strongly 
hooked prickles on its petioles, almost constantly ternate leaves, 
and longer and adpressed sepals. 
South of England. July and August. 
8. R. corylifolius (Sm.!); caule decurvo vel procumbente teretius- 
culo glabro, aculeis conicis rectis tenuibus, foliis quinatis planis 
marginem versus undulatis subcoriaceis subtus mollibus canisque, 
foliolo terminali rotundato-ovato cordatove, infimis subsessilibus 
intermediis incumbentibus, panicula subcorymbosa, sepalis ovatis a 
fructu reflexis.

R. affinis, Bab. Man. 93. 
Stems long, usually glabrous. Prickles moderate, those of 
the petioles nearly straight. Lower branches of the panicle often 
elongated and spreading. “Torus roundish-clavate.” Fruit 
sometimes rather hairy. 
Hedges and thickets, common. July and August.
