most exactly R. apiculatus (Weihe), ‘ Rub. Germ.’ t. 24, in which 
the leaves are sometimes quinate, and are so represented on that 
plate ; but the leaves of our plant are not “ pubescenti-albida ” 
on the under side. 
5. infestus ; aculeis multis validis brevibus valde declinatis, pilis setis 
aciculisque brevissimis paucis, foliolo terminali oblongo-acuminato 
subtus pallide viridi tomentoso, panicule oblong ramis brevibus 
paucifloris aculeis multis longis tenuibus declinatis. 
The short declining or even hooked prickles with very thick 
bases are characteristic of this plant. Its panicle is nearly simple, 
with a few simple floral leaves below and lanceolate or trifid 
bracts in its upper part. It differs shghtly from R. infestus 
(Weihe), ‘ Rub. Germ.’ t. 30, which has roundish-cordate leaflets 
and shorter prickles on the panicle. 
e. fuscus ; aculeis paucioribus declinatis, aciculis setis pilisque multis, 
foliolo terminali elliptico subcordato cuspidato, paniculz anguste 
ramis brevibus paucifloris corymbosis aculeis brevibus tenuibus.

The panicle of this plant is usually furnished with numerous 
long unequal setz standing prominently out from its hairy co- 
vering ; but in a plant from Bearhaven, co. Cork, which seems 
referable to this variety, the setze on that part are almost alto- 
gether wanting, and the few that exist are hidden in the dense 
hairy coat.

Obs. 1. The several plants which I have now included under 
the name of R. Kehleri have all been considered as distinct 
species by high authorities. I firmly believe that they are so 
connected together by intermediate forms as to constitute but 
one species. It is often difficult to determine under which of the 
named forms some specimens should be ranged. They are all 
well marked by the numerous strong and very unequal prickles 
on the barren shoots, of which the smaller so merge in aciculi 
and. stiff aciculiform setze, those in true sete and these last in 
hairs, that it is impossible to say where one of those forms of 
armature begins and anotherends. The typical variety is known 
by its very strong and very numerous prickles combined with 
acuminate leafiets ; 8. by similar but shorter prickles and cuspi- 
date leaflets. In y. the prickles of the barren stems are more
