Lab. Man. Brit. Bot. ed. v. p. 105, 
Barren stem arching-angular, sparingly hairy; prickles unequal, 
rather slender, declining, from a rather short compressed base ; 
aciculi and gland-tipped sete rather numerous, short, unequal. 
Leaves of the barren stem quinate; leaflets rather thin, green 
above, sparingly pilose greenish-white-felted beneath, with a few 
longer hairs on the veins, finely and doubly dentate; terminal 
leaflet oval, obovate-oval, or oblong-obovate, rounded or sub-cor- 
date at the base, abruptly acuminate or cuspidate. Flowers in a 
long narrow leafy panicle with short spreading corymbose branches; 
rachis and pedicels felted, stiffly-hairy, with numerous short unequal 
eland-tipped setae, aciculi, and spreading or declining subulate 
prickles from long bases. Sepals ovate cuspidate, loosely reflexed 
from the fruit. 
a, R. Radula. Weihe. 
Prickles on the barren stem unequal, terminal leaflet oval or 
obovate, doubly dentate-serrate, acuminate. 
B, Leightonii. Lees. 
Prickles on the barren stem nearly equal. Terminal leaflet 
oval or obovate, cuspidate, sharply and doubly dentate-serrate. 
y, denticulatus. R. apiculatus. Weihe? 
Prickles on the barren stem unequal, with a few aciculi and 
eland-tipped setze, and occasionally a few scattered hairs. Terminal 
leaflet broadly oval-oblong, cordate, abruptly cuspidate, finely and 
irregularly denticulate ; rachis and pedicels densely felted, sparingly 
bristly-hairy, with numerous gland-tipped sete and aciculi passing 
gradually into prickles. 
In hedges and woods. aand 6 common. y rare; near Sheffield, 
whence I am favoured with specimens by the Rev. W. W. New- 
bould, and where it has also been found by Mr. Bloxam. 
England, Scotland, Ireland. Shrub. Summer. 
A large coarse plant varying in the colour of the felt on the 
underside of the leaves from white to green, according to the 
degree of exposure to the sun. The plant placed as y, denticulatus, 
Mr. Bloxam considers the R. apiculatus of continental botanists.
