equal (mostly weengy prickles and some (often many) acicles and 
stalked glands. 1. chiefly 5-nate-pedate. Lts. thick, acutely and 
often doubly serrate, green on both sides, paler and softly pubescent

sessile. Pa m d; rachis felted and hairy, usually very 
stronaly armed with unequal prickles, acicles and stalked glands. Sep. 
ey-felted, usually erect in fr., but sometimes only patent or loosely 
reflexed. Pet. large, roundish, hardly clawed, ablally overlapping.

Separated from species of the Koraterrani and Bretarprant by 
the oe it bas. lts., large roundish pet. and large drupelets, and 
generally by a somewhat cesian aspect. Distinguished from other 
Casu pretty readily by the far more glandular and aciculate st. and 
pan.-rachis, and further to some extent by the more regular a 
more compound pan. ; but, it must be owned, the difficulty of ies: 
mination is sometimes serious enough, and is liable to be not a 
hybrid ise. 
The following appear to be the best marked of the English 
forms or vars. of this s species :— 
. ferow Weihe. R. horridus Schultz.—St. subglabrous, gre 
a good many acicles ‘and stalked glands (mostly short). ick 
very crowded on ma coma st., straight, much compressed, short-based, cen 
long slender points. L. almos t wholly 5-nate, broad. Term. It. 
roundish cbovate since eng stalhel, with truncate- -emarginate or 
entire base. Pan. usually short, and chiefly contracted into a rather 
broad rounded top, armed like the st. Sep. ovate, suddenly contracted 
into a long point, clasping in fr., grey-felted with white margin, 
Pet. usually pink. St. and pan. remarkably variable in stoutness

ibuted. 
R. diversion (Lindl.)—Very like R. ferox, but with prickles 
less crowded, more unequal and longer based, the term. It. less roundish 
and more shortly coalbel, and so all the lts. more frequently 
imbricate; while the pan. is usually ‘‘ long, leafy nearly to the top, 
with very short — os flowered, subracemose branches, often 
springing from every @ the shoot.” The sep. also are ulti- 
mately reflexed 1 (though naenity erect for a time) jk the pet. white. 
Widely distributed, and locally abundant. &. intensus Blox. seems 
to be a small strongly armed state o 
. pilosus W. & N.—-All the stems hairy and strongly armed. 
Prickles subpatent, from compressed bases, long, rather slender, 
assing gradually into crowded acicles and stalked glands. Pan. 
leafy nearly to the top; axillary branches longer and more distant 
than in diversifolius, corymbose, many- flowered. Sep. loosely
