4 KEY TO BRITISH RUBI. 
When growing in woods, very similar to R. pallidus W. & N., but 
readily distinguished from it by its more unequal prickles, acicles 
and stalked glands and less diffusely branched pan., and also 
usually by its rounder, less acuminate, less deeply toothed and less 
cordate-based term. lt. In open sunny places the plant becomes 
much stouter, its 1. lose their soft hairs, and its broadly pyramidal 
and nearly naked panicles are enormous. It then recalls the next 
species and rosaceus.

St. prostrate, bluntly angular, apparently quite glabrous, yellowish 
on the under side, bright red above, densely clothed with slender acicles, 
bristles and stalked glands of all sizes. Prickles also remarkably 
crowded, very. long-based, very slender, declining, faleate and deflexed. 
L. 5-nate-pedate to 8-nate, subpersistent. Lis. green, subylabrous, 
acutely doubly incise-serrate, acuminate; term. broadly roundish- 
ovate or slightly obovate, with long, gradually acuminate point and 
subcordate base. Pan. lax, with fleauose hairy rachis (armed like the 
st.) and crowded ultra-axillary rounded top; its lower ]. 5-nate. Dors. ° 
giving the pan. as a whole a less markedly pyramidal outline than 
In viridis. 
_ So far found only in Dors., though in at least three or four 
distinet localities and in considerable quantity, and showing no 
noticeable variation under changed conditions of shade and soil.

Mg} ft with many 
short shining hairs beneath, with acute crowded teeth, which are nearly 
te 1. but € more compound in the 5-nate ; 
erm. obovate-acuminate or cuspidate-acuminate, with narrowed - 
somewhat obtusangular truncate base. Pan. only slightly narrowing 
above into the conspicuously cylindrical ultra-axillary top, with many 
longish patent or even divaricate 1-3-flowered branches and sub- 
sessile term. fl.; the slightly flexuose rachis and the ped. more or 
less felted above, densely hairy, with many very slender aciculate
