sterling. This gentleman has many more claims to botanical 

 distinction. 



Shrub. June — November. 



A compact bush, from 3 to 6 feet high, copiously branched, and 

 very prickly. It has much of the habit and characters of the 

 first section of the genus, and some of its smaller prickhs look 

 very like bristles ; but they are not glandular nor quite straight. 

 The curvature of all the prickles indeed is but slight, though the 

 larger ones are sufficiently hooked, as well as compressed, to 

 entitle the plant to a place in our third section, being moreover 

 allied to several neighbouring species. Leaflets 5 or 7, smaller 

 than most of this section, elliptical or roundish, acute, strongly, 

 sharply, and rather unequally, but by no means doubly, ser- 

 rated, quite destitute of glands ; the upper surface a little glau- 

 cousj rarely besprinkled with fine longish hairs ; under smooth, 

 except the ribs, which bear plenty of white hairs, unequal in 

 length and direction. Footstalks hairy and in some instances 

 prickly, not glandular. Stipulas smooth, dilated upwards, mi- 

 nutely serrated, with spreading points ; the uppermost often 

 changed for smooth, ovate, pointed, slightly serrated bracteas. 

 Tube of the calyx globular, very smooth ; segments of the limli 

 pinnate, with a few linear-lanceolate, entire leaflets, neither 

 cut nor glandular. Flowers rather small, of a light blush-co- 

 lour. Floral receptacle very flat. Styles distinct. Fruit orange- 

 coloured, roundish-ovate, sometimes almost exactly globular, 

 crowned with the upright permanent segments of the calyx, about 

 its ov.'n length.
