Stem arcuate-prostrate, terete or slightly angular towards 

 the end, thick, very nearly or quite glabrous but with a very 

 few scattered subsessile glands, setae and aciculi, glaucous, and 

 with scattered stellate down when young, usually greenish 

 red. Prickles moderately abundant, rather unequal, slender, 

 conical, slightly declining or patent with a longitudinally 

 dilated but oval and usually small base. Leaves quinate. 

 Leaflets nearly flat, wavy at the edge, doubly serrate, broad, 

 dark green, slightly rugose, and Avith a few adpressed hairs 

 above, paler, hairy, and felted (but sometimes only very 

 finely) beneath; basal sessile, broadly oval, acute, overlap- 

 ping the very broadly oval cuspidate intermediate leaflets ; 

 terminal roundly cordate with a small cusp, often having a 

 large lobe on each side, and thus showing a tendency to 

 divide into three ; petioles (which are flat above) and mid- 

 ribs with short declining or deflexed prickles beneath ; 

 stipules broadly linear-lanceolate. 



Flowering shoot from fuscous scales clothed with ashy 

 silky hairs, roundish, slightly hairy. Prickles subpatent, 

 large, from a long compressed base. Leaves mostly ternate, 

 rarely quinate; uppermost usually simple, cordate-ovate or 

 three-lobed. Leaflets whitish, hairy, and felted beneath; 

 lateral ovate, unequal-sided ; terminal obovate, broad, nar- 

 rowed below. Panicle leafy below ; branches corymbose.
