thick, glabrous above, minutely strigillose beneath ; stipules obsolete ; 
racemes subsessile, laxly few-flowered, scarcely exceeding the leaf; calyx 
pubescent, bluntly 5-fid ; petals pubescent ; legumes terete, straight.

branched, strigoso-canescent, the terete branches and twigs spinescent ; 
leaves solitary, trifoliolate ; leaflets obovate-oblong, strigose on both 
surfaces ; stipules obsolete; racemes subsessile, much longer than the leaf, 
on rigid rachides which become spinous ; calyx canescent, shortly 5-tooth- 
ed; petals pubescent ; legumes straight, compressed, with thickened 
sutures, narrowed at base, curve-pointed, the valves somewhat keeled 
in the centre, strigose. 
Has. Among rocks near Verleptpram, Gariep, Drege./ (Herb. Sond.)

Has. Wolvekop, Zeyher / (Herb. Hk., Sd., D.) 
A scraggy, densely-branched bush, resembling J. spinescens, but not spinous (on 
our specimens), much more pubescent and cinereous, with denser foliage and differ- 
ently shaped leaflets, &. The twigs are angular and striate, and set at short dis- 
tances with prominent tubercles or abortive ramuli, which bear several tufted leaves. 
The few flowers seen (in Hb. Hook.) are solitary, on pedicels 2 lines long. Leaflets 
2-24 lines long, 1 line wide. Legume (in Hb. Sond.) 2-2} lines long, acute. 
9. I. denudata (Thunb.! Fl. Cap. p. 597, non Jacq.) ; shrubby, rigid, 
dwaricately much-branched, unarmed or spinous, subglabrous ; leaves short- 
petioled, trifoliolate ; leaflets oblong-cuneate, obovate or linear-oblong, 
obtuse, mucronulate, coriaceous, expanded, glabrous or puberulous be- 
neath, (the terminal sometimes petioled) ; stipules obsolete or minute, 
toothlike ; racemes canescent, subsessile, equalling or somewhat exceed-
