This is very similar in habit to the former species, but from 
the solitary specimen I have seen, it appears altogether more 
diminutive, the branches extending only three or four inches 
in length: the leaves, however, are larger in proportion; the 
blade is broadest at the base, contracted in the middle, and 
terminates in a narrow, obtuse, and mucronulate apex; at base, 
it tapers gradually into a narrow linear petiole of equal length, 
being altogether one inch long, and three and a half lines broad : 
they are thick and fleshy, and without any apparent venation : 
the flowers are five or six lines long; the corolla is broader in 
proportion, and, as well as the calyx, is covered with short rigid 
jointed pubescence: the calycine segments are broad, foliaceous, 
oblong, pointed, three of them being half as long as the corolla ; 
they are very distinctly veined, with three almost parallel nervures, 
connected together by several retrorsely branching veins: the tube 
thickens, as in the preceding species, into a hardened nut-like 
body, which, in like manner, becomes conglomerated with the 
axillary node; it is crowned with its persistent foliaceous lobes, 
which, however, do not become spinescent, as in the former 
species. The structure of the flower, the stigma, and the seed, 
exactly resemble that of S. spinescens, except that the stamens 
are in some degree shorter, the anthers scarcely rising above ee B 
middle of the tube of the corolla.* p.
