This appears to be a very fine species, resembling in its aculeate stems and peduncles 
S. aculeata, but with much larger stipules, inflorescence, and fruits than in that species.

A slender shrub growing near water; branches ascending, slightly angular when 
older, finely and rather laxly pubescent ; young growths densely silky-pubescent. Leaves 
three or four times as long as the inflorescence, about 12 cm. long; rachis thinly 
pubescent ; leaflets 12-18 pairs (usually about 17 pairs), shortly stalked, elongated-oblong, 
rounded on one side, slightly narrowed on the other, rounded and with a prominent 
subulate mucro at the apex, 1-5-2-3 cm. long, 5-6 mm. broad, glabrous but densely 
covered with minute black spots above, adpressed silky-pubescent below; stipules soon 
falling off, linear-subulate, very acute, 6-7 mm. long, with narrowly membranous edges, 
shghtly pubescent up the middle; stipels minute. Inflorescence about 3 cm. long, or up 
to 8 cm. very slender, simply racemose or rarely branched ; peduncle thinly pubescent ; 
pedicles about 5 mm. long; bracts like the stipules, but with wider membranous margins, 
soon falling. Flowers yellow, about 1 cm. long; buds ellipsoid, beaked at the apex, about 
5 mm. long, glabrous. Calyx campanulate from a broadly turbinate base, 5 mm. long, 
with five broadly triangular acute lobes slightly puberulous on the margin. Vezillum 
probably not spotted, about 8 mm. long, with two wholly adnate appendages on the claw. 
Alae about 8 mm. long. Carina limb as long as the claw. Ovary and style glabrous. 
Fruits curved, about 15 cm. long, 3 mm. broad, with thickened margins, acutely beaked,
