Stem generally decumbent, slender, round, sometimes smooth, with many branches. Leaves al- 
ternate: Petiole very short below the first pair of leaflets, bristly on the under side: Leaflets in from 
4 to 10 pairs, obovate, bristly on their margin and under side of the middle nerve, sensitive so as to 
fall when touched, like some Mimosas. Stipules often nearly hiding the stem, elongated both above 
and below the part where they are inserted with a little ear-shaped lobe on their lower half which 
runs into a very long bristly point. Flowers without smell.. Raceme short, from 2 to 6-flow- 
ered with abortive rudiments of others. Peduncle filiform, longer than the leaf immediately under 
it. Pedicel shorter than the calyx. Bractes 3; one at the base of the pedicel, similar to the stipules 
but scarcely elongated below its insertion; 2 at the top, larger, oyate-lanceolate, and resembling 
an outer calyx. Calyx ventricose, 2-labiated : lips entire, ovate-lanceolate, the lower one smaller 
and more keel-shaped, both harsh and striated. Petals yellow. Filaments equally divided into two 
sets. Anthers oblong. Pericarpium included within the calyx, divided into from 4 to 7 roundish 
muricated lobes, only connected by the zigzag style. Stigma simple. Seeds kidney-shaped.
