** The whole plant glabrous. Root soft and creeping. Stems ascending, 
a foot and a half long, branching at the base, flexuose, terete, striate. 
Leaves pinnate, with 2, 3, or 4 pair of leaflets, nearly opposite, with a 
terminal one at a short distance from the last pair; leaflets nearly sessile, 
oblong or obovate, obtuse or mucronate. Stipules small, membranaceous. 
Peduncles axillary, about the length of the leaves. Flowers from 6 to 10, 
in umbels, pendulous, on short pedicels, without any or with very small 
membranaceous bractew at the base of the umbel. Calyx campanulate, 
rather fleshy at the base, the rest slightly membranaceous, with 5 rather 
unequal teeth, the two upper ones being less deeply cleft, and rather longer; 
the two lateral teeth, and the inferior one, equal and linear. Petals on long 
claws, that of the vexillum distant from the others. Vexillum yellow, ovate, 
spreading, and thrown back on the calyx. Ale white, spreading, oblong, 
undulate on the margins. Carina yellow, rostrate, nearly as long as the ale. 
Stamina diadelphous, the solitary one generally without any anther. Style 
incurved, filiform. Stigma capitate. Legume straight, or slightly incurved, 
about two inches loug."— Bentham. 
A pretty perennial plant, found by Mr. Douglas in overflowed meadows

the same gratitude as those of England did to Sir Joseph Banks.
