have seven teeth of equal length. Corolla of five petals. Standard with a firm horizontal claw, its limb erect, round, slightly notched, the two sides generally folded together, deep yellow, with a red semicircular line near the base. Wings nearly linear, obtuse, concave, with a large tooth at the base, deep yellow, horizontal, much shorter than the standard. Keel of two pale yellow, obovate, concave petals, as long as the wings, strongly connected by their lower edge, and with a tooth near their base on the upper. Stamina all nearly equal, somewhat shorter than the keel, a little declining; filaments inserted into the receptacle, cylindrical, tapering to a point; antheræ small, roundish. Germen small, green, oval, smooth, tipped with a tuft of white hair, and containing the rudiments of two or three seeds; style longer than the stamina, subulate, recurved, smooth; stigma acute.

The plant appears to abound with mucilage, especially the leaves.
