Iong; leaflets 11-15, 9-31 mm. long, the blades linear to linear-oblong, mucronate, prominently ribbed, copiously pubescent : stipules quite persistent, 1-3 mm. long : racemes several -flowered, borne on short peduncles : pedicels stout, becoming 2-3.5 mm. long : calyx permanently hirsute ; tube broadly campanulate ; lobes subulate above the broader bases, the lower ones nearly as long as the tube : corolla pinkish or purplish ; standard 7-11 mm. long ; blades orbicular or obovate-orbiculate ; wings 6-7 mn.

This species differs from Cracca cinerea L. by its pubescence, the shape of the blades of the leaflets, the smaller corolla and the short calyx-lobes. The type specimens were collected in pinelands between Cocoanut Grove and Cutler, November, 1904 (Small 2112).
