or on short leafy axillary branches as well at the ends of the branches; bracts pubescent or 

 puberulent, glandular-punctate. Calyx-tube more or less densely pubescent and usually 

 conspicuously glandular in the intervals; lobes filiform from a broad base, plumose, longer than 

 the tube. Corolla pink, white, or ochroleucous, turning purple or brownish in drying. Wings 

 and keel-petals inserted far below the middle of the staminal tube, the keel-petals the larger. 

 Pod villous and glandular-dotted above.

 calyx-tube broadly campanulate, 10-ribbed, with a row of glands in most of the intervals, 

 pilose, 2.5 mm. long; lobes plumose, filiform from a triangular base, the lowest one 4 mm. 

 long, the rest 3 mm. long; corolla yellow, turning dark-purple, the petals usually with a large
