Perennial, stems simple, several to many from a thick root- 

 stock, 3 dm. high, pubescent with white, somewhat appressed 

 hairs, and apparently puberulent beneath these, leafy: basal 

 leaves few, their petioles 1.5 dm. long, those of the stem leaves 

 successively shorter, the uppermost 1 to 2 cm. long, pubescent 

 like the stems; leaflets about 9, densely white villous, narrowly- 

 lanceolate, 3 cm. long, 4 mm. wide, acute or short acuminate: 

 peduncles short, 3 to 4 cm. long: inflorescence rather loose, idm. 

 long or less: bracts lanceolate, acuminate, 6 mm. long, 3 mm. 

 wide at base, persistent, densely white villous, as are the pedi- 

 cels and calyx: pedicels 4 mm. long: calyx with a lanceolate 

 bractlet at the base on either side which sometimes protrudes 

 above the sinus; lobes nearly equal, the upper 7 mm. long, cleft 

 into lanceolate, acute divisions, with practically no sinus, the 

 edges of the divisions almost touching; lower lobe 8 mm. long, 

 shortly 3-toothed: flowers violet-blue, 12 mm. long, 10111111. deep, 

 distance between apices of banner and wings about 4 mm.; ban- 

 ner with the sides turned back and parallel, a space of about 

 4 mm. between the edges, the face yellowish or whitish, a little 

 more than half its length concealed by the wings, the free por- 

 tion with a narrow groove, the banner nearly orbicular when 

 spread out, 12 mm. across the middle; wings rather broadly in- 

 flated, open and loosely inclosing the keel, 6111111. deep, not 

 strongly curved dorsally; keel not strongly curved, violet toward 

 the rather thick apex, the margins ciliate except at the very 

 base and apex, 4 mm. deep at the middle.
