 petioles spreading-hispid, sometimes very sparsely 

 so; leaf -blades 2 to 5 inches long, appressed-hispid, 

 either green or grayish, pinnate or pinnatifid, the 

 large terminal lobe elliptic to lanceolate, with 1 to 

 several pairs of smaller or of much reduced leaflets 

 or lobes below, or entire; petioles commonly long; 

 racemes dense, 1 to 2 inches long, mostly rather 

 short-peduncled, the peduncles subterminal in a close 

 panicle or compact cyme; calyx-lobes oblong; co- 

 rolla purple or pale lavender, bowl-shaped, 2 to 3
