Stem erect, eight to ten inches in height, somewhat appressed, 

 sUky pubescent throughout, leafy ; leaflets seven to ten, arcuate, 

 canaliculate, lance-linear acute, mucronate, narrowed at the base, 

 silk alike on both surfaces, half the length of the petiole, the upper

Flowers numerous, in a rather close alternate raceme ; bracts 

 lance-subulate, as long, or often twice the length of the pedicels, 

 caducous. 



Calyx silky villous, base spurred, and -with the upper Hp colored 

 (white), minutely bracteolate, upper lip two-toothed, short, erect;
