 'acute, shortly-petioled leaves below. The main leaves 

 are lanceolate, sparsely and very slightly and irregularly

 often purplish; leaves minutely pubescent below, and 

 sometimes with very delicate, sparse, white hairs; plants 

 otherwise wholly glabrous, the blade of the leaf is usually 

 about 10" long, and the petiole as long or much shorter; 

 pedicels usually 5-8" long and filiform; pods clavate- 

 oblanceolate, about half the pedicels, inclined to be
