 and branched crown; stems several, stout, ascending to erect, 2-6 

 dm tall; leaves 10-25 cm long; stipules lanceolate, 1-4 mm long, 

 not connate; leaflets 15-21, lance-oblong to elliptic-oblong, 

 1.5-3.5 cm long, as much as 13 mm broad, glabrous on the upper 

 surface at least; peduncles mostly 10-15 cm long; racemes closely 

 15-30 flowered but elongating and open in fruit; pedicels 2-5 mm 

 long; flowers spreading to slightly reflexed, white to ochroleucus, 

 about 2 cm long; calyx usually blackish hairy, 3-10 mm long, the 

 narrowly lanceolate lower teeth about 2 mm long; banner erect;

C. Local field characters—The legumes are large with a pointed 

 attenuated apex and held erect and distant from the axis of the 

 raceme. 



Flowering racemes are fairly conspiculous with large slightly 

 declined ocholenues flowers in a tight cluster which expands with 

 age.

 international trade or commerce—No interstate or international
