mainly. 



Stems several from a woody caudex, depressed and spreading, 

 2—4 dm. long, rather thick, sparingly and finely strigose, leafy; 

 stipules ovate, acuminate, 5-10 mm. long, distinct; leaves 10-15 

 cm. long, somewhat strigose, bright green; leaflets 8-12 pairs, 1-1.5 

 cm. long, elliptic or sometimes broadly oblong, obtuse, truncate or 

 somewhat emarginate ; spike short, on a peduncle 3-10 cm. long ; 

 bracts about 5 mm. long, lanceolate, acuminate; pedicels 1-2 mm. 

 long ; calyx about i cm. long, somewhat gibbous on the upper side, 

 more or less strigose with dark han^s, especially on the teeth; corolla 

 ochroleucous, except the tip of the keel, which is purplish ; banner 

 about 2.5 cm. long, narrow and deeply notched at the apex, a fourth 

 longer than the wings ; pod perfectly tw^o-celled, flesh}', indehiscent, 

 broadl}^ ellipsoid, usually over 2 cm. long and 1.5-2 cm. in diameter, 

 slightly pointed. 



A near relative of A. crassicarpus and A. Mexicaniis. The gen- 

 eral habit, the pubescence, and the form of the fruit are those of 

 the former, while the ochroleucous flowers, the width of the leaves, 

 and the size of the pod suggest the latter. It grows on the plains and 

 in open places in the mountain regions, at an altitude of 1 200-1800 

 feet.
