subulate, lax, ?”’ long; bracts lanceolate, shorter than the pedi- 
cels; peduncles axillary throughout, filiform, about 3’ long; leaves 
about 1-14’ long, the filiform petiole over half the whole; leaflets 
thick, about 4 pairs, nearly contiguous, 2-24” long, obcordate to 
oval-obcordate, with cuneate and long-petiolulate base; truncate 
to emarginate, folded; stipules not connate, triangular-acuminate, 
rather large, green above; stems very many, prostrate, much 
branched, czespitose, in small mats; nodes very many and knotty; 
internodes very short; stems perennial from a simple-crowned 
root. This has the appearance of A. lentitormis largely as to 
pods and habit, and also reminds one forcibly of A. Kentrophyta 
var. tegetarius.
