glabrous when old, becoming easily detached; leaflets glab- 

 rous, entire, drying unequally brown on its two sides, elliptic, 

 the terminal ones longer, the lateral pairs form above the 

 middle of the stalks, varying from 6 to 10 cm. long and 

 3 to 5 cm. wide, terminated into a short blunt or more sharply 

 pointed apex, base broadly rounded; petiolule less than I cm- 

 long, somewhat thickened, at first puberulent, ultimately glab- 

 rate; midrib prominent beneath, impressed above; lateral nerves 

 obscure, 5 to 7 on each side, oblique, tips distinctly united, 

 frequently with secondary intervening ones, reticulations quite 

 evident from beneath. Panicle terminal or from the upper- 

 most leaf axil, occasionally scattered along leafless short 

 branchlets; spikes usually in small groups, 3 to 5 or even 

 8 cm. long, yellowish green puberulent, divaricately rebranched; 

 pedicels similar in vestiture, averaging 3 mm. in length, 

 slender, subtended by minute caducous bracts; flowers easily 

 falling, possessing sour dough odor, pale sulphur yellow ex- 

 cept the grayish ovary and aurantiacus anthers, soft in tex- 

 ture; pedicel strict, 3 to 5 mm. long, finely hirsute; calyx 

 usually subtended by a pair of small puberulent bracts, sub- 

 glabrous or minutely puberulent, obscurely wrinkled in the 

 dry state, 5 mm. long and nearly as wide, saccate from the 

 base; lobes 5, obtusely triangular except the upper broad 

 one which is terminated by 2 obtusely rounded teeth, reticu- 

 lately veiny; petals 5, free, averaging 6.5 mm. long, in- 

 serted upon the thickened calyx base; the expanded ban- 

 ner broadly elliptic, rounded at apex, abruptly constricted 

 at the base, veiny, ventrally folded and merely at right angles 

 to others; wings oblong, also veiny, the basal one half slend- 

 erly clawed, as long as the banner, obtusely rounded at apex, 

 base truncate and with obscure hastate appendages; keels adnate 

 along the lamina, the slender claws free and as long as the 

 others; the stamineal fold 4 mm. long, straight along the 

 lower side, oblique, ascendingly curved, obtusely truncate at 

 apex, with a hyaline lobe at the truncate base, the upper 

 margin hyaline; stamens 9, all fertile, nearly as long as 

 the keels and included by them, forming a large tube, 

 glabrous; the free filamentous portion 0.33 mm. long, the 

 cells divergent at the apex; pistil 7.5 mm. long, the basal 

 one third stipitate and nearly glabrous toward the base, the
