 9 to 13 cm long, subterete, curved and somewhat thickened 

 at the ba^e, subpersistent; petiolule darker green, 5 to 7 mm 

 long, thick, grooved along the upper side, curing yellowish, 

 articulate at the base and easily separating at that point, 

 the petiole extended 6 mm above the lateral pair of leaf- 

 lets; blades trifoliate, subcoriaceous, curing greenish to brown 

 on both sides, entire, 10 to 14 cm long by one half as 

 wide relatively; lateral pair very unequilateral, abruptly 

 acute at the apex, base truncately rounded; the terminal 

 leaflet symmetric, similar at the apex, broadly cuneate toward 

 and at the basil point rounded; midrib glabrous, pronounc- 

 ed beneath, stramineus when dry, finely ridged along the 

 upper side; lateral nerves 5 to 7 pairs, similar in prominence 

 and color, ascending, nearly straight, tips strongly curved, 

 basal pair of the terminal leaflet parallel with the edge of 

 the leaf, cross bars evident, reticulations minute; stipules 

 adnate, thick, oblongish, 5 mm long. Inflorescence lateral, 

 divaricate; rigid spikes 5 to 20 cm long, subterete, glabrate, 

 more or less striate and short bracteate at the base, flower 

 bearing above the middle; very young apical bud bracts 

 oval, strongly ridged; flowers 3 to 5-clustered from 3 to 5 

 mm long stout branchlets, odorless, deciduous, atrocyanens 

 especially the calyx; buds subterete, nearly straight, upon 

 slender glabrous 1 cm long pedicels; calyx 7 mm long, 

 5 mm wide across the truncate top, somewhat narrowed at 

 the base, subterete, glabrous, with many parallel purple 

 veins which toward the top is cross nerved; banner 3 cm 

 long, broadly lanceolate, 1 cm wide across the middle, apex 

 rounded, ba9al portion gradually clawed, sides more or less 

 folded upon the ventral side and rugose below the middle, 

 erect or reflexed from below the middle, glabrous, every part 

 of it conspicuously streaked with purple; wings 1.75 cm long,
