standard shorter than wings, plaited, thick and more or less tapering 
and bearing inflexed auriculate appendages at base; wings oblong or 
obovate, curved, usually adhering to keel, broadly 1-auriculate at base ; 
keel about equal to or often larger than wings, 2-auriculate at base, 
curved acute or cartilaginous beaked at apex. Stamens 10, 2-adelphous 
(9-1); 5 alternipetalous anthers longer subbasifixed; oppositi- 
petalous shorter, often bearded, versatile. Germen sessile villous; 
ovules few descending subanatropous; raphe short thick ; micropyle 
extrorse superior ; style slender often corrugated in bud, beardless ; 
apex minutely capitate, stigmatiferous. Legume often large thick 
ovate, oblong, or linear, usually covered outside with stinging hairs 
and sometimes variably ribbed or laminated,’ stuffed or spuriously 
septate within between seeds, 2-valved, seeds orbicular or transversely 
oblong, compressed ; hilum sometimes short, sometimes linear and 
half or more than half surrounding seed, exarillate; embryo thick. 
——Herbs or shrubs, climbing or more rarely suberect; leaves of 
Phaseolus ; stipules deciduous ; flowers’ racemose ; racemes sometimes 
short subcymose, oftener elongated and composed of alternate 
fascicles ; bracts small, often caducous (All hotter regions’).

beardless ; stigma terminal. Legume linear falcate 2-valved. Seeds 
exarillate.—T wining herbs ; leaves pinnate 3—6-7-foliolate stipellate ;

1 From which character the genus is divided 
into three sections—viz.: 1. Citta. Legume 
laminated, with transverse foliaceous folds.—2. 
Stizolobium. Legume linear, longitudinally 
ribbed or bare.—3. Carpopogon. Legume 
longitudinally ribbed or winged at sutures, con- 
stricted between seeds.
