6. HARPALYCE DC. Mem. Leg. 496. 1825; Prodr. 2: 523. 

 1825. 



Trees or shrubs, with alternate odd-pinnate leaves and small stipules. Leaflets entire- 

 margined, petioluled, sprinkled with yellow or orange sessile glands or gland-like scales 

 beneath. Flowers in racemes, either terminal or also in the upper axils, then forming small 

 leafy panicles; bracts and bractlets small. Calyx 2-lipped, the upper 2 and the lower 3 lobes 

 wholly united to the tip into two linear entire lips. Corolla papilionaceous; banner rounded, 

 broad, short-clawed or sessile; wings oblanceolate-falcate, short-clawed, with a deltoid basal 

 auricle on the upper side, or obovate and with a basal auricle on the upper and a more or less 

 developed median lobe on the lower; keel-petals lanceolate, falcate, in the Mexican species 

 equaling the banner and wings, strongly falcate, united above the middle but the obtuse 

 tips free, in the Cuban species much longer than the other petals and less curved. Stamens 

 monadelphous, the upper filament united with the rest at least half its length, but the staminal 

 tube split to the base; anthers alternately longer and shorter, in the Cuban species acute. 

 Ovary sessile, several or many-ovuled; style more or less strongly curved; stigma terminal. 

 Pod sessile, elongate, 2-valved, several-seeded, in some species (especially the Brazilian ones) 

 divided by spongious tissue between the seeds. 



Type species, Harpalyce formosa DC. 



Pod woody; leaflets broadest below the middle, pubescence not ferruginous. I. MexicanaU. 



Pod leathery; leaflets broadest at or above the middle; pubescence usually 

 more or less ferruginous. 

 Petals membranous; keel strongly incurved, shorter than or merely 



equaling the other petals; pod 1.5-2.5 cm. broad. II. FormosaE. 



Petals fleshy; keel slightly arched, at least half longer than the other 



petals; pod 1—1.5 cm. broad. III. CubEnsES.
