    Herbs, subshrubs, or shrubs, prostrate or scrambling to erect. Leaves 1-3 (or rarely-5)-foliolate, petiolate, stipulate; leaflets petiolulate and stipellate. In- florescences axillary or terminal, racemose or racemose paniculate, or extremely dense and capitate; primary bracts striate and ciliate, each subtending 1 (pedi- cellate) flower, or a fascicle of 2 to several flowers; secondary bracts often pres- ent, similar to the primary bracts or depauperate, each subtending a single flower; bracteoles rarely if ever present in American species. Flowers pedicellate, pap- ilionaceous, calyx 2-lobed, the upper lobe almost entire to bifid, the lower 3- toothed with the central tooth longer than the laterals, or the calyx almost equally 5-lobed; corolla exceeding the calyx, the standard slightly clawed, wings some- what so, wings often attached to keel petals by a small appendage, keel petals long clawed, partially fused above; vexillary stamen free or partially fused; an- thers uniform; ovary sessile or stipitate, ovules 2-many, the style slender, the stigma terminal. Fruit lomentaceous, i.e., transversely septate and forming (1-)2- many articles, usually stipitate, indehiscent, or tardily dehiscent, or in 1 species in Panama the walls between the sutures falling away leaving the sutures as a frame; articles variously shaped from nearly linear to almost saccate or circular and notched at the apex, sometimes folded on each other in accordion fashion (at least when young), the surfaces glabrous to densely pubescent with straight tapering or hooked trichomes, or these only on sutures, the articles 1-seeded. Seeds oblong or subquadrate to reniform.

    Herbs, subshrubs, or shrubs. Leaves pinnately 3-foliolate or 1-foliolate by reduction of lateral leaflets, stipulate, stipellate. Flow­ers usually smaller, in racemes or panicles, axillary or terminal, rarely solitary or binate in leaf axils. Bracts persistent or early decid­uous; bracteoles present or absent. Calyx campanulate, 4- or 5-lobed, bilabiate; upper 2 lobes connate for all or most of length, entire or 2-toothed at apex, lower lobes free, longest. Corolla white, green-white, pink, purple, or violet; standard elliptic or obovate to nearly orbicular; wings ± adherent to keel, wholly clawed. Stamens diadelphous (9+1), rarely monadelphous.
