Leaves 1-foliate; petiole 4-5(-14) mm long, glabrous or pubescent, leaf blades variable, 1-3 cm x 1 cm on lower stem and up to 6.5 cm x 1-2 cm on upper stem; leaf blade often ovate-oblong or oblong-lanceolate to lanceolate, elliptic, cordate or nearly orbicular, glabrous except on nerves beneath, lateral nerves 4-5 pairs, reticulate veinlets prominent on both surfaces. Racemes axillary or terminal, 1.5-7 cm long, laxly flowered bearing 6-12 flowers, binate (in pairs) at each node, internodes 2-5 mm. Bracts scarious, ovate with acuminate apex. Flowers bisexual, zygomorphic, 5-merous, perigynous, 4-5 mm long, red, reddish purple or purplish blue. Pedicel 1.5-2 mm, pubescent. Calyx 5, fused, 3-4 mm long, 5-toothed, 2 upper lobes nearly fused excepting apex, teeth linear, acute, pubescent without. Corolla 5, papilionaceous, red, reddish purple or purplish blue, 6-7 mm long; vexillum broad, obovate (or nearly orbicular), apex emarginate; keel obtuse adherent to wings. Stamens 10, diadelphous (9+1), vexillary stamen free, staminal tube 6-7 mm long, anthers uniform. Ovary nearly sessile, 4-4.5 mm long, oblong, pubescent or villous, unilocular, 4-8-ovuled, placentation marginal; style 3-4 mm long, linear, incurved; stigma capitate.
