Rootstock carrot-shaped, at length woody. Stem erect in youth, twining at length, somewhat ridged to alate, scarcely strigose to patent with light hairs. Leaflets oblong with apex and base rounded in juvenile stage, ±25-58 x 0.8-30.0 mm, surface smooth to touch, adnately strigose, thickest along dorsal nerves and lamina margin, rhomboid to sublobular with rounded lobes at maturity, ±80 x 60-70 mm at broadest point, apices abruptly narrowed, obtuse, apiculate, base cuneate to obtuse, papyraceous, strigose. Stipules with cordate base, laterally auriculate at maturity, lanceolate, reflexed, ±6.0 x 1.5 mm, acuminate, margins ciliate; in youth base more or less elongated, truncate (cf. V. mudenia B.J. Pienaar). Inflorescence contracted, peduncles alate, bearing at apex one pair of yellowish green flowers, flushed violet, with vertical row of extrafloral nectary glands between them. Calyx campanulate, lobes, ±2 mm, acute with broad bases, + as long as tube or shorter, tube up to 3.25 mm long, upper pair of lobes connate for li3 to li2 their length, strigose. Standard ovate to oblate, emarginate, ±10-14 mm long, spur straight with inferior callosities divergent, auricular, superior callosities divergent, narrow (vestigial). Wings narrowly ovate, ±10.0 x 5.5 mm, auricle slender with raised cell sculpturing (almost papillate). Keel ±11 mm long, obtuse, slightly upturned. Filament tube ±10 mm long, free filaments in two whorls, 3 or 4 mm long, anterior filament geniculate at base, ±13 mm long; anthers oblate, glands at base absent Ovary pubescent, ±9-10 mm long, style broadened and flattened as it curves upward, pollen brush on anterior face, apically twisted at maturity, accentuated protuberance of style prolongation absent but stylar tissue swollen as it bends toward stigmatic papillae at somewhat more than 90°. Pollen grains scarcely reticulate, muri low, rounded. Legumes beaked, ±68 mm long, scabrid with long, stiff hairs along margin, 18-seeded. Seeds 3.4 mm long, yellowish brown to dark brown, black mottled around hilum, hilum scarcely eccentric, aril scarcely developed or absent.
