Characteristics

Perennial herb or suffrutex 200-600 mm tall. Stems 1-15, clothed in short white hairs with longer hairs interspersed. Rootstock with long stylopodium, thin and beaded when young, becoming wavy or constricted but finally daucate when mature. Leaves trifoliolate, basal leaves usually unifoliolate, 45-60 x 20-30 mm; laterals smaller, less symmetrical, elliptic to narrowly obovate, if unifoliolate then obovate, apex subacute, base cuneate; sparsely pubescent above, densely woolly below with veins prominent due to dense covering of longer appressed hairs, glandular. Stipules 8-14 mm long, free. Racemes axillary, (8-)25-35-flowered, overtopping the subtending leaves. Flowers 6-7 mm long, up to 3 mm wide, orange with red veins or yellow-orange; bracts 4-6 mm long, rapidly caducous. Calyx 4 mm long, tube 2 mm long; keel lobe up to 3.5 mm long, teeth triangular. Standard 6-10 x 6 mm, emarginate with well developed downward curving auricles, clawed; back hairy and glandular; appendages present, fused, extending from auricle to auricle just above the apex of the claw. Wing petals 8-9 x 2.0-2.75 mm, auriculate, upcurving, longer than keel. Keel petals 6-7 mm long, up to 3-4 mm wide, pouched, gland-dotted. Staminal sheath 6 mm long; tenth stamen free. Pistil 6-7 mm long; ovary 2.5 mm long, densely hairy; style thickest at point of flexure, hairy for f its length, height of curvature 2 mm. Nectary present, 0.2-0.3 mm high, margin wavy.
