Primary racemes short, few-flowered, most of the flowers on lateral branches progressively abbreviated upwards and in the axils, forming a leafy pseudopanicle; bracts 0.5–1.5 mm long, linear-subulate; bracteoles usually on the pedicel, setaceous.
Standard elliptic-obovate to broadly elliptic, yellow tinged red, sparsely hairy outside; wings equalling the keel or shorter; keel 9–11 mm long, angular, with a narrow twisted beak incurved at the tip.
Stems several from a woody rootstock, erect to 60 cm, developing numerous progressively shortened flowering branches above, ribbed, densely strigulose.
Calyx 4–5 mm long, densely strigulose; lobes triangular, somewhat acuminate or attenuate, 1.5–2 times as long as the tube.
