Plants forming bushy clumps, subacaulescent or shortly cau­lescent, 15–65 cm, strigulose. Stems erect or ascending, strig­ulose. Leaves mostly in sub-basal cluster, (6–)10–30 cm; stipules connate-sheathing at proximal nodes, mostly connate at distal nodes, 3–10(–11) mm, scarious throughout; leaflets (9–)13–25(–31), blades linear-oblong, linear-elliptic, lanceolate, or subfiliform, 3–23 mm, apex obtuse, acute, or retuse, surfaces sparsely strigulose abaxially, usually glabrous adaxially; terminal leaflet sometimes continuous with rachis. Peduncles erect, sometimes divergent in fruit, 5–33 cm, together with racemes longer than stems. Racemes 7–20-flowered, flowers ascending to spreading; axis (3–)4–13(–15) cm in fruit; bracts 2–4.5 mm; bracteoles 2. Pedicels 1–4.5 mm. Flowers 15–25.5 mm; calyx campanulate, cylindric, or sub­cylindric, 7–12 mm, strigulose-pilosulous, tube 4.9–9.2 mm, lobes subulate, 1.3–3(–4) mm; corolla whitish with keel tip purple, sometimes banner and wings also purple-tipped, sometimes purple throughout; banner recurved through 30–45°, oblanceolate or broadly rhombic-oblanceolate, 16–25.5 mm, apex emarginate; keel 11.6–17.5 mm. Legumes stramineous, straight or slightly incurved, oblong-ellipsoid to narrowly oblong-ovoid, obcompressed, 12–25 × 4.3–8 mm, sub-bilocular, fleshy becoming leathery or subligneous, glabrous or strigulose; septum to 1.4 mm wide; sessile. Seeds 15–30.
