Characteristics

Plants 5-12 cm tall, acaulescent or nearly so, loosely to densely caespitose. Stems, if rarely present, up to 2-3(-6) cm, ascending, very densely covered with symmetrically to mostly strongly asymmetrically bifurcate, tangled, mostly spreading hairs of different lengths from 1-2 mm. Leaves (2-)5-12 cm; stipules 6-12 mm, adnate to petiole for ca. 2 mm, densely to very densely hairy like stem; petiole 2-4 cm, with rachis densely hairy like stem; leaflets in 7-13 pairs, narrowly elliptic, 2-13 × 1-4 mm, both surfaces very densely covered with ± symmetrically or asymmetrically bifurcate, subappressed to slightly ascending hairs 1-1.5 mm. Racemes several, crowded at base of leaves, subsessile or with a peduncle up to 2-6 cm, 2-4-flowered; bracts 7-10 mm, covered with asymmetrically bifurcate, subappressed to partly ± spreading, white hairs, apex sometimes with short black hairs. Calyx 10-12 mm, rather densely covered with strongly asymmetrically bifur­cate, tangled, ascending to partly spreading, white hairs 1.5-2 mm and, especially in upper part and at teeth, with mostly shorter black hairs, rarely without black hairs; teeth 2-3 mm. Petals whitish or pinkish or pale violet; standard oblong-pan­durate, 18-25(-28) × 7-8(-10) mm, scarcely to distinctly con­stricted below middle, apex retuse; wings 18-21(-25) mm; keel 14-19(-21) mm. Legumes sessile, 9-18 mm, 6-9 mm high and wide, acute, incompletely 2-locular; valves densely villous, with strongly asymmetrically bifurcate, ascending to spreading, tangled, white hairs ca. 2 mm.
