Plants 5-10 cm tall, acaulescent to shortly caulescent, caespitose. Stems, if present, up to 5 cm, densely covered with ± medifixed, appressed to subappressed, white hairs up to 1 mm. Leaves 2.5-8 cm; stipules 3-5 mm, mostly ± appressed hairy; petiole 1-3 cm, like rachis rather densely covered with appressed to partly ascending, mostly ± medifixed hairs; leaf-lets in 4-7 pairs, 4-8 × 1-3 mm, adaxially glabrous or with scat-tered hairs along margins, abaxially densely to rather densely covered with subappressed to spreading hairs. Racemes 2-5-flowered; peduncle 2-6 cm, with appressed to ascending hairs; bracts ca. 1.5 mm, predominantly white hairy.
