Plants perennial, covered with hairs partly basifixed, partly with a very short subbasal acute appendix and therefore extremely asymmetrically medifixed. Stipules minute, very shortly to shortly adnate to petiole, otherwise free. Racemes pedunculate, loose to rather dense. Flowers with short pedicels. Calyx campanulate. Standard widely and deeply incised; limbs of wings rounded at apex. Stigma glabrous or with minute hairlets. Legumes (unknown in Chinese species) linear, curved, keeled ventrally, grooved dorsally, 1-locular or 2-locular; valves thin.

Seven species: Afghanistan, China, India, Pakistan, Tajikistan; one species (endemic) in China.
