Low bushy herb or small shrub, up to 20–80 cm tall, with a well developed system of branches covered in a tomentum of short ± appressed to long fine mostly spreading hairs.
Pod practically sessile, 5–7 mm long, shortly ovoid-ellipsoid to oblong-ellipsoid, pilose outside and also inside at least along the lower suture, 2–4-seeded.
Calyx 4.5–6 mm long, densely hairy; lobes narrowly attenuate-triangular to oblong-triangular, c. 3 times as long as the tube.
