Perennials; caudex simple or branched, (woody); densely (silvery) pubescent, trichomes (short-stalked), 4-8-rayed, rays furcate or bifurcate, (finely tuberculate throughout). Stems simple or few from base, decumbent, (straggling and flexuous, usually branched distally), 4-8 dm. Basal leaves: blade narrowly elliptic to oblanceolate, 4-12 cm, margins entire, sinuate, or shallowly dentate, (apex acute). Cauline leaves (sessile or proximal shortly petiolate); blade linear to narrowly elliptic, 3-4 cm, margins entire, sinuate, or remotely dentate, (apex acute). Racemes loose, (sometimes greatly elongated). Fruiting pedicels (recurved), 15-20(-25) mm. Flowers: sepals elliptic, 3.5-4 mm, (lateral pair subsaccate, median pair thickened apically, cucullate); petals broadly obovate, 4-5 mm, (sometimes with short, broad claw). Fruits (pendent), subglobose or broadly ovoid, slightly compressed, 5-7 mm; valves (not retaining seeds after dehiscence), glabrous throughout; ovules per ovary unknown; style 1.5-2 mm.
