Short-lived perennials, from a crown not woody; stems simple from each caudex branch, 20-63 cm tall, pubescence dense near base with short-stalked trichomes, 3-8-rayed, to 0.3 mm, pubescence similar towards ends of stems.

Basal leaves oblanceolate to narrowly oblanceolate, 1.5-5 mm broad, margins typically toothed, not ciliate, densely pubescent above and beneath with 5-12-rayed trichomes on short-stalks and up to 0.2 mm; cauline leaves 7-45, hiding the stem near base, lobe-like appendages at base absent or 0.7-3 mm, surfaces pubescent towards ends of stems.

Inflorescence usually 10-40-flowered, typically unbranched racemes; fruiting pedicels pendent, curving downward towards ends to horizontally spreading to ascending at base, 4-10 mm, pubescent with trichomes appressed and branched, occasionally slightly secund; flowers ascending to descending; sepals 4, pubescent; petals 4, white to pale purple, 5-9 mm long and 0.8-1.8 mm broad, glabrous; pollen ellipsoid.

Siliques 3-6.5 cm long and 1.9-2.2 mm broad, closely pendent, uncommonly appressed to rachis, generally not curved, with parallel edges; valves pubescent; seeds in 1 series, 1.4-1.8 mm long and 1-1.4 mm broad, with a continuous wing to 0.3 mm broad.
