Annual herb from a taproot; stems 0.2-1.0 m tall, simple to (more commonly) loosely branched, stiff, usually strongly stiff-hairy with backward-pointing or spreading hairs.
Basal leaves oblanceolate, 4-25 cm long, 1-6 cm wide, pinnately-cut, terminal lobe the largest and more or less egg-shaped and shallowly round-toothed, glabrate to sparsely hairy; stem leaves usually unstalked, much reduced, generally with 4-6 linear to narrowly lanceolate lobes, terminal lobes more deltoid-lanceolate.
Racemes elongate in fruit, as much as 35 cm long; petals pale yellow, 3-4 mm long; sepals 1.5-2.5 mm long, oblong-oblanceolate.
Siliques, erect, 8-15 mm long, 1-1.5 mm wide, linear and awn-like, tightly appressed, beaked, sparsely hairy to glabrous; segments 3-nerved, tardily dehiscent; fruiting stalks erect, 1-3 mm long, stout, enlarged at the tips and about as thick as siliques; beaks 1-2 mm long; seeds about 1.3 mm long, plump, not gelatinous when wet.
