Herbs perennial, (7-)10-45(-82) cm tall, not canescent. Caudex branches many, surculose, terminated in rosettes. Stems erect or decumbent, simple, sparsely or rarely densely pubescent with a mixture of simple and sessile stellate trichomes, apically tomentose with appressed stellate ones. Basal leaves rosulate, persistent, sessile, oblanceolate to obovate or oblong, 1-4 cm × 3-7 mm, abaxially sparsely pubescent with stalked, 3-or 4-rayed stellate trichomes, sometimes glabrescent except for margin and midvein, adaxially with a mixture of primarily simple trichomes and fewer stellate ones, rarely exclusively simple, base cuneate, margin dentate or entire, apex obtuse. Cauline leaves (3-)7-17(-30), sessile; leaf blade oblong, lanceolate, or ovate, 1.5-5(-8) × 0.5-1.5 cm, pubescent as basal leaves, base obtuse, often auriculate or amplexicaul, margin dentate or entire, apex obtuse or acute. Racemes (12-)20-60(-120)-flowered, bracteate basally or to near apex, elongated considerably in fruit. Fruiting pedicels (0.5-)1-2.2(-2.7) cm, divaricate, straight or curved upward, glabrous adaxially, pubescent abaxially with appressed stellate trichomes. Sepals oblong or ovate, 2-3(-3.5) × 1-1.5(-2) mm, ascending, abaxially sparsely pilose with primarily simple trichomes, base of lateral pair subsaccate, margin membranous. Petals yellow, obovate, 5-8 × (2-)2.5-4 mm, apex emarginate; claw 1-2 mm. Filaments 2-3.5 mm; anthers oblong, 0.6-0.9 mm. Ovules 8-12 per ovary. Fruit oblong, elliptic, or elliptic-linear, (0.7-)1-1.5(-2) cm × 3-5 mm, latiseptate, sometimes slightly twisted; valves glabrous, with a distinct midvein extending full length; style 0.5-1.5 mm.
