Herbs perennial, 7-45 cm tall, cespitose, canescent at least basally. Caudex branched. Stems erect, much branched above, densely pubescent with a mixture of simple and sessile stellate trichomes, apically tomentose with appressed stellate ones rarely with fewer simple trichomes. Basal leaves rosulate, sessile, oblong-linear to narrowly oblanceolate, 3-6 cm × 2-4 mm, abaxially densely pubescent with subsessile, 5-8-rayed stellate trichomes, adaxially with a mixture of primarily simple trichomes and fewer stellate ones, rarely exclusively simple, base attenuate, margin entire, apex obtuse. Cauline leaves 3-20, sessile; leaf blade ovate, oblong, or lanceolate, 1-5 cm × 3-7 mm, pubescent as basal leaves, base auriculate or amplexicaul, margin entire, apex obtuse. Racemes (20-)30-90-flowered, ebracteate, elongated considerably in fruit. Fruiting pedicels 3-15 mm, divaricate, straight or slightly curved, glabrous adaxially, pubescent abaxially with stellate trichomes. Sepals oblong or ovate, (2-)2.5-3.5 × 1-1.5 mm, ascending, abaxially sparsely pilose with primarily simple trichomes, base of lateral pair subsaccate, margin membranous. Petals yellow, obovate, (4.5-)5-7 × 2.5-4 mm, apex emarginate; claw 1-2 mm. Filaments 1.5-4 mm; anthers ovate, 0.4-0.6 mm. Ovules 6-12 per ovary. Fruit oblong to linear-elliptic, 4-10 × 2-4 mm, latiseptate, not twisted; valves densely pilose with simple, forked, or stellate trichomes, sometimes sparsely pilose only near fruit base; style 0.5-1.5 mm.
