Basal leaves rosulate, subsessile; leaf blade oblong-obovate to subspatulate, 0.4-2 cm × 1.5-5 mm, abaxially densely subhirsute with long-stalked, forked or 3- or 4-rayed stellate trichomes with simple rays, sometimes with a few simple trichomes, adaxially with similar indumentum or with predominantly simple trichomes, base cuneate, margin entire, ciliate with simple trichomes to 1.3 mm, apex subobtuse. Cauline leaves absent, very rarely 1 at stem base. Racemes 4-16-flowered, ebracteate, elongated considerably in fruit; rachis sometimes slightly flexuous. Fruiting pedicels 3-9 mm, divaricate-ascending, slightly curved upward or straight, stout, glabrous or rarely sparsely pubescent. Sepals oblong, 0.9-1.5 × 0.6-0.8 mm, erect, abaxially sparsely pubescent with simple or stalked, forked trichomes, base of lateral pair not saccate, margin not membranous.
