Description from Flora of China
Draba incana Linnaeus var. flaccida Maximowicz; D. incana var. microphylla W. W. Smith; D. lanceolata Royle var. chingii O. E. Schulz; D. lanceolata var. latifolia O. E. Schulz.
Herbs perennial, (7-)15-45(-60) cm tall, cespitose. Caudex slender, few branched, ultimate branches terminated in rosettes, covered with petiolar remains of previous years. Stems erect, simple or rarely branched above middle, sparsely to densely pubescent with subsessile stellate trichomes, often glabrescent distally. Basal leaves rosulate, persistent; petiole 5-10(-15) mm, sometimes undifferentiated; leaf blade elliptic, oblong, or lanceolate, (0.3-)1-2.5(-4) cm × (1-)2-7(-10) mm, abaxially pubescent with sessile or short-stalked, 4-rayed stellate trichomes 1 or 2 rays of which often branched, adaxially pubescent with similar stellate trichomes or with a mixture of stellate and simple ones, base attenuate to cuneate, margin entire or denticulate, apex acute. Cauline leaves (4-)6-19(-26), sessile; leaf blade ovate, oblong, or elliptic, 0.4-2.5(-4) cm × 1.5-7(-15) mm, pubescent as basal leaves or adaxially strigose with simple trichomes, base cuneate to obtuse, margin entire or 1-4(-7)-toothed on each side, apex acute. Racemes (8-)14-35(-45)-flowered, bracteate basally, not elongated in fruit. Fruiting pedicels 2-10(-12) mm, divaricate, straight, glabrous or pubescent all around with subsessile, forked or stellate trichomes sometimes mixed with simple ones. Sepals oblong or ovate, 1-1.5 × 0.5-0.6 mm, erect, abaxially pilose with simple trichomes, base of lateral pair not saccate, margin membranous. Petals white, broadly spatulate, 2-3 × 0.8-1.1 mm, apex emarginate; claw absent. Filaments 0.9-2 mm; anthers ovate, 0.2-0.3 mm. Ovules (28-)32-52(-60) per ovary. Fruit linear, (5-)7-12(-17) × 1-1.5 mm, erect or rarely divaricate, latiseptate, rarely slightly twisted; valves glabrous, base and apex obtuse, with a distinct midvein; style obsolete, rarely to 0.1 mm. Seeds brown, ovate, 0.6-0.8 × 0.4-0.5 mm. Fl. and fr. Jun-Aug.
Except for not having fully mature fruits, the type collection of Draba lanceolata var. chingii, R. C. Ching 497 (holotype, B; isotypes, E, GH, P, PE, US), is indistinguishable from that of D. ladyginii, Ladygin 381 (holotype, LE; photos, MO, PE).
