Draba yunnanensis var. gracilipes Franchet; D. yunnanensis var. latifolia O. E. Schulz; D. yunnanensis var. microcarpa O. E. Schulz.
Herbs perennial, (5-)10-35(-60) cm tall, cespitose, canescent at least basally. Caudex simple or few to many branched, ultimate branches terminated in rosettes. Stems erect, simple, densely pubescent with a mixture of simple and sessile stellate trichomes, apically tomentose with appressed stellate ones. Basal leaves rosulate, persistent, sessile, oblong, oblong-linear, to narrowly oblanceolate, (0.5-)1-3.5(-5) cm × (1.5-)2-6(-8) 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 or stellate, base cuneate, margin entire, apex obtuse. Cauline leaves (4-)6-12(-18), sessile; leaf blade narrowly oblong, rarely lanceolate, (0.5-)1-3.8(-5) cm × 1.5-5(-8) mm, pubescent as basal leaves, base obtuse, not auriculate or amplexicaul, margin entire, apex obtuse. Racemes (12-)20-60(-80)-flowered, bracteate basally, elongated considerably in fruit. Fruiting pedicels (0.3-)0.5-1.5(-2) cm, divaricate, straight or slightly curved, glabrous adaxially, pubescent abaxially with 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, 5-7(-8) × 2-3(-4) mm, apex emarginate; claw 1-2 mm. Filaments 2-3.5 mm; anthers oblong, 0.5-0.9 mm. Ovules (4-)6-10(-12) per ovary. Fruit ovate, sometimes elliptic or suborbicular, 3-7(-10) × 2-3(-4) mm, latiseptate, sometimes slightly twisted; valves glabrous, obscurely to distinctly veined; style 0.4-1.2(-2) mm. Seeds brown, ovate, 1.4-1.9 × 0.9-1.4 mm. Fl. May-Jul, fr. Jun-Sep.
* Rock crevices, limestone scree, open Pinus-Quercus forests, grassy scrub, limestone cliffs; 2300-5500 m. Sichuan, Xizang, Yunnan.
