疏花葶苈 shu hua ting li

Herbs perennial, 5-15 cm tall. Caudex several branched, ultimate branches subfiliform, terminated in rosettes. Stems decumbent, simple, basally sparsely pubescent with stalked, forked trichomes, distally with crisped, appressed, sessile or short-stalked, forked or 3-branched trichomes. Basal leaves rosulate, persistent; petiolelike base 2-15 mm; leaf blade broadly obovate, 0.5-1.7 cm × 3-8 mm, abaxially sparsely pilose with a mixture of long-stalked, forked and minutely 3- or 4-rayed stellate trichomes, adaxially with predominantly long-stalked forked trichomes, base cuneate to attenuate, margin 1- or 2-toothed on each side, sometimes subtrilobed and with the terminal lobe largest, apex subacute. Cauline leaves 5-10, similar to basal leaves in shape and indumentum, uppermost bracts entire, oblong. Racemes 2-6-flowered, bracteate throughout, elongated considerably in fruit. Fruiting pedicels 0.5-1.5 cm, strongly recurved or uppermost ascending, sparsely pubescent all around with appressed, subsessile, forked and 3-branched trichomes. Sepals oblong or ovate, 3-3.5 × ca. 1.5 mm, spreading, abaxially pilose with simple trichomes, not saccate, margin membranous. Petals yellow, broadly obovate, 6-8 × 3-4 mm, spreading, apex emarginate; claw 2-3 mm. Filaments 3.5-5 mm, spreading; anthers oblong, 0.7-1 mm. Ovules 18-22 per ovary. Fruit suborbicular, ovate to oblong, 0.7-1.3 cm × 3-6 mm, pendulous, latiseptate, not twisted; valves puberulent with simple trichomes and fewer, forked trichomes, obscurely veined; style 2-3.5 mm. Seeds brown, ovate, 1.2-1.5 × 0.9-1.1 mm. Fl. and fr. Aug.

* Rocky crevices; ca. 4600 m. Sichuan.

Draba remotiflora is known only from the type collection, Harry Smith 3474 (holotype, UPS; isotypes, B, BM, E, K, W). It is readily distinguished from all other Chinese species by having lax, few-flowered racemes, spreading floral parts, pendulous, pilose fruits on strongly recurved, lowermost pedicels, and long styles 2-3.5 mm.
