Basal leaves rosulate; petiole 1-4 cm, usually ciliate, expanded at base; leaf blade oblanceolate or oblong, (1-)2-5(-8) cm × 3-7(-10) mm, glabrous or glandular, base cuneate, margin pinnatipartite, sinuate-dentate or entire, apex acute or obtuse. Cauline leaves absent. Flowers in racemes. Fruiting pedicels 3-10(-15) mm, glabrous. Sepals purplish, ovate, 3-4 × 1.5-2 mm. Petals purple, broadly obovate, 6-10 × 3-5 mm, obtuse at apex; claw 3.5-5 mm. Filaments 3-5 mm; anthers oblong, 1-1.5 mm. Fruit linear-cylindric, 1-1.5(-1.7) cm × ca. 2 mm, corky, strongly torulose, with 2-6 constrictions on each side, glabrous or glandular; style 1.5-3 mm. Seeds brown, oblong, ca. 1.3 × 1 mm. Fl. and fr. Jun-Jul.

Mountain slopes; 2900-4800 m. Xizang [India, Kashmir, Kazakhstan, Pakistan, Tajikistan, Uzbekistan].

Chorispora sabulosa and C. elegans were simultaneously published by Cambessèdes. Hooker and Thomson (J. Proc. Linn. Soc., Bot. 5: 181. 1861), who were the first to record the species from Xizang, listed the latter name as a synonym of C. sabulosa, which name therefore has priority under Art. 11.5 of the St. Louis Code. The species was not listed in FRPS or in Fl Xizang. (vol. 2. 1985), but the record from Xizang is here confirmed by the study of material cited by Hooker and Thomson (loc. cit.) and also by Jäschke s.n. (WU).
