Plants (3-)8-20(-25) cm tall, cespitose, glandular or eglandular, sparsely to densely pubescent with simple trichomes to 1.5 mm; caudex branched, covered with petiolar remains of previous years. Basal leaves rosulate; petiole broadened at base, ciliate or not, (0.5-)1-4(-6) cm; leaf blade lanceolate or linear in outline, all or at least some pinnatifid or pinnatisect and with 3-9 lobes on each side, 1.5-7 × (0.3-)0.6-2 cm, pubescent or glabrous, base cuneate or attenuate, apex acute; lateral lobes oblong, linear, or rarely ovate, 2-10 × 0.5-3 mm, entire. Cauline leaves absent. Racemes 2-10-flowered. Fruiting pedicels ascending or divaricate, glandular or eglandular, (0.4-)1-2.5 cm. Sepals purple, linear or linear-oblong, 6-10 × 1.5-3 mm, glabrous, pubescent, or glandular, white margined. Petals purple or lavender, rarely white, broadly obovate, (1.3-)1.5-2(-2.2) cm × 4-8 mm, apex emarginate; claw 0.8-1.2 cm. Filaments purple or white, median pairs 6-8 mm, lateral pair 3-5 mm; anthers linear, 3-4 mm. Ovules 16-40 per ovary. Fruit linear to linear-lanceolate, (2-)3-8(-10) cm × 2-2.5(-3) mm; valve margin flat; replum flattened; style (1.5-)2.5-6 mm; stigma 1-2 mm. Seeds broadly oblong, 3-5 × 2-3.5 mm, flattened, broadly winged; wing 0.5-1 mm wide. Fl. May-Jul, fr. Jul-Aug.

Marble scree, stony slopes, gravel; 1600-4400 m. Xinjiang [Afghanistan, Kashmir, Kazakhstan, Kyrgyzstan, Pakistan, Tajikistan].

The records of Parrya pinnatifida in FRPS and Fl. Xizang. (2: 384. 1985) were based on misidentified plants of P. nudicaulis. The records of P. subsiliquosa Popov in FRPS and Fl. Xinjiang. (2(2): 176. 1995) were based on misidentified plants of P. beketovii and P. pinnatifida. The present authors have seen no Chinese material of P. subsiliquosa, which is endemic to Kyrgyzstan and neighboring Kazakhstan. It is likely to be conspecific with P. longicarpa Krassnov, a species with fruit terete to subquadrangular, narrowly linear, and 1.5-2 mm wide and seeds oblong and narrowly winged. The occurrence of P. pinnatifida in China is here confirmed based on Cheo Taiyien 650883 (HNWP, NAS).

Parrya pinnatifida var. hirsuta N. Busch and var. glabra N. Busch were accepted in FRPS, but both varieties are invalidly named (they are nomina nuda); they are anyway only minor variants and do not merit recognition.
