Herbs perennial, (4-)10-20(-30) cm tall; caudex several branched, covered with petiolar remains of previous years. Trichomes malpighiaceous, rarely a few 3-fid on leaves adaxially. Stems 1 to several from base, leafy. Basal leaves rosulate; petiole (1-)2-5(-8) cm; leaf blade elliptic, oblong, oblong-ovate, spatulate, or oblanceolate-linear, (0.6-)1.5-6(-10) × 0.5-1.5(-2) cm, base attenuate, margin coarsely dentate or rarely denticulate, apex acute.
Racemes corymbose, slightly elongated in fruit, bracteate throughout. Fruiting pedicels divaricate, 3-7(-20) mm, stout, narrower than fruit, straight. Sepals oblong-linear, 7-10(-12) mm, caducous, lateral pair strongly saccate. Petals yellow, broadly obovate or suborbicular, (1.4-)1.7-2(-2.5) cm × (6-)7-9 mm; claw usually longer than sepals. Filaments 0.8-1.3 cm; anthers oblong-linear, 2.5-3.5 mm. Ovules 14-24 per ovary.
Fruit linear, flattened, (3.2-)4-8(-9) cm × 4-5 mm, not torulose, slightly curved; valves not keeled, with a distinct midvein, outside with malpighiaceous trichomes, inside glabrous; style 1-2 mm; stigma capitate, entire. Seeds oblong, 3-4.5 × 1.5-2.5 mm, on stout funicles. Fl. May-Jul, fr. Jul-Oct.
- Limestone slopes, gravelly slopes, glacial gravel, pastures; 3600-4900 m. Yunnan.
The type collection of Erysimum schneideri, Schneider 3292 (holotype, B; isotypes, G, GH, K), is indistinguishable from that of Parrya forrestii, Forrest 6518 (holotype, E). In FRPS and Fl. Yunnan. (6: 102, 106. 1995) the two names were treated under Erysimum and Cheiranthus, respectively.
