Erysimum absconditum O. E. Schulz; E. chamaephyton Maximowicz.
Herbs perennial, (1.5-)2-6(-8) cm tall; caudex several branched, covered with petiolar remains of previous years. Trichomes malpighiaceous, very rarely with a few 3-forked ones on leaves adaxially. Stems 1 to several from base, leafless or few leaved. Basal leaves rosulate; petiole (0.2-)0.5-2 cm; leaf blade oblong-linear or oblanceolate-linear, (0.4-)1-4 cm × 1.5-3.5(-5) mm, base attenuate, margin entire or rarely denticulate, apex acute. Racemes corymbose, not elongated or only slightly elongated in fruit, ebracteate or only lowermost flowers bracteate. Fruiting pedicels divaricate, (3-)4-7(-10) mm, stout, narrower than fruit, straight. Sepals narrowly oblong, 5-6.5 mm, sometimes persistent, lateral pair saccate. Petals pink, narrowly spatulate, 7-9(-10) × 1.7-2(-2.5) mm; claw subequaling sepals. Filaments 4-6 mm; anthers oblong, 1-1.4 mm. Ovules (12-)16-30 per ovary. Fruit oblong-linear, 4-angled, (1-)1.5-2(-2.3) cm × 2.5-3 mm, not torulose, slightly curved; valves slightly keeled, with a prominent midvein, outside with malpighiaceous trichomes, inside glabrous; style 0.5-1 mm; stigma prominently 2-lobed, lobes subdecurrent Seeds ovoid-oblong, 1.5-2 × 0.8-1 mm, on filiform funicles to 6 mm. Fl. Jun-Jul, fr. Jul-Aug.
Rocky slopes, grassy areas, alpine meadows, stone beaches; 3400-5500 m. Gansu, Qinghai, Xizang [Sikkim].
Although Erysimum absconditum was described in 1931 from a specimen collected in Xizang, the name was not listed in FRPS or Fl. Xizang. (vol. 2. 1985). Both floras recognized E. chamaephyton, but the type of this name is indistinguishable in every aspect from that of E. funiculosum, which was previously considered to be endemic to Sikkim.
