Herbs annual or biennial, (10-)25-60(-70) cm tall, with a few sparse glands and appearing eglandular, glabrous throughout except for sepals and sometimes stems. Stems erect, simple below, branched above, glabrous throughout or rarely sparsely hirsute with simple trichomes. Basal leaves withered by flow-ering. Middle cauline leaves with petioles (2-)5-15(-30) cm; leaf blade elliptic, (0.9-)1.7-4.5(-8) × (0.2-)0.5-1.8(-3) cm, margin coarsely serrate, apex acute. Fruiting pedicels divaricate-ascending, 4-10 mm, glabrous. Sepals 4-6 × ca. 1.5 mm, densely hirsute distally. Petals purple, obovate, 1-1.7 cm × 4-5 mm; claw 6-8 mm. Filaments 4-8 mm; anthers narrowly oblong, 1.4-1.8 mm. Fruit erect, (3.5-)4.5-7(-8.5) cm × ca. 1.5 mm, glabrous; style 1-2 mm. Seeds 1.2-1.5 × 0.8-1 mm; wing distal, ca. 0.3 mm wide. Fl. and fr. May-Aug.
Mountain slopes; 1100-1700 m. Hebei, Jilin, Nei Mongol, Shandong, Shanxi [Korea, Mongolia].
Clausia trichosepala was treated in FRPS under Hesperis. However, the species has multicellular glands on multicellular, multiseriate stalks, a feature that clearly supports its exclusion from Hesperis. The glands in Hesperis are unicellular on few-celled, uniseriate stalks.
