Malcolmia hispida Litw.

刚毛涩荠

Description from Flora of China

Fedtschenkoa hispida (Litvinov) Dvorák; Strigosella hispida (Litvinov) Botschantzev.

Herbs annual, (5-)10-30 cm tall, densely hispid basally with exclusively simple trichomes to 3 mm, these mixed on other parts with much smaller, short-stalked, forked trichomes. Basal leaves not rosulate. Middle and lower cauline leaves petiolate; petiole 0.5-2 cm; leaf blade oblong, oblong-lanceolate, or linear-lanceolate, 2-5 cm × 3-8 mm, base attenuate or cuneate, margin entire or sparsely denticulate, apex obtuse; midvein whitish and thickened; uppermost leaves smaller and subsessile. Racemes several to many flowered, elongated considerably in fruit; rachis straight. Fruiting pedicels thickened, as wide as fruit, 0.5-1.5 mm. Sepals 3.5-4 × 0.5-0.7 mm, persistent. Petals pink, linear, 8-10 × 0.8-1 mm. Filaments free or median pairs connate near base, 2.5-4 mm; anthers narrowly oblong, 0.7-1 mm. Fruit linear, straight, latiseptate, strongly torulose, 4-6 cm × 1-1.7 mm; valves not veined, densely pubescent with setose simple trichomes mixed with much smaller, forked and subdendritic ones; style obsolete; stigma conical, to 1 mm. Seeds oblong, 1.2-1.5 × 0.6-0.8 mm. Fl. Apr-Jun, fr. May-Jul.

This species was recorded in FRPS from Gansu, Qinghai, and Xinjiang, but the present authors have seen no material from those provinces and autonomous region. It is likely that the records were based on misidentified plants of Malcolmia africana that have some simple trichomes on the fruit. The above record from Xizang is based on Chaffanjon 207 (P).

Foothills; 1900-2000. Xizang [Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan].
