Cauline leaves absent or 1 or 2(or 3), sessile; leaf blade ovate to oblong, 2-9 × 1-3 mm, pubescent as basal leaves, base obtuse, margin entire or 1-3-toothed, apex acute.

Draba ussuriensis is very rare in China and is known to the present authors from a few collections made primarily in Changbai Shan, including Hong et al. 32754 (PE). The record in FRPS of D. ussuriensis from China is probably based on misidentified plants of D. mongolica.
