Draba parviflora (Regel) O. E. Schulz in Engler, Pflanzenr. 89(IV. 105): 273. 1927. D. hirta Linnaeus var. leiocarpa Regel f. parviflora Regel, Nouv. Mém. Soc. Imp. Naturalistes Moscou 11: 51. 1859. TYPE: without locality, Regel s.n. (lectotype to be designated by Al-Shehbaz, LE!). No specimens were cited in the original publication. Of the three sheets at LE that can be designated as lectotypes, only two, carry Regel’s handwriting. The one with flowers and mature fruits is selected here. A fourth sheet at LE collected by Semenov and with the same Regel’s annotation is definitely D. lasiophylla.
