36. D. daurica DC. , Reg. Veg. Syst. Nat. 2: 350 (1821)

(D. hirta auct., vix L.).

More robust than the preceding species of this section; stems up to 25 cm, often flexuous, usually simple, stellate-canescent at least below, with (0-)l-4 cauline, toothed leaves. Basal leaves up to 2 cm, narrowly lanceolate, acute, entire or with 1-2 small teeth, ciliate and rather densely stellate-canescent. Inflorescence 8- to 20-flowered; pedicels suberect. Petals c. 5 mm, cream; filaments dilated at base. Silicula 6- 12 mm, glabrous (or more or less stellately hairy, var. hebecarpa Lindblad ), ovate-lanceolate, flat. 2« = 64. Arctic Europe and mountains o f Scandinavia. Fe Is No Rs (N) Sb Su. A very variable species, variously treated by different authors. It may be conspecific with D. glabella Pursh , Fl. Amer. Sept. 2: 434 (1814) from North America. The endemic taxa in Austria D. norica Widder , Sitz.-Ber. Akad. Wiss. Wien 140 (1): 620, (1931), and D. pacheri Stur , Österr. Bot. Wochenbl. 5: (49-50) 156 (1855), resemble 36. D. norica has stellate hairs with unbranched rays, 3-7 cauline leaves, and a glabrous, elliptical silicula 5-6 x 2-5-3 mm; D. pacheri has stellate hairs with branched rays, 0-4 cauline leaves and a glabrous, lanceolate silicula 6-7(-9) x 2-5-3 mm. Although these taxa are distinct in the Alps, their relationship to the arctic complex is obscure. D. norica has 2« = 64.
