35. D. fladnizensis Wulfen in Jacq., Mise. Austr. Bot. 1: 147 (1779)

( D. wahlenbergii Hartman ).

Often dwarf; flowering stems rarely more than 8 cm, entirely glabrous. Cauline leaves 0-2; basal leaves oblong-obovate, ciliate, otherwise glabrous, or variably but usually sparsely covered with unbranched, branched or stellate hairs. Inflorescence 2- to 12-flowered; petals 2-5-4 mm, white. Silicula elliptical, glabrous; style less than 0-5 mm. 2n = 16. Arctic and mountains o fScandinavia and o fS. & C.

This description covers a widespread arctic-alpine species- complex, which includes D. lactea Adams , Mém. Soc. Nat. Moscou 5: 104 (1817), treated in some northern Floras as specifically distinct in the following manner: Cauline leaves usually present; basal leaves with unbranched hairs only D. fladnizensis sensu stricto

Cauline leaves usually absent; basal leaves with some branched (sometimes irregularly so) hairs, occasionally with a few stellate ones D. lactea This distinction, which seems to be reasonably satisfactory in the Arctic, where both species occur, is unworkable in the Alps, where the problem is further complicated by the occurrence of D. carinthiaca var. glabrata , and putative hybrids of D. fladnizensis with this species. O. E. Schulz considered such plants responsible for the ‘erroneous’ records of D. lactea from the Alps. D. dorneri Heuffel , Österr. Bot. Zeitschr. 8: 25 (1858), endemic to the S.E. Carpathians (Mun(ii Retezatulii, Romania), differs from D. fladnizensis in its longer style (0-5 mm) and in its leaf- pubescence. The basal leaves have peculiar cilia, which are unbranched near the leaf-base and branched towards the leaf-apex; the lamina is glabrous.
