952 Draba oblongata R. Br.
This arctic species has a circumpolar distribution (Hultén, Circumpol. Il, p. 12, 312 and map 4). It belongs to the D. alpina group (cf. Fl. Eur. 1/1964, p. 310). The map includes D. micropetala Hook., which may be identical ( or almost so) with D. oblongata (cf. Hultén, I. cit. and Fl. Eur., I. cit.).
