Notes: Elven and Grundt: Draba incana occurs in two indistinctly different morphs in Fennoscandia, one lowland and coastal (D. incana as to type) and one upland and northern (unnamed). The type morph is a nearly obligate biennial with unbranched or little branched rhizome, very many small stem leaves, and a compact infrutescence that elongates only moderately. The inland morph is mostly a perennial (even if flowering shoots die) with branched rhizome with many side rosettes, stems often branching, stem leaves fewer and larger, and an infrutescence that mostly elongates strongly. The inland morph occurs both in Fennoscandia, reaching the Arctic in Norway and Russia, and in Iceland north to the Arctic. The type morph reaches the Arctic in Norway, Iceland, Greenland, and northeastern Canada. Intermediates between the morphs are very common in Fennoscandia and perhaps in Iceland. The variation is not sufficiently analysed for a formal treatment and no names are available.
