This species has been found in N. Icel. only, in the parts around Eyjafjörður and
in the Skagafjörður valley, especially in the vicinity of Mælifell, see fig. 43.
It may here be mentioned that the name Triticum biflorum Brignoli is not to be
used for the Icelandic plant. T. biflorum is an alpine species occurring in a restricted
area in Austria (Vorarlberg and Tyrol), and in Switzerland (Wallis).

Gliemann, 1824, p. 137,—Vahl, 1840, p. 375.—Babington, 1871, p. 342.
If by this species, recorded by Gliemann, 1824, and marked by Vahl as a native,
ís meant A. alpina Scop., there has most likely been a mistake; it is not probable
t at this continental species should be found in Iceland.
Specimens from northeast Greenland seem to belong to A. latiglume.
