Icelandic: Burstajafni. Danish: Almindelig Ulvefod. English: Common Club-moss.
Although it is recorded by König & Miiller, loc. cit., and entered in all the
older lists, it was first found with certainty in 1917 at Snæhvammur on Ormastaða-
fjall in Breiðdalur, E. Iceland (D. 7). Specimen in H.H.
The specimens found are sterile, with very slender stems, 8—9 cm high, and
a good deal branched. The leaves are short, not exceeding 4 mm.—Most likely the
older records may be referred to L. annotinum.

Lycopodium complanatum Linn.
This species is for the first time entered in Gliemann’s list (1824, p. 182).
Hjaltalín and Vahl also record it, but evidently there is a mistake; the species in
question is most likely L. alpinum.
