Icelandic: Haugarfi, Taðarfi. Danish: Almindelig Fuglegræs. English : Chickweed.
Common throughout Iceland, except in the central parts, from which it has not
yet been recorded.
It is especially bound to the cultivated areas and to the neighbourhood of in-
habited places, gardens, etc. At the farm Bessastaðir, S.W., I observed it in 1934.
It was a very noxious weed everywhere in the fields, occurring there in great
abundance.
f. gymnocalyx Trautv., with glabrous sepals, is frequent.
Life-form: Th.
In cultivated soil, gardens, below sea-fowl cliffs, in waste piaces, near hot springs, etc.
Flor. V—IX; fr. mat. VI—IX.
Max. length of shoots: 60 cm; average: 10 cm.
Geogr. area: Am.: Throughout N. Am.—S. Am.: Patagonia and antarctic islands,—
Greenl.: (introduced?) W. 60°—62°; 67°. E. 60°—61°32\—Eur.: Fær.; E.S.I.;

Stellaria uliginosa Murr.
Babington, 1871, p. 299.—Bisiker, 1902, p. 227.
Babington, loc. cit., records it as a common plant on the authority of Mörch,
and gives two localities: Staðarfell and Reykholtsdalur, after Steenstrup. Bisiker
records it from Seyðisfjörður. There are, however, no specimens in evidence, and
it might be safer to exclude it from the Icelandic Flora.
