Droseraceae.
Drosera anglica Huds.
Drosera longifolia, K. & M., 1770, p. 206.—Babington, 1871, p. 296.
This species was recorded by K. & M., loc. cit., and is also entered in Babington’s
list, loc. cit. It is, however, rather unlikely that it should have been found in Ice-
land ; no specimens are known, and it might be safer to exclude it from the flora
of Iceland.
