This species was first recorded for Iceland by Drejer, loc. cit. (after specimens
in Hornemann’s herbarium) ; it is also cntered in Babington’s list from 1871, and
Gronlund, 1881, has admitted it on Mörch’s authority. As no specimens were actually
in evidence, Stefánsson omitted it in his Flóra Islands.
A closer investigation in 1935 of the herbarium matcrial kept in H.H., however,
brought to light several specimens of this plant, determined as C. rariflora and
C. limosa ; thc oldest of these specimens was found by Ól. Daviðsson in Hraundalur
in Fljót, N., in the year 1902. The close rescmblance to the two aforementioned
specics may account for the error of detcrmination.

North Amcrican Flora, vol. 18, part. 6, 1935, p. 351.
