This species is frequent in Vestfirðir, as also in eastern Iceland. In S. it is found
in two localities: Hraungerði in Flói (S.S., 1931, p. 40), and Oddi (H.J., 1901),
while it seems to be absent in the other parts. It is not recorded from the central
highland. See fig. 71.
I found it myself in two places in E. : at Hallormsstaður, and some way south
of Valþjófsstaðir in Jökulsárdalur (1935); in both localities some few specimens
only were seen.
Life-form: G. (Rhizome Geophyte).
In swampy places, in meadows.
Flor. VI—VII; fr. mat. VII—VIII.
Max. height: 30 cm; average: 19 cm.
