This moss is equally alpine and arctic, and there is scarcely any 
other which flourishes and fructifies in such high latitudes and alti- 
tudes. It was gathered abundantly in Captain Parry’s northern voy- 
ages, and Wahlenberg remarks of it, ‘‘in alpibus omnibus altius 
ascendit prope nivem perennem, quam quis alius muscus (excepto » 
forsan Polytricho juniperino).”

of the leaves it precisely resembles Hymenost. tortile, mong with 
which it grew.
