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-

 ascendit prope nivera perennem, quam quis alius muscus (excepto 

 forsan Polytricho juniperino) ."

This seems to be the var. I. amblyodon of the ' Br. Europ.' ; W. am-

 of the leaves it precisely resembles Hymenost. tortile, along with 

 which it grew.
