Not found below the height of 500 m. on the west side of the Cameroons Mountains. In 

 ti i p neighbourhood of Bomana, (570 m. above the sea, I very often saw this möss, quite eovering 

 the tree-branches in very dense ttifts. On the west side of the Little Cameroons' Pike I found 

 it at a height of 800 m., growing comparatively thinly at the ends of the branches of trees.
