This differs from Hypnum cocMearifolium chiefly in the rigid dendroid habit and firmer, less inflated not 

 obtuse leaves. Eaoul's specimen (Herb. Muse. Paris, 24 b.) appears to be a state of this with more erect and less 

 concave leaves. A similar form, with branches much fasciculate, was gathered by Dr. Lyall.

 of the seta.— Plate LXXXIX, Pig. 1 : — 1, plant, natural size; 2, capsule; 3, 4, leaves; 5, apex of leaf : — all but 

 fig. 1 magnified.

 latere orti.

 compressed ; the nerve narrow, often vanishing below the cuspidate apex ; areolae narrow, subpapillose. Capsule 

 suboylindrical, large, not contracted at the mouth, often erect, sometimes almost pendulous, symmetrical. 



b. Capsula striata. Operculum longirostre.
