Dioicous ; laxly pulvinate and vaguely caespitose, olive-green and 

 hoary above, soft. Stems i — i in. high, erect or procumbent, rooting at 

 base, repeatedly dichotomous. L. densely crowded, erect and incum- 

 bent when dry, patulous when moist and bending upwards from the 

 middle, from a longish ovate base, lanceolate, gradually narrowed 

 into a longer or shorter rough hair, concave below, carinate at apex, 

 the margin plane or slightly recurved at the middle, nerve strong, 

 channelled, very prominent above and with two ridges at back ; cells 

 above small, roundish-quadrate, obscure, in 2 strata, at base elongate 

 and somewhat sinuose, i — 3 rows at margin short and hyaline. Caps, 

 on a short yellow subarcuate seta, very small, oval, leptodermous, 

 smooth, brownish-yellow, rugulose when dry, annulus very narow of 

 2 — 3 rows of cells; lid yellow-red with a short beak, teeth red, 

 lanceolate, nearly entire ; calyptra 4-lobed. 



Hab. — Granite and sandstone rocks in mountains. Fr, 5 — 7.

This moss is very close to G. trichophylla, but that species is more 

 robust, the nerve thinner and less prominent at back, with a nearly smootli 

 hair, the cells internally scarce nodulose, the seta longer, capsule twice 

 larger, oblong, subopaque, plicate, firmer, lid rostrate ; from G. pulvinata it is 

 still more distinct by its dioicous infl., lax olivaceous tufts, taper-pointed 

 leaves and firmer subsinuose areolation. It will probably be detected in 

 many more localities.
