Moist dripping rocks, not uncommon. Fr. Autumn. — I am happy 

 to learn that Mr. Wilson, who has gathered this and the preceding 

 Gymnostomum in Wales, considers them to be truly distinct. The pre- 

 sent is, however, by far the most common. 



** Stems short, scarcely branched. 



6. G. ovdtum, Hedw. (hairy -leaved Beardless-Moss); leaves 

 ovate erect concave piliferous, nerve expanded into a gem- 

 miferous membrane, lid rostrate. Muse, Brit. ed. 2. p. 21. t. 7.

 v. 2. n. 8. — (3. gracile; capsule oblong. 



Banks and walls. Fr. Feb. — This species varies considerably in the 

 length of its capsules, hence I have constituted 2 vars. In all states, the 

 nerve is expanded into a membrane on each side from above the middle 

 to the apex of the leaf: but Mr. Wilson observes that gemmse are not 

 always attached to it. 



7. G. truncdtidum, HofFm. (little blunt-fruited Beardless- 

 Moss) ; leaves oblongo-obovate acute apiculate patent reti- 

 culated pellucid entire nearly plane their margins recurved, 

 capsule ovate or turbinate, lid obliquely rostrate. Muse. Brit.

On banks, walls, and fallow-fields. Fr. Winter. — Mr. Lyell and Dr. 

 Greville find this occasionally with the stem branched in a fasciculated 

 manner, with 6 — 8 branches, each branch bearing a capsule. 



8. G. Wilsoni, Hook. ( Wilsonian Beardless-Moss); leaves 

 oblongo-obovate obtuse apiculate minutely reticulated opaque 

 entire, the margin slightly recurved, capsule oblongo-elliptical 

 a little contracted at the mouth, lid obliquely rostrate, calyptra 

 scabrous above. Hook. Bot. Misc. v. I. p. 143. t. i\. — G. af-
