Hab. Straits of Magellan, on trunks of trees. Port Famine, Dr. Lyall. 

 Less than U. Hutchinsiee ; the straight cauline and large wide obtuse 



perichsetial leaves readily distinguish it from its allies. 



U. EREMiTENSis (Mitten). Monoica, caespitulosa, foliis siccitate vix 

 mutatis patentibus e basi erectiuscula suborbiculari lata concava an- 

 gustatis lineari-lanceolatis nervo sub apice evanido carinatis margine ,

Orthotrichum luteolum, Hook. fil. et Wils. Crypt. Antarct. ex parte. 



Hab. Hermite Island, Cape Horn, Dr. J. D. Hooker. 



A little larger than U. germana (Mont.), and with the bases of its 



leaves a little longer, their cells in the upper part not depressed, the 



leaves themselves not crisped when dry, and the cilia of the internal 



peristome capillary. 



U. GLABELLA. Monoica, subpulvinata, fohis siccitate appressis sub- 

 tortis madore e basi erectiuscula suborbiculari concava cellulis margi- 

 ualibus oblongis parallelogrammaticis hyalinis in seriebus pluribus 

 dispositis interioribus elongatis angustis angustatis longe lanceolatis

Orthotrichum luteolum, var.. Hook. fil. et Wils. Crypt. Antarct. 



Hab. Hermite Island, Cape Horn, Dr. J. D. Hooker. 

 The leaves not crisped in drying and the glabrous calyptra distinguish 



this from its allies. In size it agrees with U. yermana. No perfect 



peristomes have been seen. 



U. FuEGiANA {Mitten). Monoica, caule procumbente ramoso caespitu- 

 loso, foliis siccitate tortis madore e basi late obovata erectiuscula con- 

 cava margine cellulis oblongis hyahnis parallelogrammaticis in seriebus 

 pku'ibus marginata inde angustatis longe lanceolatis patentibus nervo
