renchymaticarum prosenchymaticarumque marginata interioribus an-

pressis latitudine 5,55 longitudine у оу uncie metientibus levibus, 
perichztialibus exsertis late-lanceolatis erectis obtusis laxe convolutis

ciliis angustis 8 brevioribus ?, calyptra nuda fusca. 
Hab. Straits of Magellan, on trunks of trees, Port Famine, Dr. Lyall. 
Less than U. Hutchinsie; the straight cauline and large wide obtuse 
perichzetial leaves readily distinguish it from its allies. 
U. EREMITENSIS (Mitten). Monoica, czspitulosa, foliis siccitate vix 
mutatis patentibus e basi erectiuscula suborbiculari lata concava an- 
gustatis lineari-lanceolatis nervo sub apice evanido carinatis margine 
ad apicem baseos dilatato et inde recurvo minute crenulato cellulis ad 
baseos latera seriebus pluribus parallelogrammaticis hyalinis interiori- 
bus angustis cito in rotundatas diametro y uncis metientes trans- 
euntibus papillosis, perichetialibus lanceolatis, theca in pedunculo 
triplo longiore ovali plicata basin versus levi, peristomio dentibus 
8 bigeminatis apicibus liberis ciliis 8 angustis capillaribus subæqui- 
longis, calyptra glabra. 
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, foliis siccitate appressis sub- 
tortis madore e basi erectiuscula suborbiculari concava cellulis margi- 
nalibus oblongis parallelogrammaticis hyalinis in seriebus pluribus 
dispositis interioribus elongatis angustis angustatis longe lanceolatis 
patentibus nervo sub apice evanido carinatis margine minute crenulato 
cellulis remotiusculis rotundatis diametro 5,455 uncie metientibus pa- 
pillosis, perichztialibus paululum latioribus, theca in pedunculo eam 
duplo superante ovali plicata, collo brevi, calyptra nuda apice rugosa. 
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. germana. No perfect 
peristomes have been seen. 
U. FuEGIANA (Mitten). Monoiea, caule procumbente ramoso cespitu- 
loso, foliis siccitate tortis madore e basi late obovata erectiuscula con- 
cava margine cellulis oblongis hyalinis parallelogrammaticis in seriebus 
pluribus marginata inde angustatis longe lanceolatis patentibus nervo
