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

 Very near to U.fulvella in habit, size, and in the torsion of its leaves ; 



but the base of its leaves with many series of pellucid marginal cells, 



the margin towards the apex irregularly erose, and the calyptra with few 



appressed hairs.

Hab. Terra del Fuego, Mr. Darwin. 



Resembles very closely U. Puegiana, but with larger leaves, which 



have their cells more closely placed, and the vaginula pilose.

Hab. Tasmania, on trees, rivulet behind Cumming's Head, Western 

 Mountains, Mr. Archer; Mount Wellington, and in New Zealand, 

 Wairoa River, Kaipara, Mossman. 

 Corresponding in size with U. crispa, but with leaves of a different 



form at the base, erose margins, and cells in the upper portion larger 



and further apart ; the capsule is also thinner.
