THE MOSSES OF THE AZORES. 53 
other representatives in New Zealand and in the temperate 
regions of South America. Hyophila Treleasei Card. and 
Lepidopilum fontanum Mitt. represent at the Azores two 
genera almost exclusively tropical. 
Among the mosses most worthy of notice, we shall men- 
tion in the first line some species and varieties quite endemic 
or which, at least, have not as yet been found elsewhere 
than at the Azores: Campylopus flexuosus var. fayal- 
ensis Card., C. setaceus Card., Hyophila Treleasei Card., 
Trichostomum mucronatulum Card. and T. azoricum 
Card., Glyphomitrium azoricum Card., Bryum pachy- 
loma Card., Breutelia azorica (Mitt.), Fontinalis anti- 
pyretica var. azorica Card., and Sciaromium Renauldi 
Card. Then, another series of species which are found 
also at Madeira and in the Canaries, but nowhere else: 
Ramphidium purpuratum Mitt., Campylopus azoricus 
Mitt., Bryum caespiticium var. atlanticum Card., Astrodon- 
tium canariense Schw. and A. T’releaset Card., Lepidopilum 
JSontanum Mitt., Sctaromium prolixum (Mitt.) and JS. 
spinosum (Mitt.), and Hylocomium Berthelotianum 
(Mont.). These species may be called truly Atlantic. 
Finally, we shall note still, as interesting and also Atlantic 
species: Glyphomitrium nigricans Mitt., common enough 
at the Azores, Madeira and in the Canaries, but very rare 
in Europe, where it has been recorded only from a few 
Portuguese localities; and Myurium hebridarum Sch., and 
Hypnum canariense (Mitt.), both of which exist in the 
three clusters of islands, and of which the first is also found 
in the Hebrides and the second in Ireland.
