Caulis i-2-uncialis. Folia viridia, straminea, aurea, fuscescentia vel in- 
terdum nigro-fusca, pilo plus minus elongato, forsan in terris calidioribus 
longiore. 
Very variable in external appearance, in the colour of the leaves, 
and the length and curvature of their white points. The species 
appears to abound throughout the southern hemisphere, in Europe 
extendiug as far north as the south coast of Britain, and in America 
to Alabama. 
Besides the synonyms quoted above, to which it is probable 
some others will have to be added, specimens are found in her- 
baria as Campylopus canescens, Schimp., from the Falkland Islands, 
Lechler, n. 90, and C. capensis, Schimp,, from South Africa, Breutel.
