302 BRYOLOGY OF NEW ZEALAND. 
Zealand specimens I am fully persuaded both that the Australasian 
and American plants are in n y separable from the African 
species, and that the varieties rest on too slight characters to be 
worth maintaining. I have also examined original seat of the 
other three species of R. Brown’s given in the sy onymy, and of 
A. arctoaeoides C.M. & Beck. (re-deseribed by C. Mueller j in Hedwig. 
xxxvii, 83) and they are all simply referable to the same species, 
as is without doubt, from the descriptions and from Roth’s figures,

a Blindia or a Dicranum or Dieranella, from the usually shit? faleate, 
oten blackish leaves. The leaves may be erect or nearly so, or 
strongly faleate, almost circinate; most commonly the subule is more 
or less faleat e from an erect. base. The structure of the leaves is
