numerous problems as to the identity or otherwise of certain of the South 
African species with allied species from the North Temperate regions. I 
am not inclined to think that this identity is likely to be found in very 
many species ; at the same time I am convinced that it exists between a 
certain number of plants where it has not hitherto been recognised, and 
some of Mr. Sim's gatherings from high mountain elevations have gone 
a good way to confirm this. I am quite convinced for example that Bryum 
afro-alpinum E,ehm. (and probably B. Wilmsii C. M. also) is identical with 
B. alpinum Huds. ; while several gatherings of another species are to me 
entirely indistinguishable from B. MuehlenhecJcii Bry. Eur. ; Polytrichum 
flexicaule C. M. is quite inseparable from P. commu7ie L., while more than 
one of the forms of Tortula described by C. Mueller from South Africa are 
I think entirely identical with T. ruralis (L.) {Barhula afro-ruralis C. M. ; 
B leucostega C. M.). One or two other identifications with European species 
will be found in the following list. 
The types, unless otherwise stated, are in my Herbarium. 
The figures are drawn from the type-specimens unless otherwise 
described. 
In order to economise space and to prevent repetition I have employed 
the following abbreviations :

multiporosa."
