NO. 3 BRITISH EAST AFRICAN MOSSES — DIXON 1 3 



vagiiuila and seta being extremely long, together about equalling 



the capsule length, it is much less immersed, often not even hidden. 



The differences from N. macrocarpa Broth, may be tabulated thus : 



Seta Tlieca Tet-th Processes 



N. macrocarpa i mm. 3-5 mm. striolate at base equalling teeth 



N. submacrocarpa 2-2.5 mm. 2-3 mm. papillose to base half length of teeth 



Brotherus gives for his species certain characters derived from form 

 of leaf, and branching, which do not quite agree with the present 

 plant. I am not inclined, however, to lay much stress on these differ- 

 ences, as the branching and form of leaf apex appear to vary con- 

 siderably within the limits of the same species in this group ; they 

 certainly do in N. platyantha. In fact the whole group of African 

 species, A''. Hoehncliana, N. V alcntiniana, and the above mentioned 

 plants, are in my opinion quite inseparable from one another by 

 vegetative characters alone. For this reason I feel some doubt as 

 to the validity of A'^. subplatyantha Broth. ,^ which appears to be 

 separated from N . platyantha on vegetative characters alone. I 

 have not, however, seen the plant itself.
