NO. 3 BRITISH EAST AFRICAN MOSSES — DIXON I9 



to those of some species of Rhabdozveisia, and on this account it 

 might be placed in the Dicranaceae. On the whole, however, it 

 seems to be best placed in the Pottiaceae, near Astomitm and the 

 subgenus Kleiowcisia of Hymenostomum. 



The plant is paroicous ; but I suspect it may be heteroicous, as I 

 have seen what seems to be a male flower below the fertile flower. 



The capsule is, accurately speaking, neither cleistocarpous nor 

 stegocarpous. The lid is perfectly differentiated, and there is a 

 distinct row of subannular cells at the orifice ; these may be in more 

 than one series. On the other hand, the lid is probably not normally 

 functional ; the capsule wall is of extremely delicate texture and under 

 pressure breaks up without the lid being detached, and this appears 

 to be the case also under normal conditions. 



It is unfortunate that the altitude is not recorded. The association 

 of the plant with Caiiipylopodiuin would seem to indicate a compara- 

 tively low level.
