The size of the cäpsule appears to be very variable. On the application of water the 

 extern peristomial teeth break off at the base. Rudimentary cilia may, perhaps, be found, hut 

 the insufficient material has not permitted me to decide this point. 



This species is one of the most comraon mosses in the Oameroon-territory on the west side 

 of the Cameroons Monntain from the sea up to a height of 1,200 m. and may be still higher. 

 It is abundant especially in the deep excavated river-beds, where it grows in large masses at the 

 ends of the branches of the trees. On the south-east side of the mountain, I found it very small 

 and gracile on basaltic rocks in the neighbourhood of Bea, 950 m. över the sea. Mostly barren.
