The ON:act position of tbis species is not very clear ; tbe narrow incra^^satc 

 cells suggest tlie Alpiniformta SectioUj but tlie leaf fornij stoutly excurrent 

 nerve^ and capsule bardlj agree there. The form of the capsule, and the 

 broad, almost connate peristome teeth, very densely lamellate, and very 

 highly and strongly papillo.se on tlic dorsal surface, are rather marked 

 characters, as is also the unusual basal, annular membrane from wldch the 

 outer teeth spring, somewhat resembling that of the Ilccmatostoma Section, 

 but much higher, and reaching wel) above the orifice of the capsule. 



Of this genus, the largest among mosses, the only otlier species that I have 

 seen recorded from New Guinea is the almost cosmopolitan 7>. coronalum^
