In the absence of peristome, allied to the East Indian B. 
rufescens; but the present is a rather larger species, with more 
subulate leaves, not so straight, and stiffly appressed when dry ; 
they are also more contracted at the base.

The specimens are too old and too young to show the peristome, 
but they appear to belong to this species.
