REPORT ON THE MOSSES 
Hab. Growing horizontally on a tree trunk near the ground, hill 
south of the Rebang, alt. 2,800ft., Abor District, 8th January 1912 ; 
leg. urkill (n. 37787). 
A well marked species of this interesting and very beautiful genus, 
having for its nearest ally C. parvifolium Bry. jav., but distinct from 
that and all the Xndo-Malayan species in the amphigastria, which are 
perfectly orbicular, with a shorter, cuspidate point. The comparatively 
broadly margined leaves, and the fine and almost even denticulatien 
over the whole of the upper half both of leaves and amphigastria are 
also good characters. The fruit is known in but few of these species, 
so far as I am aware in only C . Adiantum and C. Ilookerianum , and 
these have the peristome much less developed, indeed comparatively 
rudimentary. X have figured part of a peristome on Plate XI, fig. 9.
