MOSSES FROM THE WESTERN GHATS 161 
Pterobryopsis ; Capsule with stomata; peristome inserted far 
ing irregular 
thickenings, smooth, not papillose. Ring broad; preperistome 
wanting. é 
alyptotheciwm : Capsule without stomata ; peristome inserted 
near the orifice; dorsal surface of teeth normally developed ; pre- 
peristome present. Ring wanting. 
the 
characters of each of these; thus the capsule is without stomata, 
but there is no preperistome, the teeth are inserted at some dis- 
tance below the orifice, and there is a narrow longitudinal waved 
or zigzag ridge of irregular thickening along the dorsal surface of 
the outer teeth. 
In considering the true position of the plant we were driven to 
the conclusion that these genera, as treated by B 
ee 
ara which it is reason- 
able to look upon as of systematic importance, there is little to 
dium), are by no means normally developed, being very irregular, 
with numerous thickenings on their dorsal surface very similar to

stome of the genus as “ sehr rudimentir.”’
