species. 
Type European. It has been reported from es igor

British Columbia; also in Texas and New Mexico, collected by 
Wright.

Differs from the first two species by having no cilia, and the 
capsules are only faintly striate above and below when old.

We have specimens collected by Bolander, which have been sub- 
mitted to Venturi and referred to this species with some doubt 
from the description in Braithwaite’s British Mosses.

Sullivant says that this is a very distinct species related to O. 
“™pesire and O. Sturmii, but differing in the markings of the 
teeth, the longer, cylindric capsule and the bistromatic cells of the 
leaves. In February, 1890, Dr. Watson sent me a portion of this 
type. It is remarkable for its dense black stems and closely ap- 
Pressed and crowded leaves. We also have specimens from the 
Department of Agriculture, received November, 1890, from Bo- 
lander’s duplicates, which agree with the types of this species. 
The figures in Sullivant’s Icones represent the capsules longer 
and more cylindric than the types. The capsules are not more 
than a third longer than broad, 1.5 by I mm., and less exserted 
than figured, and the teeth are more papillose than the cilia “ 
‘More trabeculate joints.
