othecii species?). Mixed with Hypnum Sprucei in Drummond’s 
Musci of British and Arctic, America. The specimen communi- 
cated. by Mr. Sullivant in 1sfo, 
In habit this moss resembles Plagiothecium Passaicense, Aust., 
but is much larger (a little larger than Pl. pulchellum, Dicks.). It 
also resembles Hypnum cylindricarpum in size and in the reddish 
color of the stems, which shows through the leaves under the lens, 
It is remarkable for its narrow straight leaves distinctly recurved 
on the entire margins, with the cells at the base not widened and 
scarcely any of them shortened, while those from far above the mid- 
dle towards the apex become gradually much shortened. The 
female flowers are numerous and scattered from the base to above 
the middle of the stem. Male fis. and fruit not seen.
