from recent investigations it becomes evident that they are only aquatic 
forms of C. Americanum and should have been given the name that they 
were distributed under by Austin in his Musci Appalachiani No. 289, C. 
Americanum var. fiuitans (p. 49. 1876). 
Pleuroziopsis Kindb. Check List Eu. & N. A. Moss. 19 1894. 
Girgensohnia Kindb. Sp. Eu. & N. A. Bryin. 1:43.1896. 
Climacmm Sect. Girgensohnia Lindb. Act. Soc. Fenn. 10:248.1872. 
This is another instance of the replacing of a generic by a subgeneric 
name. P. ruthenicwn (Weinm.) Kindb. is our West Coast species found also 
in Asia and Japan. 
Cryphzea Ravenellii Aust. has been referred by Kindberg (Br. Eu. & N. 
A. 1:7. 1897) to Forsstroemia and Brotherus has accepted this opinion. I 
have already stated (Bull. T. B. C. 3 2:263.1905) that Austin was quite right 
in placing it in Cryphcea. 
Dendropogonella E. G. Britton, new name. 
Dendropogon Sch. Bot. Zeit. 1:377.1843. not Raf. Neogenyt. 3:1825. 
As Rafinesque’s genus has been taken up recently by Dr. Small for 
Tillandsia usneoides L. (Flora S. E. United States 244.1903.) Schimper’s 
name succumbs to the fate which seems to await a homonymn, hence 
I have added a syllable in order to distinguish the genus of the true mosses 
from our common “ Florida Moss.” Only one species is known from Mexico 
and the Island of St. Thomas, Dendropogonella rufescens (Sch.) E. G. B.
