The species in the above group of mosses are difficult to determine. Some 

 were formerly united under the name of U. Aduncum, and probably may yet 

 be ascertained to be only varieties. Between H. Fluitans and H. Lycopodoides 

 there is indeed a wide difference, but some of the intermediate forms appear to 

 pass into one another. Perhaps the next few years will give us an entire re- 

 arrangement of the whole order of mosses. 



2. Leaves serrulate, nerved more than half-way. 



Fig. 9. Hypnum uncinatum. 

 Sickle-leaved Feath&r Moss (a) .
