Cephalozia bicuspidata is one of the rare species in the Dis¬ 
trict. 
C. lunulaefolia is very common on logs, and rotten wood in 
swamps and dense woods. 
Cephalozia curvifolia is very common on logs in the forest, 
preferring bark denuded logs and before the growth of mosses 
have invaded the host. Large logs have been observed covered 
with the species, green, brown or reddish in color depending 
upon the amount of exposure to the sun. 
Cephalozia pleniceps grows on cut peat on buried stump roots 
along old paths through cedar swamps. Cephalozia connivens 
in wet springy places on old wood. 
Cephalozia Macounii and Cephalozia serriflora collected only 
once, and growing together, were found thickly covering an old 
log in one of the most inaccessible places of the Black River 
gorge at Manitou Falls. Rarest of our tiny plants, they could 
not have chosen a place of greater security.

Many forms of the composite Cephaloziella divaricata (Smith) 
Dumort. occur in this District. The two species above only 
have been determined from material sent Prof. Douin. TT ntil 
his mougraph of the genus is available for study the bulk of 
material remains undetermined.
