Cephalozia curvifvlia Dumort. , (Fig. 3.) can usually be distinguished 
without a lens for the leaves seem to surround the stem rather than to grow 
out horizoatally. The plants are generally found on decaying logs in 
swamps, and have a greenish to a reddish or brownish color. The leaves 
are concave, the lower portion folding back upon the upper, seeming to form 
a kind of sac. The leaves are cleft to the middle or below the lobes, ending 
in long slender incurved points or hooks. The cells are small and quadrate 
in shape. 
Of the species having decur 7 'ent leaves, Cephalozia connivens (Dicks.) 
Lindb., (Fig. 4,) shows the least tendency in that direction. These plants 
may be found in wet swampy land, and can be readily identified by the large 
size of the leaf cells. The leaves are much more rounded in shape than 
those of the other species. They are not deeply cleft, the more or less con- 
nivent lobes being bordered by a row of cells of uniform size and shape.
