Conklin—Preliminary Report on a Collection of Hepaticae. 1001 
appressed to the stem. The subulate underleaves however on the 
horizontal parts of the stem, distinguishes the plant from the 
Cephalozia , hut these portions of the stem are often rotted 
away. The perianth of Cephalozia Francisci as well as its 
habitat on the ground distinguishes the species from Harpan- 
ihus scutatus which so far as observed grows on old wood. 
Geocalyx graveolens grows on old rotten wood preferably 
buried. At Lutsen the yellowish green color of the colonies 
distinguished the species at a glance from the vivid bright green 
of its common associate, Lophogiu incisa.
