EvANS: REPORT ON THE HEPATICAE OF ALASKA 601 
semblance to those of Riccardia. In L. setacea, reported from 
Alaska and probably occurring in British Columbia, the plants 
are much smaller, while the deeply quadrifid, crowded, concave 
leaves with slender divisions are relatively much larger. Among 
European species L. Pearsoni Spruce,* of the British Isles and 
Norway, comes somewhat nearer to L. sandvicensis on account of 
its lax habit and distant leaves and underleaves. But in this 
species the leaves and underleaves are considerably larger than in 
L. sandvicensis, the leaves are occasionally five- or six-lobed, the 
androecia are usually terminal on long lateral branches and the 
antheridia occur singly. Since L. Pearsoni has been found in com- 
pany with Anastrepta orcadensis there is a possibility that it may 
yet be discovered in Alaska. At the present time the perianths 
are unknown, although the female inflorescence has been described.
