HEPATICJE ANTARCTICA. 367 
von Esenbeck, Lehmann, Lindenberg, Gottsche, Raddi and 
others have lately endeavoured to establish new: genera. 
These, we consider for the present as not entirely accepted. 
by Botanists, but in the light of proposals, deserving their 
best consideration. We have, therefore, in the following 
arrangement steered a middle course, and separated the 
Jungermannie into sections to which we have given the 
names of the genera lately advanced, so far as they apply to 
the species from Campbell’s Island and Lord Auckland's.

Plants growing in somewhat. a tufted manner, up through 
Musci and. other Jungermannie ; blackish-purple above, the 
More concealed parts of a dusky olive colour. Stems 2 or 
3 lines long, much and irregularly branched. Leaves very 
minute, alternate, scarcely imbricated, oval or obovate, 
Sometimes entire. and very obtuse, more commonly and 
especially on the older stems with a shallow rather obtuse

Scatiose. The perichetia are subrotund and have closely
