HEPATICIE ANTARCTICA. 393 
planis, calyce laterali compresso late ovato, ore bilobo, 
lobis denticulatis, capsula basin usque quadripartita. 
Has. Lord Auckland's group. 
Tufts loose, of a pale yellowish-green. Stems from three 
to four inches high, branching usually in a dichotomous 
manner; branches rather short, patent. Leaves closely im- 
bricated, and even when moistened recurved, so as to give to 
the upper side of the stem a very convex appearance; their 
margins are quite entire, except of the perichetial pair, in 
Which they are dentate. Before protrusion of the capsule, 
the calyces have their mouths compressed, their upper sur- 
convex, while beneath there is a longitudinal prominent 
ridge, The capsule is divided into four valves down to the 
very base. 
From the European Jungermannia platyphylla, L., the pre- 
Sent is, at first sight, distinguishable by its ramification, 
Which is not so decidedly pinnate, by its more distant 
branches, by the lower lobes of the leaves being more acute 
as well as by its being toothed exteriorly towards the base, 
by the plane margins of the stipules, and by the complete 
division of the capsule into valves. !
