396 HEPATICA ANTARCTICA. 
Tufts several inches wide, black, the shoots shining, at the 
very summits sometimes purplish; branches for the most 
part solitary, by no means pinnate, of nearly equal thickness 
throughout. The inflated auricle has its lower end below the 
inferior margin of the leaf. Stipules bipartite, having so 
large a tooth exteriorly on each segment, that the entire may 
almost with propriety be said to be quadrifid. What is rare 
in this genus; the plants are usually monoicous, or have 
perigonia and perichetia on the same stems ; the former rest 
on short stalks, and are renato-rotundate, having in the dry 
state a longitudinal groove observable on the upper side, 
where the inner margins of the inflated closely imbricated 
leaves meet; the perichetia have their three leaves so secund 
and so voncave, as to appear as rounded bodies. This species 
possesses some points of affinity with Jungermannia fr agili- 
folia, Tayl., lately observed in Ireland and in Switzerland, a 
plant equally minute, but scarcely so uniformly black and 
shining, and which has the leaves less densely cellular, while 
the perichetial are dentate. da Te

Has. Lord Auckland’s group. 
Patches several inches wide, reddish-brown. Stems nearly 
two inches long, irregularly yet somewhat pinnatedly branch- 
ed ; branches erecto-patent, curving upwards. Leaves COP- — 
cave, usually apiculate; the auricle reaches below the lower | 
margin of the leaves, and is removed from contact with "ei 
stem. Stipules quite entire, with acutely bifid tops 5 they are 
scarcely wider than the stems. The barren perichetia “aX 
a rounded summit, which probably is altered in the calyce" 
ferous plant; the leaves are all erect, acuminate, and e ey 
the two lateral are oblong, each with an inner lobe whos? 
margin is reflexed, the third or stipular leaf is divided deeply 
into two lanceolate, apiculate, entire segments. ae 
The present is nearly allied to Jungermannia alr
