378 HEPATICJE ANTARCTICA. 
subimbricatis erecto-patentibus concavis subsecundis ex 
angusta basi obovatis obtusissimis apice bilobis dentatis, 
perichetialibus majoribus nutantibus, receptaculo com- 
muni elongato obconico striato. 
Has. Lord Auckland's group. 
Stems scarcely tufted, erect, slightly incurved above, from 
one to three inches long, prolonged at the top by annual 
innovations arising from the base of the perichetium, when 
this is present. The leaves, in the series from the base to 
the summit of the stem, are constantly increasing in size. 
The receptacle is elongate, obconical of a pale tawny colour, 
striated : the barren pistilla are crowded, erect, linear, covered 
by a pair of laciniated scales, descending at a considerable 
angle from the stem and emitting rootlets. The perigonia 
are spikes situated in the course of the stems, and have 
leaves closely imbricated, erect, swollen at their bases, each 
containing several dusky oblong anthers whose pedicels are 
elongated. 
To this genus or sub-genus may be referred Junger- 
mannia Wilsoni, Tayl., (Acrobolbus Wilsoni, Gottsche) and 
Jungermannia saccata, Hooker.

Has. Campbell's Island. int 
Tufts two or three inches wide, whitish-yellow. Stems 
supine, slightly flexuose. Leaves, to the naked eye, so ap- 
proximate that the patch resembles one of Jung. furcata, L.; 
their bases are broad, the lower margin decurrent, they 7e 
so secund that under a lens the stipules are conspicuous, 
divided nearly down to the base, each segment sometimes - 
having a tooth or very short process on its outer 
towards the base.
