376 HEPATIC® ANTARCTICA. 
fidis integerrimis, calyce terminali oblongo compresso 
truncato ore integerrimo. 
Has. Lord Auckland's group. 
Tufts several inches wide, pale yellowish-olive. Stems 
scarcely one inch long, variously branched, ascending at their 
summits. Leaves nearly kidney-shaped, their margins 
slightly incurved, hence they are concave. Stipules rather 
small in proportion to the leaves, bifid at the top, with a 
very shallow notch, the segments subacute. "The leaves on 
fertile shoots in a series rapidly increasing to the pair form- 
ing the perichetium, which are the largest and most erecf, 
while the third or stipular piece is very small. Calyx ter- 
minating the shoot of the preceding year, from a narrow base 
oblong truncate and compressed before the issuing of the 
capsule, afterwards resembling a flattened cylinder slightly 
curved towards the upper side of the stem. 
'The Jungermannie with round concave imbricated leaves 
and bifid stipules, growing in the North of Europe, bero 
calyces subcylindrical or ovate; the present is excentric : 
having that organ compressed and truncate. So it may Ww 
the type of a new genus as valid as many proposed in mo- 
dern times; and to which, perhaps, our J. strongylophylla 1s 
likewise to be referred.

Has. Lord Auckland's group. 
Tufts of parallel, erect, simple, pale straw-coloured shoots, — 
a little thickened and incurved at their summits. The sean? | 
from their incurved margins and inflated condition represent 
sacks partly divided. The stipules, likewise, which are much 
wider than the stems and about one fourth of the size of the 
leaves, are very hollow and mostly entire. The leaves pre 
shaped somewhat like the human external ear, and gate: 
current in front. Old plants turn of a dusky-purple colour. -
