382 HEPATICÆ ANTARCTICA. 
Has. Lord Auckland's group. 
Growing rather scattered, than in patches, on the surface 
of other Hepatice, whitish-green. Stems about half an inch 
long, creeping, their tops acuminate and recurved, appearing 
channelled on the upper side from the closely imbricated 
leaves approaching at their bases. Leaves with large cellules, 
nearly transparent when viewed under a lens in water; they 
are widest at their insertion, their inferior margin is very 
decurrent, their sinus is obtuse, the segments much acumi- 
nate and divergent. Stipules remarkable for their size, 
from a round and concave base dividing usually into six 
segments, which embrace the leaves and give to the shoot a 
very spinous appearance. The anthers are situated at the 
bases of the perigonial leaves on the upper part of the stem 
in the channel between the leaves alternately; they are 
white, rather large, and are pedicellated. 
30. J. allodonta, n. sp.; caule prostrato implexo ramoso, 
foliis distichis imbricatis patentibus ovato-oblongis obtusis 
subbidentatis, stipulis minutis lanceolatis bipartitis inte- 
gerrimis. 
Has. Lord Auckland's group. 
Patches some inches in diameter, lurid-green. Stems about 
one inch long, irregularly branched. Leaves lying in one 
plane, oblong, with a wide base, rather rounded at their tops; 
having commonly two teeth and an irregular sinus be- 
tween them; often, however, there is but a single tooth 
and sometimes none; when one tooth is wanting it is always 
the posterior. Stipules deeply cloven, the segments linear 
acute, entire. 
The shape of the stipules, the lurid colour, and the more 
oblong leaves will distinguish this plant from Jung. Tricho- 
manes, Dicks. in a barren state. :
