HEPATICH ANTARCTICA. 289 
emarginate, slightly incurved at the top; the cellules are in 
distinct dots, and so much larger towards the inferior margin 
as to give the appearance of the presence of a pellucid nerve 
as happens in M. inequilaterum, Nees. Stipules scarcely as 
wide as the stems ; they have three acuminate teeth, issuing 
from a shallow common portion. The diminutive size, irre- 
gular branching, great disproportion between the breadth of 
the stems and of the leaves, their rather distant position and 
unequal cellules, give characters, when taken together, that 
readily distinguish the present from all its congeners. 
48. J. nutans, n. sp.; caule laxe cespitoso erecto incurvo 
simplici, foliis arcte imbricatis patentibus concavis latissime 
ovatis apice inzqualiter bifidis, margine subintegris, sti- 
pulis erectis oblongo-rotundatis concavis apice subdentatis, 
stolonibus subbasilaribus adscendentibus apice demum fo- 
liosis. à

Stems tufted, simple, nodding, or bending down, as in 
Jungermannia tenax, Grev.; almost white near the root, pale 
dusky-green above, except at the summit which is often 
blackened. The leaves are almost eup-shaped, bifid, the 
inferior segment the smaller, the cells project at the margins 
Which here and there especially towards the top have one or 
two teeth : the cells are large at the centre, and at the bases 
of the leaves. - 
In Jungermannia tenaz, Grev., which exhibits in some 
degree the habit of the present, the stems are branched, and 
the leaves multifid.
