HEPATICZ ANTARCTICA. 473 
42. J. subviridis, n. sp.; caule cæspitoso prostrato ramoso, 
foliis laxis secundis erecto-patentibus obovatis emarginato- 
bifidis segmentis obtusiusculis, margine anteriori gibboso, 
stipulis ovatis bifidis utrinque unidentatis. 
Has. Cape Horn. ; 
Tufts two or more inches wide, very pale green when 
moistened. Stems scarcely half an inch long, decumbent, 
their tops ascending. Leaves scarcely touching one another, 
the anterior margin having the greater curvature, they ap- 
pear bulging upwards; substance dense. 
is species closely approximates to the L. discedens, 
Nees, but the leaves are shorter, wider, with a deeper sinus 
and more acute segments, and the stipules are not so 
slender, 
(Chiloscyphus, Nees v. Esenbeck). 
43. J. pallido-virens, n. sp.; caule implexo procumbente 
subramoso, folis subimbricatis patentibus oblongis apice 
subemarginatis ceterum integerrimis, margine anteriore re- 
curvo, stipulis minutis oblongis bifidis, segmentis subulatis 
extus unidentatis, calyce in ramo brevi terminali oblongo 
trigono subcompresso apice laciniato-ciliato. 
Has. Cape Horn. 
Patches wide, pale yellowish-green, by exposure turning 
dark brown. Stems two inches long, sparingly divided; 
shoots nearly one tenth of an inch wide. Leaves minutely 
cellular, loosely imbricated, erecto-patent, their tops either 
rounded or truncate, having a single obscure tooth or, what 
is more common, a shallow emargination; the leaves are 
connected by the intervention of the stipule. This is minute, 
not above half as wide as the stem, concave, oblong, with 
Setaceous segments, each bearing exteriorly a shorter seta- 
ceous tooth. The perichetium is a short branch of two or 
three pairs of erect adpressed leaves, of which the innermost 
has four or five lacinize. Calyx oblong bell-shaped, baving a 
deep division on one side. 
This most resembles the Chiloscyphus Endlicherianus
