456 HEPATICH ANTARCTICA. 
Scales, jagged at their summits. The margins of both lobes, 
as well as of the wing beneath, are slightly incurved. 
This species differs remarkably from the rest of the Gott- 
schee of Nees, by its carnose structure. 
4. J. pachyla, n. sp.; caule cespitoso erecto subramoso — 
apice incurvo; foliis imbricatis erecto-patentibus lobis 
ovato-oblongis acuminatis, dorsali apice incurvo integer- 
rimo, ventrali horizontali margine anteriore dentató-apice 
subincurvo, stipulis majoribus ovato-acuminatis bifidis, 
segmentis lanceolatis. ; 
Has. On exposed moist banks, Hermite Island, Cape Horn. 
Roots, as in all this tribe, simple, thick, purple. Tufts - 
loose, reddish dark-brown. Stems two inches high, erect. 
Shoots thick, slightly incurved at their tops. Leaves closely —— 
imbricated, their lobes joining by about one fourth of their 
length, placed at an acute angle one on the other and in the 
angle receiving the duplicature of the leaf next above; their 
margins are uneven and the anterior part of the lower has - 
three or four large teeth with a deep sinus between them. The 
stipules often have their segments unequal, entire but with 
an uneven outline. is 
This species is more nearly related to the preceding than 
to any other Gottschea of Nees: it is distinguished by 1s 
smaller size, its shorter leaves, their lobes with a shorter 
commissure, its stems less compressed and by having the. 
margin of the lower lobe dentate. 3 
5. J. laminigera, n. sp. ; caule cespitoso erecto ramoso com 
presso, folis imbricatis patentibus ciliatis, lobo ventrali c 
lanceolato basi bilobo, dorsali semicordato, utroque cristas. ; 
dentatas lineares undulatas ferente, ut et stipulis majori- ; 
bus rotundatis quadrifidis ciliatis, calyce terminali oblongo — 
compresso, cristas dentatas undulatas ferente, ore laciniato 
ciliato. 
Has. Hermite Island, Cape Horn. wu 
Tuftsloose, very pale tawny-green above, brownish be- 
neath. Stems three inches high, the branches erect, fasti- - 
giate. The leaves bear toothed and waved crests that fre- 
quently terminate at either end without reaching the margins.
