HEPATICZ ANTARCTIC. 287 
Has. Lord Auckland’s group. 
Patches shallow, creeping on other Hepatice or on Musci, 
pale yellowish-olive ; branches scarcely distinguishable by the 
naked eye, alternate, short, the flagelliform ones attenuated, 
their leaves distant and diminishing towards the ends. 
Cauline leaves closely set, patent, their segments not re- 
curved, their cellules large, obovate and divided above into 
four lanceolate segments, the undivided part cuneate. Sti- 
pules not wider than the stems, their divisions short. 
Our plant approaches, in character and habit, nearest to 
the European Jungermannia reptans, L. It is, however, 
much smaller, its leaves are not at all incurved or concave, 
their undivided portion or base less considerable, their divi- 
sion deeper, and themselves more closely imbricated. 
42, J. albula, n. sp.; caule subimplexo erecto ramoso, foliis 
imbricatis erecto-patentibus concavis late oblongis apiee 
quadrispinosis antice gibbosis dentatis, stipulis concavis 
rotundatis subsexfidis. 
Has. Lord’ Auckland's group; growing on Gotischea 
Lehmanniana, Lind. 
Stems thinly dispersed, very whitish-green, rather pinnate ; 
branches short, except when terminated with flagelliform 
Shoots. Leaves concave, their segments pointing forwards 
and thus imbricated, like a series of cups one within another, 
their cellules large, their anterior margin swelling out and 
dentate, the four segments or spines entire. Stipules about 
one-third the size of the leaves, imbricated, divided into 
six to eight lacinize. 
€ present is allied to Jungermannia Scolopendra, Hooker, 
as well as to Jungermannia hirsuta, Nees; both of these, 
Owever, have a hoary aspect, absent in our plant; besides 
their leaves are more erect and adpressed, while the segments 
are longer and narrower. 
43. J, hippurioides, n. sp.; caule czspitoso minuto procum- 
bente ramoso, foliis subimbricatis patentibus ex angusta 
basi bi-trifidis, segmentis linearibus acutiusculis, stipulis 
minutis erectis adpressis trifidis.
