HEPATICA ANTARCTIC. 377 
There is no European, or foreign Jungermannia, that ap- 
proaches the present in configuration. 
22. J. diplophylla, n. sp.; caule procumbente implexo sub- 
ramoso complanato, foliis distichis imbricatis patentibus 
ciliato-dentatis bilobis, lobis plica conduplicatis, lobo supe- 
riore minore ovato subacuto erecto-patente, inferiore late 
ovato obtuso patente, stipulis quadrato-rotundatis bifidis, 
segmentis sublinearibus ciliato-dentatis. 
Has. Lord Auckland's group. 
Patches from one to two inches in diameter, whitish-olive. 
Stems about one and a half inch high, with a few irregular 
branches. The duplicature between the lobes of the leaves 
is about one third of the length of the inferior lobe. The 
duplicature of the leaf next above is received within the du- 
Plicature of the leaf next below, consequently the upper 
lobes are imbricated in themselves, as are the lower lobes in 
themselves, 
The present would appear to belong to a new genus. It 
15 an example of a Scapania of Lindenberg; but having 
stipules! Yet, probably, the fructification is quite different ; 
for in a single instance, observed in a specimen from Mac- 
quarrie’s River, there was no calyx present ; the calyptra was 
globose, surmounted by a truncate style, rough with nume- 
rous barren pistilla on its surface and surrounded by 
numerous scales of which the interior were the narrowest, 
all of them laciniate and all enclosed in a triphyllous peri- 
chetium,
