its black colour, by its less acuminate perichzetial leaves, and 
principally by its entire stipules.

Has. Campbell’s Island. 
Tufts about one inch high, brownish-olive. Stems va- 
riously branched ; the branches erect. Leaves very concave, 
hence the shoots have a nodulose appearance, they are some- 
what decurrent, on which part the involute Jodulus is placed. 
Stipules nearly circular, and often appearing undivided, but 
pressure exhibits a narrow split. 
This is closely allied to Jungermannia serpyllifolia, Dicks., 
which does not appear to be an Antarctic species, and differs 
by its darker colour, more concave and more erect leaves, 
which too are somewhat acute, and have minuter and more 
densely placed cellules; besides, the segments of the stipules 
are by no means divergent.

Han. Lord Auckland’s group. is. 
Patches superficial one or two inches in diameter, by no 
Means tufted, very pale olive-green. Stems from two to 
three lines long, irregularly and distantly branched. Leaves 
embracing the stem, half-pitcher-shaped below, oblong and 
Tounded aboye, with the tops for the most part bending back, 
their structure is close with minute cells. Stipules closely 
^dpressed to the stems, so as to be observed with some diffi- 
culty, oblong, scarcely as wide as the stem. Perichetia of
