288 HEPATICAE ANTARCTICA. 
Has. Lord Auckland's group. On bark. 
Tufts with variously entangled, flattish shoots, pale olive. 
Stems nearly two inches long, very irregularly pinnate. 
Leaves closely set, patent, appearing as if the segments were 
in whorls, divided into two or three deep segments, very 
rarely into four, such lacinie are not articulated but mi- 
nutely cellular. The stipules may easily escape detection, 
lying closely adpressed to the stem, and not exceeding it in 
diameter; they have usually three upright linear divisions. 
From Jungermannia tetradactyla, nob. above described, 
the present may be known by its shorter, more patent leaves, 
which, as well as the stipules, are usually trifid.

Of all the Mastigobrya of Nees the present most approxi- 
mates to M. Nove Hollandie ; it may be distinguished by the 
yellower colour of the entire plant, the more simple and 
greater stems, by the larger, wider, and shorter leaves, which, 
too, are not so closely imbricated, and by the wider cells 
which they are composed,
