82 HEPATICZ ANTARCTIC, 
of a bird's wing, that is, oblong with a shoulder in front, 
their outline towards the top very irregular; scarcely notched, 
an odd obtuse tooth is sometimes visible, each pair is decur- - 
rent to the same point of the stem. Stipules subquadrate. - 
Of the upper leaves, near to the calyx, the margin on one - 
side is often confluent or connate with the stipule.  Periche- 
tial leaves erect, dentate. | 
Our plant bears so strong a resemblance to Jungermannia — 
heterophylla, Schrad., that it is with some distrust now sepa- - 
rated, on account of the more rotundate figure of the leaves, - 
and their larger cells and because of the longer calyx — 
whose lips are more frequently and more deeply toothed, as — 
are the perichætial leaves. :

Tufts dense, short, the older parts purplish-brown, n ; 
younger paler. Stems scarcely half an inch high, slender; - 
variously bent. Leaves with an amplexicaul base, concave - 
the summits bent in towards the stem, the margins of the - 
segments slightly recurved. Stipules scarcely wider than the — 
stems. The present may be known from our Jung. perpusilla — 
by the narrower leaves, with segments more deeply divided, - 
more acuminate and introflexed, and by the somewhat wider - 
stipules which have occasionally a tooth exteriorly on each - 
segment, near to the base. f
