88 HEPATICÆ ANTARCTIC. 
Perigonia short, twice as wide as the shoots. Stipules scarcely 
wider than the stems.

Has. New Zealand. On Lichens. 4 
Patches loose, reddish-brown. Stems scarcely 1 inch 
long. Leaves with the edges frequently scariose and whitish. 
Calyx large in proportion to the diameter of the shoot, with 
two acute folds above and one ventricose below, half im- 
mersed in the perichetium. Allied to Frullania crassiuscula, | 
Tayl, from Demerara. It is, however, smaller, less green, 
and the auricles are far more slender, acuminate and deflexed. -

Scarcely one quarter of an inch long, pale green, sometimes | 
brownish-purple. Stipules large, their emargination shallow : 
and rounded. Auricles large, compared with the leaves. The - 
calyx, rising little out of the perichætium, is widest near the 
mouth, below which it is rather suddenly contracted. E i 
lateral perichætial leaves have, besides a segment correspond- 
ing to the auricle of the leaf, an inner one which is lanceolate 
and dentate. Allied to Frull. trinervis, L. et L., but this! is 
of a dark brown colour, has a more exserted iren ; 
calyx, the auricles are less acuminated, and the stipules more 
entire. 3
