This has a good deal of resemblanee to the J. coriifolia. Hook., of Britain, but the presence of stipules will
at once distinguish the Antarctic plant. In many respects it has an equal claim to he considered a Lopiiocolea as a
Jmigennannia ; on the w-hole, however, we incline to retain it iu the latter genus.

A very beautiful species, albed to onr / . iiplopJiglla (Pt. 1. p. 1B2. t. 64. f. iv) ; where fructification is unknown,
they together appear to fonn as natural a genus as any which has been proposed out of Jungermannia, and dificé
from Scapania in the presence of stipules. The present is readüy distinguishable from J. diplopjajlla by the separation
of the two lobes of the leaf, by their emarginate tips, by the larger and closer cibation of their mai-gins and by
the less deeply bnt more frequently divided and broader stipules.

Possibly from its rather anomalous locabty, an altered state of some other species, though we cannot say of
what. In the wet place of growth, erect habit and general outbne of the leaf, it resembles the British / . Lyoni,
Tayl. ( /. socia. var., Gottsche, Lind, et Nees), difl'ering in the paler green colom- of the young shoots, in the
more debcate fobage, smaUer areolæ, deeper emargination and clasping leaves.

A very curious species, and unbke any witb which we ai-e acquainted. The habit of the Falkland Island specimens
when dried, is, owing to them liavhig gi-ow-n in water, so pecnbar, that w-e regarded them at first as a
ibfl'ercnt species, wlbch we described as J. cavispina, from the reflexed margins of the closely imbricating stipules,
giving a gi-ooved appearance to the back of the stem. The calj-x is that of a Lopiiocolea, from which group the
presence of stipules aud the entfre leaves remove it.
