HEPATIC’ ANTARCTICA. 469 
- Patches wide, very pale yellowish-green. Stems 2 inches 
long, matted together. Leaves in the same plane, their 
structure largely cellular, their anterior margin curved, the 
posterior straight and at an acute angle with the stem. 
Stipules wide as the stem, bipartite, the segments acumi- 
nated. Perigonia occurring sometimes in the course of the 
stems, usually at their tops, their leaves closely adpressed, 
erect, with tumid bases. 
The present resembles our J. planiuscula in the large 
cellules of the leaves, but differs by its much smaller size, 
shorter semiovate leaves, and by the more entire segments 
of the stipules. ; 
34. J. sabuletorum, (n. sp.); caule czespitoso adscendente 
ramoso apice recurvo, folis approximatis patentibus secun- 
dis subquadratis integerrimis apice subexcisis, stipulis minu- 
tis lanceolatis bipartitis, segmentis subulatis incurvis. 
Has. Falkland Islands. 
Patches about 2 inches wide, pale tawny. Stems scarcely 
one fourth of an inch high, rising upright till they overtop 
the wet sand on which they grow, then reclining back and 
becoming horizontal. Leaves in five or six pairs, when 
moistened becoming homomallous, they are usually slightly 
notched or indented, more rarely rounded at their tops; 
their cells are very large. The top of the shoot is flattened 
by the terminating pair of leaves being compressed. 
This, perhaps, is the minutest of this tribe of the Junger- 
mannie ; the rotundato-quadrate figure of the leaves with 
their shallow and wide sinus appear sufficiently to discrimi- 
nate it from the other Lophocolee.

Haz. Port Louis, Falkland Islands. | 
. Tufts loose, the inferior part apparently submerged, black- 
Ish-brown, the upper very pale olive-green. Stems nearly 
2 inches high, with a few ascending or erect branches,
