HEPATICZ ANTARCTICA. 399 
vate, with five ribs or angles, very obtuse, terminating in a 
minute erect tube. 
The chief points of distinction between this and Jun- 
germannia serpyllifolia, Dicks., are the denser structure of 
the leaves, their recurved tops, the larger calyx, more naked 
at the base, and the rounder, more concave, and less erect 
pericheetial leaves. 
66. J. latitans, n. sp; caule disperso tenuissimo prostrato 
ramoso, foliis subimbricatis erecto-patentibus celluloso- 
crenulatis ovatis acutis, lobulis ovatis involutis, stipulis 
minutis bifidis segmentis lanceolatis obtusis, foliis perichee- 
tialibus acuminatis.

Patches very loose and shallow, very pale-green. Stems 
three or four lines long, creeping, irregularly branched. 
Leaves scarcely imbricated, on young shoots rather distant ; 
they vary in length, and in being acute or acuminate; their 
cellules are very large, especially towards the margin, 
Which has a rugged appearance, but it is not regularly cre- 
nate; the Jobulus only half as wide as the leaves. Stipules 
Scarcely wider than the stems. The perichetia are terminal 
9n the shoots of the preceding year, erect, obovate, all the 
pieces acuminate, the two lateral incurved, so that without 
careful observation the perichetium may pass for a bilabiate 
calyx, the third or stipular perichzetial leaf is concave, oval 
and bifid. 
The present resembles the Irish Jungermannia echinata, 
Tayl., but the leaves are not so regularly crenate ; besides, 
Stipules are present.
