472 HEPATICZ ANTARCTIC. 
apice trifido, segmentis emarginato-bidentatis, subinteger- 
rimis. 
Has. Cape Horn. 
Patches wide, pale but dusky olive-green. Stems two 
inches long. Leaves scarcely imbricated, nearly patent, 
having a narrow neck previous to dividing into two subulato- 
setaceous segments with a very obtuse sinus between them. 
Stipules minute, about as wide as the stem. Pericheetial 
leaves erect, the two lateral dentate as well as emarginate, 
the third or stipular bifid, entire. Pedicel one inch long. 
Capsule oval. 
The Lophocolee of Southern Regions are very closely 
related, yet very minute but constant marks of discrimination 
may be detected between them. The present differs from 
our J. secundifolia, by the leaves being complanate, not 
secund ; from our J. diademata, by the less patent leaves, 
and from our J. physanthe, by the elongated calyx; and from 
all three by the segments of the mouth of the calyx being 
emarginato-bidentate. 
41. J. humifusa, n. sp.; caule implexo procumbente ra- 
moso, folis approximatis erecto-patentibus complanatis ob- 
longis antice gibbosis emarginato-dentatis cceterum integer- 
rimis, stipulis bipartitis segmentis subulato-setaceis extus 
unidentatis. 
Has. Kerguelen's Island. 
Patches wide, very pale green. Stems about an inch long; 
irregularly branched. Leaves approximated, but not imbri- 
cated, having broad decurrent bases; their emargination 1S 
very irregular, especially in the inequality of the segments. 
Stipules sometimes with a setaceous process at each side run- 
ning back from their insertion along the stems. 
This approaches nearest to our J. leptantha, from Cape 
Horn. Its leaves are more erect, have larger cells, their — 
emargination is more irregular, their bases wider and more 
decurrent, while the stipules have their segments mo?  — 
setaceous.
