456 HEPATIC ANTARCTICA, 
This species reminds one, in the figure of its leaves and - 
their connexion in front, of Jung. Brankiana Nees; this 
however is destitute of stipules. 
26. J. otiphylla, n. sp.; caule aggregato elongato erecto 
subramoso debili, foliis imbricatis flaccidis tenuissimis erecto- 
patentibus elongato-reniformibus margine recurvis integerri- 
mis, stipulis majoribus concavis rotundatis emarginatis. 
Has. Alpine bogs, Hermite Island, Cape Horn. 
Tufts loose, dusky whitish-olive. Stems 3 inches high, 
sparingly branched, the branches erect. Leaves very thin and 
flaccid, easily retaining any position in water in which they 
may have been placed, oblong, but before joining the stem 
above and below rounded like the human ear. Stipules 
large, subimbricated, their margins incurved, their tops emar- 
ginate with a very obtuse and shallow notch. 
The present approaches our J. palustris from the same 
country, and from similar situations; but the leaves have not 
the inflated structure and folds, nor the entire stipules of 
that species, besides the foliage is more closely imbricated, 
and more colourless and transparent. : 
27. J. austrigena, n. sp.; caule laxé cespitoso elongato 
adscendente ramoso, surculis incurvis, foliis imbricatis erecto- 
patentibus subsecundis rotundatis convexis integerrimis, stl- 
pulis majoribus rotundatis apice bidenticulatis, calyce termi- 
nali oblongo compresso trigono, ore subintegro. 
Has. On moist banks, Hermite Island, Cape Horn. 
Patches loose and wide, whitish and yellowish-green. 
Stems 3 inches long, variously branched and /flexuose. | 
Leaves closely imbricated, slightly decurrent in front. Sti- 
pules round, entire, except at the very summit, where usually 
two very minute teeth appear under the lens. Calyx large, 
oblong, wide, variously twisted, having three sides, of which 
the inferior is the widest, while the two upper meet at? 
ridged angle. po 
This species, unlike any other hitherto described, has the 
calyx of a Lophocolea (Nees), from which tribe it is removed 
by its entire leaves and stipules. EC
