380 HEPATICZ ANTARCTIICA. 
Z 
Tufts wide, white above, pale-brown beneath. Stems from 
one to two inches high, usually unbranched, elongated, in- 
curved a little towards the summit. Although the stems 
are ascending, yet radicles issue from above the stipules 
throughout their entire length, whence it is possible that in 
situations where the stems are not tufted they may be alto- 
gether creeping and procumbent. The leaves are in two 
ranks, yet from their rising up they sometimes appear to be 
secund : they are widest about the middle, preserving, how- 
ever, an oblong figure ; they are emarginate, having an obtuse 
sinus and acuminated segments. It is rare to find a tooth 
on either segment of the stipules at their outward margin 
and towards the base. The perichetial leaves are upright, 
the two lateral do not differ in figure from the cauline; that 
corresponding to the stipules is nearly as large as the others. 
The calyx is delicate, nearly transparent, triangular, with the 
inferior side the widest, its angles are thickened and opaque 
the mouth has large spinous teeth and is divided into acute 
segments. The capsule is oval; the peduncle one quarter of 
an inch long, 
Of the European species, Jung. bidentata, L., is its nearest 
ally, from which its smaller size and entire segments of the 
stipules will readily distinguish it; but, it approaches much 
nearer to Jung. perpusilla, nob., from the same place ; it may 
be known, however, by its greater size, more considerable 
upright tufts, the deeper emargination of the leaves, their 
more acuminate segments, their greater cellules, and the 
deeper partition of the stipules. Be
