478 HEPATICA ANTARCTICA. 
valvis aut abnormiter disrumpens, seta suffulta. Hlateres 
spirales seminibus immixti. -Anthere frondi immerse. 
Frons pinnatim lobata.  Stirpes inter Jungermannias foliosas 
atque frondosas medie, his tamen multum affiniores.

Has. Cape Horn. Kerguelen’s Island. Long since re- 
ceived from Sir William Hooker, collected by Gardner 
in Brazil. Mr. Wilson has also found it in Dr. Hooker’s 
collection of Musci from the Falkland Islands. 
Fronds about two inches long, of a dusky green, in flat 
patches, linear; by transmitted light a reddish longitudinal 
axis may be observed. Lobes complanate, erecto-patent, 
somewhat imbricated, oblong; rotundate, entire, the cells 
large, their substance carnose yet thin. Involucrum formed 
of the hollow and swoln extremity of the frond, projecting, 
however, beyond it in a bilabiate top, lips submarginate. 
Capsule rotundato-ovate, usually irregularly dehiscent. In the 
young capsule seeds were observed, four joined together 
within the same transparent and colourless integument. 
Elateres very short, curled. Pedicel one inch long or a little 
more. The calyptra, irregularly burst and bearing a style on 
its summit, remains at the bottom of the involucrum. The 
anthers oblong-ovate are half buried in the substance of the 
frond, in a double, longitudinal series, pressed; they pour 
out a white oleaginous fluid. 
On the involucre or calyx, which curves upwards, are ob- 
servable two parallel, slightly raised, dentate wings. : 
This genus approaches the Fossombronia of Nees; but the 
structure of its involucre, in a great measure formed of the 
extremity of the frond, is quite dissimilar; so is the hor 
zontal position of the lobes. 
(Diplolena, Nees v. Esenbeck).

toma, lobis linearibus concaviusculis obtusis emarginatis -
