366 HEPATICH ANTARCTICA. 
Hepatica Antarcrica; being characters and brief des- 
criptions of the Hepatica discovered in the southern 
circumpolar regions during the Voyage of H. M. Discovery 
Ships Erebus and Terror; by Dn. J. D. Hooker, and 
Dr. Tuomas TAYLOR. 
Waite engaged in preparing for the press other families 
of Plants collected during the recent voyage of Captain Sir 
James Ross in the Antarctic Regions; Dr. Taylor whose 
knowledge of the Hepatice is so universally acknowledged, 
has kindly assisted me in the investigation of those now 
under consideration; and in order that the public may 
derive advantage from it, we give a synopsis of the species 
in the present Journal, with some remarks, reserving more 
full observations and figures for the * Botany of the Antarc- 
tic Voyage,” now in course of publication. J. D. H.

The genus Jungermannia, L. at present consists of six. 
hundred and ninety-six published species, and itis conjec 
tured, of at least three hundred and four more undescribed, z 
but known to Botanists and preserved in their herbaria = 
We have thus, under a single genus one thousand species, 
which, perhaps, is without parallel in any other department í 
of Natural History. To relieve the memory, to facilitate 
arrangement, to give greater precision to communication | 
between Naturalists, and above all to define the groups ^" 
which nature composes this immense multitude, their Pro” 
perties and relations; these are strong and worthy motives 
to attempt the sub-division and analysis of such a gente 
Naturalists of first-rate talents have made the essay, Nees
