INTRODUCTION. 
When it is remembered that no fewer than one hundred and fifty new species of Hepatice 
were collected, and more than double that number required investigation, it will not be 
thought surprising that these minute and apparently insignificant productions should have 
proved to be among the most laborious departments of our Botany. The Zichens, not 
amounting to quite two hundred, and offering few undescribed species, have received a similar 
investigation from Dr. Taylor. 
In a hemisphere, of which the sea occupies so vast a proportion, the vegetable produc- 
tions of that element demand particular notice, and the Expedition in which I had the 
honour to serve being expressly of a maritime nature, a full collection of 4/ye was one of our 
first scientific objects. Dr. Harvey of Dublin, whose knowledge of this tribe is the result not 
merely of well applied talent at home, but of experience derived from two voyages and a pro- 
tracted residence in the Southern Hemisphere, has given me such aid in this department as 
no one else was competent to afford. There are sixty species from Lord Auckland’s group 
and Campbell’s Island alone; nearly twice as many from the other Antarctic Islands, and 
these, with the collections formed by Mr. Gunn in Van Diemen’s Land, in addition to the 
Alge brought home by the Antarctice Expedition, from New Zealand, and other quarters of 
the globe south of the Equator, swell the amount to between three and four hundred species 
requiring elucidation, a large number of which have not been hitherto described. 
So much attention was devoted to the Orders above enumerated, and more especially to 
the Flowering Plants, that but little time could be devoted to the Fungi. Some remarkable 
species were, however, collected, perhaps one hundred in all. These were at once placed in 
the hands of my friend the Rev. M. J. Berkeley, the first Mycologist of the day, and he has 
already forwarded to me the description of those from Lord Auckland’s group, twenty in 
number ; some of which are very peculiar, though not equally so with those found in the 
other Antarctic Islands, especially Tierra del Fuego.
