— BEFORE proceeding to describe the Cryptogamic Plants of the Antarctic Expedition, it may be proper to state, that 
s group they received a larger share of attention during the progress of the voyage than is usually paid to those Orders 
ds, and which can only be satisfactorily collected by one accustomed to distinguish the species both microscopically and in 
TU the field. As might be expected, the amount of new genera is much smaller than among the Pheenogamic plants, 
and even some of the well-known forms of Europe occur : whilst, however, this general similarity to the productions 
artes of of other countries tends to diminish the interest of the collections, the great proportion which such tribes bear to the 
| species more highly organized plants in these latitudes, adds considerably to their importance in geographic Botany. Thus, 
though there are only a hundred and twenty-four flowering plants in Lord Auckland’s group and Campbell’s Island, 
there are two hundred and fifty Cryptogamiz ; a number which could not fail to offer a large amount of new species 
cially to and many genera of peculiar interest. 
narkable Of the Mosses, however, I may remark, that the two principal groups, Acrocarpi and Pleurocarpi, bear that. 
laced in : certain proportion to one another which follows a fixed law throughout the globe; the former increasing with the 
Th latitude over the latter; for these not only decrease in number more rapidly, but also in development, seldom fruiting 
y . in low temperatures. The humid, temperate and shady islands of the Southern Hemisphere promised at first sight 
venty m to be richer in species than investigation proved them to be; this arises from a remarkable luxuriance and diffusion 
jn the in the individuals. In no part of the world have I been able to collect as many species in a week as during one day’s 
search in many districts of Scotland; a difference too marked to be attributable to my greater familiarity with the 
species of our own country.

The peduncle, which elevates the mature capsule in this genus, is nothing more than an elongated receptacle 
(pseudopodium, Brid.) of a white colour; such as is also found in Sphagnum. In an early stage, this receptacle scarcely 
differs in appearance from that of other mosses ; by its subsequent elongation the theca is elevated, generally above
