On the Huon Pine, and on Microcacurys, a New Genus 
of Conirerzx from Tasmania ; together with Remarks upon 
the Geographical Distribution of that Order in the Southern 
Hemisphere ; by Josera Darron Hooker, M.D. R.N., 
Botanist to the Antarctic Expedition. 
(With a Plate. Tas. VI.) 
Long as the Island of Tasmania has been colonized by 
Europeans, its noblest trees, and those too belonging to that 
most readily recognized and important Natural Order (the 
“ Pines”), have, until quite lately, been little understood 
by Botanists. Whilst the continent of Australia was - 
known to possess numerous species of Callitris and Podo- 
carpus, and New Zealand has been celebrated as yielding a 
remarkable proportion of Conifere, Tasmania was generally 
Supposed to produce much fewer of these most useful trees. — 
Such, however, is not in reality the case;fortheislandinques- —— 
tion is now proved to contain a greater number of species in 
_ Proportion to its area, and these of more peculiar forms, than 
any other country. The fact of their having so long rem: ine 
unknown, or at least unrecorded, is mainly owing to the indi-
