pend, prove, on a nearer examination, total ftrangers, 
with other configurations, other ceconomy, and other 
qualities ; ‘ not only all the fpecies that prefent them- 
felves are new, but mofi: of the genera, and even natural 
orders. 
The plant before us juftifies the above rem^ks. Its 
botanical chara6ters are fo new, we can fcarcely tell to 
what tribes it is allied ; and although, from the peculiar 
felicity of the I>inncean fexual fyftem, founded on parts 
which every plant 7 ?iujl have, we are at no lofs to find 
its clafs and order in that which is an artificial fyftem, 
we ftill fcarcely know what genera are its natural allies. 
It, however, feems moft nearly related to 'DiSiamnus and 
Ruta^ of all the Decandria Monogynia, and may be 
fafely inferted near them. We dare not pofitively fay 
it belongs to M. De Juffieu’s natural order of Rutacea^ 
but for the prefent it may be fo confidered, till future 
difcoveries fliall authorife us to conftitute a new one. 
The generic charadfer above given certainly diftin- 
guiflies it from all other genera, and the name applies 
to the very unufual horn-like divifions of the petals? 
like thofe in th^ leaves of the Ceratophyllmn of Linnseus., 
One fpecies only is already known. 
This, Mr. White informs us, is one of the trees (for 
there are feveral, it feems, befides the Eucalyptus refini- 
fera^ mentioned in his Voyage, p. 231.) which produce 
the red gum. He further remarks, that it is the only 
wood of the country that will fwim in water.
