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 moft of the genera, and even natural 
orders. 
The plant before us juftifies the above remarks. Its 
botanical characters are fo new, we can {carcely tell to 
what tribes it is allied; and although, from the peculiar 
felicity of the Linnsean fexual fy{tem, founded on parts 
which every plant uf? have, we are at no lofs to find 
its clafs and order in that which is an artificial fyitem, 
we {till {carcely know what genera are its natural allies. 
It, however, feems moft nearly related to Dicfamnus 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 Rufacea, 
but for the prefent it may be fo confidered, till future 
difcoveries fhall authorife us to conititute a new one. 
The generic character above given certainly diftin- 
guifhes it from all other genera, and the name applies 
to the very unufual horn-like divifions of the petals; 
like thofe in the leaves of the Ceratophy//um of Linnzeus. 
One f{pecies only is already known. 
This, Mr. White informs us, is one of the trees (for 
there are feveral, it feems, befides the Eucalyptus rejini- 
jfera, 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 {wim in water.
