cation ; like Saxifrage* also it comprehends genera with ovarium superum 
and inferum. . 
The genera strictly belonging to Cunomacem are Weinmanma, 
Cunonia, Ceratopetalum, Calycomis, and Codia. To this order R tu ra 
may also be referred, but it must form a separate section from the genera 
already mentioned. Of these Wemmannia, Ceratopetalum, and Calycomis 
are found in Terra Australis, and hitherto, only at the eastern extremity of 
its principal parallel, where also Bauera is most abundant ; but this genus 
is found beyond the parallel in one direction, extending to the southern 
extremity of Van Diemen’s Island. 
RHIZOPIIOREiE.* The genera Rhizophora, Bruguiera, and Ca- 
rallia, all of which are found in the equinoctial part of New Holland, iorm 
a distinct natural order which may be called Rhizophorece. This order agrees 
with Cunoniacese in its opposite leaves and intermediate stipule, and with 
great part of them in the estivation of its calyx, and in the structure and 
cohesion of the ovarium. From these it differs chiefly in the want of Albu- 
men and greater evolution of its Embryo. Jussieu t has combined Rhi- 
zophora and Bruguiera with Loranthus and Viscum, neglecting some very 
obvious, and, as they appear to me, important differences in the dower, 
and probably never having had an opportunity of comparing the very dis- 
tinct structures of their ovaria ; the affinity too of Rhizophoreae to Cuno- 
niaccte is unquestionable, and it will hardly be proposed to unite both 
these tribes with Loranthus, which I consider as even more nearly related 
to Proteace*. 
HALORAGEA3. The greater part of the genera of which this order is 
composed, have been referred to Onagrare«,to certain parts of which they 
no doubt very nearly approach ; but it must appear rather paradoxical to 
unite Fuchsia in the same family with Myriophyllum and even llippuris,
