pala; Xylomelum, and Lambertia are readily distinguished from 
Embothrium, Grevillea, and Hakea; and thus also Persoonia and 
Brabejum remarkably differ from Gevuina; while Bellendena differs 
from all others in having its stamina distinct from the calyx, 
affording however an indication of the real origin of these 
organs in the whole family. | 
The deviations from the usual structure of ANTHER in this 
order are not many; but some of them. are of so singular a 
nature as to constitute the essential characters of the genera in 
which they take place. These genera are Simsia, Conospermum, aud _ 
Synaphea, all of which are most truly syngenesious; for not only 
do their anthere firmly cohere together, but the corresponding 
lobes of these being, when considered separately, entirely open, 
are so applied to each other as to form but one cell, without a 
trace of any intermediate membrane. In Simsia the four anthere 
are perfect, each consisting, as in the rest of the order, of two 
lobes, and therefore the whole before bursting coustitute four 
cells. Whereas in Conospermum and Synaphea one filament is 
entirely barren, the two lateral ones have each a single-lobed 
anthera, and the fourth alone is perfect: hence before bursting 
the whole form only two cells. 
_ This remarkable structure, which can only be ascertained be- 
fore the opening of the calyx, necessarily escaped Dr. Smith in 
describing his Conospermum, for Í conclude he had only the ex- 
panded flower before him, and the appearance of the antherz in 
this state after their separation justifies him in referring the genus 
to Tetrandria: but according to the view now given of its struc- . 
ture, it can have no other pretension to a place in this class than 
its belonging to Proteacex ; and the order Syngenesia Monogamia 
being abolished, it must be referred to Triandria. =
