landia, and consists in the anthera, or rather that portion of the 
filament on which it is fixed, adhering to the calyx through its 
wbole length. 
The figure of the porteN has been attended to by a few ios 
retical, but by hardly any practical botanists; yet I am inclined 
to think, not only from its cohsideration in this family, but in 
many others, that it may be consulted with advantage in fixing 
our notions of the limits of genera: and though its minuteness 
may perhaps always exclude it from a place in generic characters, 
yet it well deserves, to use the words of Linnazus sten speaking 
of habit, to be ** occulte consulendus." - | 
Its usual figure in the order is triangular with secreting angles, 
a beautiful contrivance for insuring impregnation in a tribe, in 
which, from the very scanty, or in many cases apparent want 
of secretion by the stigma, it must otherwise have been very 
uncertain; for by this form and secretion, as well as by the sin- 
gular ceconomy of the calyx, it remains so long in contact with 
the stigma, as probably to compensate for the somewhat de- 
fective structure of that organ. — ; 
From this figure the principal deviation is in the extensive 
genera Banksia and Josephia, in all of which it is elliptical or 
oblong, and either straight or bent into a semilunar form; 
and in Franklandia and Aulax, where it is spherical. The only 
remaining exception with which I am acquainted is the original 
Embothrium of Forster, his E. coccineum, in which, as in Banksia, 
it is oblong; a circumstance that, together with the more im- 
portant character of a regular club-shaped stigma, and some 
other differences, has determined me to separate it from all the 
other species of Embothrium, except E. lanceolatum of are Peru- 
viana, whose pollen however remains to be examined. - |
