niid as tiicy do not pierce the flcin of the Receptacle, but raife a portion of 
its foft fijhftance with them, they grow up covered with this as a fkin. 
Thus is formed tire Filament, Fig. B, which confids of a quantity of 
the biefii of the Flan^ purely vafcular, covered with a reticulated loofe 
ikin, which is part of the white matter of the Conic Cluflers raifed into 
che Receptacle. 
Thus is formed the Filament ; and into its bafe run thofe fine Veflels 
which we fee arife from the protuberances terminating the Vafcular Series ; 
and running thro’ the Flefli of the Receptacle they go up the very fub- 
idance of the Filament, and accompany its Vtflels to the extremity. The 
fubdance of the Filament is to form the embryo Plant ; and the waxy 
Juice in thefe VelTels is to cover and defend it. An unripe Filament is re- 
preiented at Fig. 9. In the ripe Filaments we find the fummit formed into 
a regular oblong Anthera, compofed of two cylindric tubes, each wdth its 
proper groove for burding, and fadened to the tender top of the Filament 
toward its lower end, Fig. 10. 
The Anthera is thus formed. Toward the fummit the Filament be- 
comes final!, and at its very point there is another minute Gland, fome- 
what opake in hue, and full of cindering VelTels. This is reprefented 
vadly magnified at Fig. ii. A fmall cord furrounds it, formed -of the 
thickned coat of the Filament; and within, all the cluders of Fledi Vef- 
lels become again much fmaller. They are here at their extreme finenefs. 
From the fummit of this. Fig. i i. the coat of the Filament expands, and 
grows from the cord, 2, each way into a cylindric tube ; and thefe two 
tubes form the compleat Anthera, Fig. 12. which tho’ underdood to be 
only fixed upon the Filament, is in reality its proper termination. The 
Figure at 12 reprefents the Anthera ripe, but entire: that at 16, fliews it 
burd for the difeharge of the Farina: the intermediate Figures, 13, 14, 
13, (hew its progrefs from the Bud of the Flower to ripenefs. 
The outer furface of thefe two cylinders which compofe the Anthera, 
is all we have vet feen. It will be proper to cut one of them afunder tranf- 
verfely, to examine their condrudion. This gives us a view of the infide 
of the cylinders, which, according to the age of the Anthera, or its de- 
gree of ripenefs, appear in different conditions. In a very young one, 
taken out of a fmall Bud or Flower, the coat of the Anthera is feen to be 
double, with Veffels between. Fig. 17, and with a fmall hollow. In one 
yet more advanced, Fig. iB, there appear Bliders in the cavity. In one 
yet nearer maturity. Fig. 19, thefe Bliders fhew a regular elliptical diapc, 
and are fo raifed from the furface as to fill all the cavity. Thefe Bliders
