and flowers, and a new Bud is then formed at g, Fig. 4, the Rudiment of 
which is fixed on the oppofite fide of the Bulb. 
All this time the original Bulb remains. It is produced by the Root; 
and it produces nothing : it is to the infant Plant what the Placenta is to 
Foetus’s in the animal kinds ; a large body, of a flelhy fubftance, prepared 
to receive and detain Juices for the nutrition of the Embryo Buds. This 
folid part of the Root, which is the true Bulb, is reprefented fc-parately 
from the flowering part at Fig. 3. When it is cut thro’ perpendicularly, 
as at Fig, 4, there appear a few dufley lines, which makes it feem com- 
po.Qfd of fo many coats ; but the tranfverfe fedion. Fig, 5, fliews thefe are 
only courfes of Veffels. 
The new Buds for flowering flrike their firfl; Roots into the very fub- 
flance of this Bulb; piercing it to a third part of its thicknefs : this ap- 
pears by a peculiar white part in the Bulb near the Bud, Fig. 6, a. Thefe 
are utterly diflind from thofe Roots which the Bud forms afterwards, and 
thrufts into the ground : and this more diflindly proves, that the folid bo- 
dy of the Bulb is a Placenta, containing no Rudiment of a Plant, but af- 
fording nourifliment to the young Buds. 
All this is fhewn in the divided Flowering Plant, at Fig. 4, diflindly. 
The Bulb, /, is placed between two Rudiments, a b ; and being tui rowed 
on its furface, as is fliewn at Fig. 5, it makes a foft bed whereupon they lie. 
They are conneded with it at the head, whence the Fibres arife, and no 
where elfe. The I'lowering Shoot, b, has all its parts diflind ; and is fur- 
niflied by its proper Roots with nourifhment : the Shoot for the next year, 
a, is fiirniflied partly by its proper Fibres, and partly by the Roots it lends 
into the body of the Bulb, as at Fig. 6, a. The third is furniflied from 
the Bulb entirely. 
In the Flowering Shoot, b, there is united to the head of th.e Fibres, 
or proper Root, f, a fleflay bafe ; and from this is produced an oblong P>.e- 
ceptacle, of a foungy fubftance ; from which immediately rifes the Tube 
of the Flower, including in its bafe the Seed-VelTel, The Tube runs no 
to a confiderable height; and within it are carried up three leflTer Tubes, 
the three Styles of the Flower: all thefe are covered with many Films, 
which were the original defence of the ^ud : the outer ones decay and 
fade ; but the inner ones afterward grow out into Leaves, and ferve to de- 
fend the ripening Seed-Vcffcl. From the upper part of the Tube of the 
Flower rife fix Filaments ; which (hew the clafs of the Plant.
