178 VEGETABLE STRUCTURE. 
then into a Stalk ; and very foon the Rudiment of another Fruit is feen 
upon its top, and on the head of this, its own fmall Crown. Thus is the 
propagation of this Piant a mofl: clear inftance of what has been before af- 
ferted, that all Vegetable increafe, however the term Generation may have 
been applied to it in lome inftances, is nothing more than a continued 
growth. 
If we next fplit down a half-grown Pineapple with its Stalk, we fee 
its conflrudtion yet more diAindlly ; and may trace, with eafe, the origi- 
nation of the Fruit. A Pineapple in this ftate fplit thro’ the center with 
its Stalk, is rcprefented Plate XIV. Fig. 2. 1 he two Rinds, a b, make 
the furface of the Stalk ; within thefe runs up a pure Coat of Blea, c ; 
and in the midll are feen the Fle.^a Veflcls, d dy intermixed with more of 
the Blea. 
In this re(flion we fee clearly, that the Pineapple is not fo properly a 
Fruit fixed upon a Stalk, as a Stalk fwelling into a Fruit. To find how 
this is done, our attention mud be direcfled to the part e e, Fig, 2, where 
the Stalk ends and the Fruit begins. Here we fee plainly enough the con- 
tinuations of the feveral parts. The outer Rind thickens, and gives origin- 
to thofe fmall Bhlms, or imperfed: Leaves fffj\ which rife under the 
I’uberclcs ; the inner Rind, b by forms the Coat of the Tubercles, under 
which the Blea, c c, fwclls and expands into the body of the Fruit. A 
great quantity of it is fent up to this part, where it fv\ells and dretches out 
the Stalk into a kind of oval form, and ripening, becomes the delicate 
Pulp of the Fruit, g g. All this while the Flefh Vedels, d dy with their 
concomitant Icfier vafcular fydems run up drait thro’ the center of the Fruit, 
not feparating to any greater didance, but forming the fame kind of loofe 
column they did in the Stalk itfelf. The extenfion of the Blea is marked 
with the Letters gg, in Fig. 2, and the plain courfe of the Vefiels running 
up its center, at h by there is no difference between the Flefh Vefiels of 
the Fruit and thole of the Stalk, except that in the Fruit they are fmaller 
and more numerous, having divided at the part e Cy and fent off a few very 
delicate portions fideways and obliquely upwards, i /, which are to give 
origin to the Filaments within the Flowers lodged in the Tubercles, k k. 
This is the ftruflure of the Fruit of the Pineapple, whofe fmall 
Flowers are formed within thofe Tubercles, of all the parts, as in other 
Plants. But in the mean time that effential fubdance the Fledi of the 
Plant, which has continued its drait and upright courfe thro’ the Fruit, 
when it has reached the fummit forms a new folid Subdance, the Part /, 
which is the Rudiment of a new Plant, and from which rifes the Crown 
of
