VEGETABLE STRUCTURE. 
From the body of the Root, a c, which was its original part in the 
Sued, and in the Seedling Plant, its courfe downwards into the Fibres, I? by 
is plain, and it rounds them 2 i\. c c : afcending thence to the Crown of the 
Root, at d d, it enters the Leaf Stalks, e e, by a plain and fimple continu- 
ation in growth upwards ; but its afcent up the Stalk for flowering, is a 
matter of more delicacy : we fee it in this full-grown ftate of the Plant, 
afcending fimply up the Stalk, in a continued courfe from the Root, at fj] 
juft as in the Leaf Stalks : at ^ ^ it forms a flefhy lining of the two Films, 
which is here reprefented as it appears when ftripped of the inner Bark j 
and finally at h h it comes to an abfolute termination in the Petals. 
At /, the Flower, with its rudiment of a Stalk, is reprefented in the 
Bud ; but to fee this more diftindly we muft refer to the preceding Plate 
III. where, at the Letters / /, c c, d d, the conftrudion of the Bud, and 
courfe of this part are reprefented more at large j becaufe with all their 
part?, d he Bud />, lodged within the fliell by is encompaffed there by 
the Rinds and Blea. The Rinds fall off as the Bud rifes, as at c c ; and 
finally the inner Shell dy now expofed to the air, burfts alfo from the rif- 
ing of the Bud, in the fame manner. It might then feem that the Bud, 
■py fliould rife naked thro’ it : but Nature has contrived otherwife. 1 he 
whole inner Rind rifes in the Shell, c c, but the inner Shell, d, is not form- 
ed of the whole Blea, but is a duplicature only, rifing from the part g ; 
where the bafe of the Bud is formed upon the Flefli of the Root. There- 
fore the rudiment of the Stalk, which lies here, is covered with its pro- 
per Blea ; from the furface of which only rifes that portion of it which 
forms the Shell: and for this Reafon, when the Shell burfts as the Stalk 
rifes, its divided parts, c c, rifing with the Stalk as far as / niy there form 
the inner body of the two Films ; but the Stalk rifes cloathed with its Blea, 
from q to them, and above them, till it terminates at the three inner Petals. 
Thefe Petals, which being carefully folded over one another, form the 
head of the Bud, />, have therefore the extremity of the Blea upon them, 
when they pierce the Shell, dy formed of a duplicature of it, and after- 
wards forming the bodies of the Films.
