An Explanation of the different parts of Iruclification. 
F RUCTIFICATION is a temporary part of vegetables, 
appointed for the purpofe of generation, terminating 
the old vegetable and beginning the new. The parts of fruc- 
tification are the feven following, viz. 
i. The Calyx, flower- cup, or empalement. 
2. The Corolla, petals, or painted leaves of the flower. 
3. The Stamina, threads, or chives. 
4. The Pijlilum, or pointal. 
5. The Pericarpium, or Seed-vefifel. 
6. The Seeds. 
7. The Receptacle , or bafe on which all the other parts of the 
fructification are connected. 
I. The calyx ("which is the termination of the outer bark of 
the plant, prefenting itfelf in the fructification, in this 
form) comprehends the feven following fpecies, viz. the 
perianthium , the involucrum, the amentum, the fpadix, the glu - 
ma, the calyptra 9 and volva, of each of which in their order. 
1. The perianthium , the flower-cup or empalement properly 
fo called, is the mod common lpecies of calyx, and fituated 
clofe to the fructification. If it enclofes the Jlamina and 
germen, it is called the perianthium of the fructification. If 
it enclofes the Stamina andnot the germen, it is the perianthium 
of the flower. If it includes the germem , and not the Jla- 
mina, it is the perianthium of the fruit. 
2. The involucrum or cover is fituated at the bottom of an um- 
bel, at fomediftancefrom the flower. It is called an univer- 
fal involucrum or cover, if it is fituated at the bottom of an 
univerfal umbel; and a partial involucrum or cover, if at the 
foot of a partial umbel. 
3. The amentum or katkin is that fort of calyx, which confifts of 
a great number of chaffy fcales proceeding from a common 
receptacle or flender thread, as in hazel, alder, &c. 
4. The fpatha or flieath is a fort of calyx which burfts length- 
ways, and puts forth a (talk fupporting the, flowers; as in 
narcijjus, fnow-drop, arum, indian turnep &c. 
5. The gluma or chaffy hulk, is that fort of calyx peculiar to 
graffes, compofed of thin fcales or valves, which are often 
terminated by an arijla, a beard, or awn. 
6, The calyptra a veil or hood,, is a fort of calyx peculiar to 
modes.
