An Explanation of the different parts of fruclif cation. 



FRUCTIFICATION is a ttmporaiy 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. 



1. The Calyx, flower- cup, or empalement. 



2. The Corolla, petals, or painted leaves of the flower. 



3. The Stamina, threads, or chives. 



4. The Pijlihm^ or pointal. 



5. The Fericarpiim, or Seed-vefTel. 



6. The Seeds. 



7. The Receptacle, or bafe on which all the other parts of the 

 fru6lification are conneded. 



I. The calyx (which is the termination of the outer bark of 

 the plant, prefenting itfelf in the fruftification, in this 

 form) comprehends the feven following fpecies, viz. the 

 perianthium, the involucrum, the amentum, the fpadix, the glu- 

 ma, the calyptra, and volva, of each of which in their order. 



1. The perianthium, the flower-cup or empalement properly 

 fo called, is the moft common fpecies of calyx, and fltuated 

 clofe to the fruflification. If it enclofes the Jlamina and 

 germen, it is called the perianthium of the fruftincation. If 

 it enclofes the Stamina andnot the^erm^?i, it is ihQ perianthium 

 of the flower. If it includes the germem, and not the fla- 

 mina, it is the perianthium of the fruit. 



2. The involucrum or cover is fituated at the bottom of an um- 

 bel, at fomediftance from 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 thz 

 foot of a partial umbel. 



3. The amentum or katkin is that fort of calyx, which confifl:s of 

 a great number of chaffy fcales proceeding from a common 

 receptacle or (lender thread, as in hazel, alder, &c. 



4. 'Ihe Jpatha or Iheath is a fort of calyx which burlis length- 

 ways, and puts forth a flalk fupporting the flowers; as in 

 narcijjus, fnow-drop, arwn, indian turnep &c. 



5. The gluma or chaffy hulk, is that fort ot calyx peculiar to 

 graflfes, compofed of thin fcales or valves, w^hich are often 

 terminated by an arijia, a beard, or awn. 



5.. The calyptra a veil or hood, is a fort of calyx peculiar to 



moflTe?,
