THE CALYX. 



.5. Pericarpium, seed-vessel. 



t 



6. Semina, the seeds themselves. 



7. Receptacle*, base, on which the fructification is seated. 



All these parts, and their several uses, will be particularly ex- 

 plained in the following chapters ; and it is sufficient to observe 

 here, that the four first, viz. Calyx, Corolla, Stamina, and Pistil- 

 lum, are properly parts of the flower ; and the three last, Pericar- 

 pium, Semina, and Receptacle, parts of the fruit ; and that it is 

 from the number, proportion, positions, and other circumstances 

 attending these parts of fructification, that the classes of vegeta- 

 bles, and the genera they contain, are to be characterized accord- 

 ing to the Sexual System. 



CHAP. II. 

 OF THE CALYX. 



THE Calyx is, according to Linnceus, "the termination of the 

 cortex, or outer bark of the plant ; which, >&fter accompanying 

 the trunk or stem through all its branches, breaks out with the 

 flower, and is present in the fructification in this new form/' Its 

 chief use is to enclose and protect the other partsf. It has re- 

 ceived different appellations, according to the circumstances with 

 which it is attended, viz. 



1. Perxanthium, a flower-cup, when its station is close to the 

 fructification. If it includes the stamina, and not the germen,

 tany/' Editor. 



f- It sometimes serves the office of pericarpium, as in the Lamium, nettle, 

 and frequently accompanies the fruit. In the Patagonula and egg- plant it is ob- 

 served to grow to a larger size in the fruit than it had in the flower. Editor.
