SECTION II. 



NOMENCLATURE OF THE FLOWER. 



1. The flower has beeu described, as a temporary 

 part of the plant, consisting of the calyx, the corolla, 

 the stamen, the pistil, the receptacle, the nectary, the 

 seed-vessel, and the seed. 



We shall first explain the botanical terms, applied to these re- 

 spective parts, then speak of the characteristic names of flowers, and 

 finally, of their manner of blooming, or inflorescence. 



OF THE CALYX. 



2. There are se\ en different kinds of calyces, viz. 

 the perianth, the fence, the catkin, the sheath, the 

 glume, the veil, and the curtain. 



THE PERIANTH OR FLOWER-CUP. 



3. The perianth is characterized, from the number 

 of its leaves, the division of its margin, its disposition to 

 the germen, the number on each flower, its situation 

 with respect to the fructification, and its duration. 



4. Number: From the number of leaves, by which 

 a perianth is formed, it is called monophyllous, diphyl- 

 lous, and so on, according to the number. 



a. Monophyllous when formed only of one leaf, as in the 

 primrose. 



b. Diphyllous when formed of two leaves, as in the common 

 poppy. 



c. Triphyllous when formed of three leaves, as in the dock.
