 inside the corolla come the stamens, and within these the 

 pistil. If there is but one circle of flower-leaves it is called

a calyx, whatever its color. Point out and name the differ- 

 ent circles that compose each of the flowers you have gath- 

 ered. But each of these flower-circles is made up of parts 

 of the greatest importance in the study of plants, and these 

 parts must be found and named. Each leaf of a calyx is 

 called a sepal (Figs. 112, 113). Each leaf of a corolla is 

 called a petal. When these circles form a perianth, its parts 

 are called leaves. 



Before finding any more parts to name, you may be- 

 gin to note down and number the parts already found.

Prepare several flower -schedules like Schedule Fourth. 

 The first point to be looked for and written down con- 

 cerning a calyx or a corolla is the number of sepals OT
