 be separable into calyx and corolla.

 the corolla.

 Calyx. ^xis^ sepal. 



SE'PAL. One of the leaves of the calyx. 



NOTE. The first thing in studying the flower is to become 

 acquainted with its leading parts and their names. This is 

 done by comparing numerous specimens with Fig. 175. The 

 pupil is then ready to begin work with the flower schedule. 

 Figs. 177 and 179 are given to assist the pupil in answering the 

 first questions upon it. Write under the question, calyx? the 

 names of the parts that compose the calyx, and under the question, 

 corolla? the names of the parts that compose the corolla. Then 

 count the sepals in your flower, and write their number after 

 the word sepals, in the next column ; count also the petals in 

 the corolla, and write their number after the word petals.
