number in the schedule. These parts are called carpels 

 (Figs. 118, 119). So, after the word "pistil" put carpels, 

 then style, and then stigma. The carpels shown in Figs. 

 1 1 8, 119 are from old ripe ovaries, and may be easily 

 counted. You can count them in Fig. 117, by the grooves 

 down the side, showing where they have grown together. 

 Sometimes they are not grown together at all, and so can 

 be easily counted. If the parts of the ovary are grown 

 smoothly together, count the styles ; and if these, too, are 

 united, count the lobes of the stigma. Or you may cut 

 across the ovary, as shown in Fig. 119, and count the cham- 

 bers or cells it contains, each of which is a carpel. Count 

 the carpels in the ovary of a lily, and compare the result 

 with the figure giving the number of carpels in Schedule 

 Sixth. 



EXERCISE XV. 

 Kinds of Calyx and Corolla. 



Fig. 1 20 represents a calyx in which the sepals are all 

 separate from each other, while in Fig. 121 a flower is 

 shown in which the sepals are all grown together. You 

 will find flowers that differ in this way, and many in 

 which the sepals are partly joined and partly distinct. 



FIG. 120. Polysepalous Calyx. FIG. 121. Gamosepalous Calyx. 



When the sepals of a calyx are distinct from each 

 other, so that each one can be pulled off separately, the 

 calyx is said to be polysepalous. 



A gamosepalous calyx has its sepals grown together by
