OP THE CALYX AND COROLLA. 43 



67. Next within the perianth of the Lily we find six long, 

 slender organs of peculiar form and color, called stamens. 

 In the Rose you find a larger number (perhaps one hundred) 

 of stamens, while in the Speedwell you find but two. But 

 the most common number is five. Count them in the Morn- 

 ing-glory, the Bellwort, Primrose, &c. 



68. Lastly, this central, club-shaped body (p), here as long 

 as the stamens, but of totally difi'erent structure, is\iiepistil. 

 Other flowers have more than one pistil, as the Pink, which 

 has two ; the Hose, which has many ^^ 



69. Thus, we have learned that the flower — at least this 

 flower — is compounded of four kinds of organs, those of 

 each kind being arranged in a circle by themselves. The 

 outer circle, of sepals, constituting the calyx; the second 

 circle, of petals, constituting the corolla; the third circle, 

 the stamens ; the fourth circle, the pistils. 



LESSON XII. 



MORE ABOUT THE CALYX AND COROLLA. 



YO. Let us examine the flower of the Pink (Fig. 112), the 

 Strawberrj' (Fig. Ill), the Crowfoot, the Single Rose. In 

 either you observe five green sepals, and the same number 

 of colored petals. Notice also the positions of those organs, 

 — how the petals stand alternating with the sepals, and that 

 they are all distinct and separate. This is the general rule, 

 but there are many exceptions. 



67. Lastly, review the whole arrangement. 



70. What is the rule as to the number of petals and sepals ? What is the 

 rule as to their relative position, &c. ?
