THE COMPOSITE 



The two carpels are inferred from the two-lobed stigma. 



Study the florets of the dandelion. Is there more than 

 one sort in the head ? Select a well-developed floret, and 

 describe it. Does your account agree with the following 

 schedule ? 



SCHEDULE FIFTEENTH. 



In the same way see how many sorts of florets you can 

 find upon the thistle-head, and carefully describe whatever 

 you find. Do the same for all the plants of this family 

 that you have collected. When a flower-head has both 

 disk and ray florets, note whether they are $ , ? , $ , or 

 neutral. 



When you have done this, you will be able properly 

 to apply the following terms to inflorescences of this 

 order : 



When all the florets of a head are perfect, it is said to 

 be homogamous. 



When part of the florets are imperfect, the head is said 

 to be heterogamous. 



Flower-heads are discoid when destitute of ray florets.
