THE SPADIX OF ONE OF 

 THE CALLA LILIES 



From this direct-color photograph 

 it will be seen that the central stalk 

 within the lily, called the spadix, is in 

 fact a composite flower itself, on which 

 many minute and inconspicuous blos- 

 soms are clustered. Both these stami- 

 nate blossoms and pollen grains at the 

 top, and the pistillate ones lower down, 

 may be clearly seen.
