ARUM FAMILY 69 



Cabbage and the Jack-in-the-pulpit, as well as the 

 cultivated Calla of the greenhouse and window 

 garden. Standing erect in the middle of the blos- 

 som is the cylindrical spadix bearing the numerous 

 minute florets of a greenish yellow color, and 

 surrounding it is the large white spathe with its 

 pointed tip which gives the flower its chief attrac- 

 tiveness. The thick and succulent heart-shaped 

 leaves are pointed at the tip. The plant is most at 

 home in northern regions in cool bogs and along 

 the borders of shallow, sluggish streams in the 

 woods, where it is often very abundant.
