20. The Labiate or Irregular Flowers op the 

 FiGWORT Family — Figwort 



The plants. The Figwort family produces few early 

 flowers, but it happens that the type genus, figwort, blooms 

 in time for study. 



Observe the great resemblance of some of the stem and 

 leaf characters to those found in the mint family. Rub the 

 leaves, as in the ground ivy. What result do you have? 

 What is the inflorescence ? 



Flowers. Examine the separate flowers and observe the 

 odd form and arrangement of sepals and petals. What is 

 the color of each ? Find the number and place of attach- 

 ment of the stamens. 



Compare the flower, with its form and parts, with that of 

 the ground ivy. 



Examine the pistil. How do its parts differ from those 

 of the ground ivy ? How does the number of ovules differ ? 



Draw inflorescence and flower plan and flower, side view 

 and laid open to show stamens. 



What plan, if any, has the flower for pollination ? Do 

 all the flowers mature at the same time ? Do bees frequent 

 the plant ? 



Make a list of useful plants belonging to this family ; in 

 particular, foxglove, musk plant, mullein. Find some value 

 for each one on your list.

 equally good to show the profound modifications caused by 

 parasitism.
