FIG. 11. 



Achlamydeous Flower. 



Achlamydeous flowers are said to be naked. 



After observing the pictures, and reading the defi- 

 nitions of this exercise, you may find upon the charts 

 all the pictures of dichlamydeous flowers ; of mono- 

 chlamydeous flowers ; of achlamydeous, or naked, 

 flowers. Then look over your living specimens again, 

 putting the dichlamydeous ones by themselves ; the 

 mqnochlamydeous ; the achlamydeous. Pay no at- 

 tention to the doubtful instances ; there will be fewer 

 and fewer of these as your observations proceed.

 and mantle, having two coverings, calyx and corolla. Both 

 calyx and corolla,

 gle and cloalc, having a single covering; that is, a calyx without
