 mities. 



cates that there are five cells to the ovary, and that the pistil is 

 formed of five carpels. In the Graminacege {fig. 587) and Gom- 

 positse {figs. 631 and 634), however, we have a bifid stigma, 

 and but one loculus or cell in the ovary ; this probably arises 

 from the non-development or abortion of the ovary of one of 

 the carpels. 



The lobes assume different appearances: thus, they may be 

 smooth, or thick and fleshy, as in the Melon {fig. 633) ; or fea- 

 thery, as in many Grasses {fig. 587), or fringed or laciniate, 

 as in Eumex {fig. 636).
