Dissections of flowers of Lychnis diurna. I., II., VIII., the pistillate flower in 

 which the stamens are represented only by staminodes (st). III., IV., IX., the 

 pistillate flowers in which the gynoecium is represented only by a vestigium (gyn). 



The fruit is a dry capsule, which opens by teeth at the distal end (Fig. 

 47 1 . VII.), and the numerous curved, albuminous seeds are scattered as it is 

 shaken in the wind. 



The products of the Order are unimportant . It is related to the Goose- 

 foot Family (Chenopodiaceae). 



ORDER: POLYCARPICAE. 



Family : Ranunculaceae. Examples : Marsh-Marigold, Buttercup, 



Monkshood. 



The Buttercup Family is relatively primitive, as indicated by the variability 

 of its floral construction, by the number of its parts, and the character and
