THE FAMILIES OF FLOWERING PLANTS 

 By Chaeles Louis Pollaed. 



CHAPTER XXY. 



Order Pariefahs. 



The name of this order is taken from a Greek word meaning ivall, 

 on account of the fact that the ovule-bearing surfaces (i)lacentae) are 

 attached to the walls of the ovary instead of forming a separate column. 

 This condition may be plainly 

 seen by sectioning the capsule 

 of a violet or pansy. The 

 ovary in this group is com- 

 pound, and the stamens almost 

 always numerous. It contains 

 thirty-one families, many of 

 them small and not well 

 known; the most important 

 ones are the Theaceae, Hyper- 

 icaceae, Guttiferae, Cistaceae, 

 Violaceae, Dipterocarpaceae, 

 Passifloraceae, Caricaceae and 

 Begoniaceae. 



Family Dilleniaceae. Dil- 

 lenia Family. A group con- 

 taining about 30 genera and 

 250 species, consisting of trees 

 or shrubs widely distributed 

 in Australia, Indis, and some 

 parts of South America. They 

 may be distinguished by the 

 five persistent sepals, borne in two rows, the five deciduous petals, inid 

 the numerous stamens, frequently bent over to one side. The fruit 

 consists of several carpels, and is sometimes edible. 8orne of the trees
