Fruit and Seed. The ovary is central or excentric, short 

 and two- to ten-lobed, or elongated and one- to ten-celled, with 

 axial or parietal placentation, or the ovules are inserted on the 

 inflexed margins of the carpels. Instances of the short ovary 

 are seen in Gromphia and Ochna, a few of which are grown as 

 stove-plants in this country. The carpels are seated on a large 

 receptacle, round the sides of which they are arranged and 

 connected at the extreme base with the central style. They 

 are so widely separated in the ripe fruit of Ochna that they 

 appear apocarpous. The usual number of ovules in each cell 

 is one or two, sometimes many ; they are ascending and ana- 

 tropous, with an inferior micropyle and ventral raphe, rarely 

 pendulous with a superior micropyle. A one-celled ovary with 

 three parietal placentas occurs in Wallacea. 



The fruit consists of three to ten drupes arranged in a 

 whorl, as in Ochnese, with one ovule in each cell, and exal- 

 buminous seeds. In Euthemis it consists of five portions 

 having a woody endocarp, and albuminous seeds. It is capsular 

 in the tribe Luxemburgieae with albuminous seeds. Where 

 present the endosperm is fleshy. The testa is membranous in 

 most cases, but is winged in Luxemburgia, thick in Wallacea, 

 and produced into a linear sheath in Cespedesia. 



The embryo is generally straight and terete, but there are 

 exceptions, especially amongst the exalbuminous seeds. The
