NAT ORAL HISTORY OF PLANTS. 



lobes (fig. 372-374). The two lateral cells and the corresponding 

 stylary branches may be wanting. In the internal angle of each 

 cell is an axile placenta supporting a single ascending incompletely 

 anatropons ovule, with micropyle inferior and exterior. The fruit 

 is a berry. The seeds, surrounded by a fleshy pulp,^ enclose under 

 their coats a large fleshy and undivided embryo. 



In the true Oarcinia "■ the flowers are generally tetramerous (fig. 

 354, 376-378). The sepals are imbricate-decussate and the two 

 exterior are not unfrequently ' much smaller than the others. The 

 stamens are generally arranged like those of Xanthochymus, either 

 free or united in five fascicles or sometimes more, with anthers 



Gurcinia Mnngoiytana.

fertile only in the male or hermaphrodite flowers. The organization 

 and mode of dehiscence of these anthers are very variable. In Q. 

 Mangostana and analogous species,"' they are bilocular. In the 

 ■species of the Cambogia series, they have two cells or four cellules, 

 equally dehiscing by clefts. In 0. Morella^ (fig. 354, 378), they 

 are peltate and open by a sort of small lid like a pyxis. ^ The 

 gynsecium is composed of a very variable number of carpels (from 

 two to a dozen). The ovary encloses, in the internal angle of each 



'', Seminal coats transformed.
