The fruit, with two or three cells, is cap- sular and dehiscent, or indehiscent and sometimes even completely fleshy. Fig 240.

The fruit, more often indehiscent than dehiscent, has from one to three cells ; but it is easily distinguished by a character otherwise of little importance in itself: it has the anther cells in a wallet, at first pendant, then erect after anthesis. Antidesma has been observed in all warm regions of the globe. Beside this and Securinega are also placed: Jporosa, which, under the name of Scepa^ was also considered to constitute a separate order, having the male flowers arranged in cat- kins, with anthers whose cells are longitudinally adnate. The an- droceum, inserted round a central body, often small or even wanting, is usually formed of two divi- sions, like the gyneeceum: the fruit is capsular. It inhabits the tropical regions of Asia and Oceania. Cometia, formed of shrubs from Madagascar (which ought perhaps to be included in the preceding genus), has also catkins with 3-5-androus flowers, and a uni-carpellary gyneeceum; the fruit is fleshy.
