celled, with 1 ovule in each cell, erect penJulous or laterally attached. Style 

 simple, with an entire or very slightly lobed stigma. Fruit a berry or . drupe,

An Order widely distributed over both the New and the Old World within the tropics, and not 

 spreading far beyond them either northward or soathward. Of the 5 Australiiin genera, three 

 are dispersed over the greater part of the area of the Order, the two other sriiall ones are, as far 

 as known, endemic. — Benth.
