An Order widely distributed over both the New and the Old World within the tropics, 

 and not spreading far beyond them either northward or southward. Of the five Austrahan 

 genera, three are dispersed over the greater part of the area of the Order, the two other 

 small ones are, as far as known, endemic.

Cal}^-segment3j corolla-lobes, stamens and cells of the ovary 5 each or 

 rarely in species not Australian 6 to 8 each. No staminodia, nor any scales 

 to the corolla. Seeds usually one or few ; testa hard and smooth ; hilum lateral 

 reaching at least halfway up ; albumen scanty or none ; cotyledons thick and 

 fleshy. — ^Trees or shrubs. Leaves usually rusty or silvery-tomentose under-

The genus is chiefly tropical- American, with a few African and Asiatic species. The on J 

 Australian one is endemic, and very different from any other in several respects.
