Trees or shrubs, mostly with a milky juice, simple and entire alternate 

 leaves (often rusty-downy beneath), small and perfect regular flowers usually 

 in axillary clusters; the calyx free and persistent ; the fertile stamens com-

 them, inserted on its tube, along with one or more rows of appendages and 

 scales, or sterile stamens ; anthers turned outwards ; ovary 4 - 12-celled, with 

 a single anatropous ovule in each cell; seeds large. Albumen mostly none ; 

 but the large embryo with thickened cotyledons. Style single, pointed. 

 A small, mostly tropical order, producing the Sappodilla or Star-apple, and 

 some other edible fruits, represented in our district only by the genus
