 hypogynous, or adherent to the base of the petals, or arranged in groups of 

 3 before the petals, filaments subulate, glabrous ; anthers minute, didymoas, 

 opening longitudinally. Staminodes 0. Disk liyp.ogynous, fleshy, very

 peninsula and Borneo. In technical characters allied to Ximenia, but dif- 

 fering in habit, arrangement of the leaves, inflorescence and number of
