Smooth climbing shrubs with short supra-axillary often arrested and 

 circinately booked branches. Leaves usually in terminal tufts, coriaceous, 

 entire, reticulately feather-veined ; stipules small, caducous or incon- 

 spicuous. Flowers usually small, very caducous, in terminal or lateral 

 panicles. Galyx-tvbe at first very short, adnate to the base of the ovary 

 with imbricate lobes, finally turbinate and adnate to the fruit with the lobes 

 unequally enlarged, spreading and membranous. Stamens 5 or 10, subpe- 

 rigynous. Ovary 1-celled, inferior ; styles 3, articulated to a rounded or 

 shortly cylindrical epigynous disk ; ovule solitary, erect or laterally a£5xed. 

 Seed subglobose, testa prolonged into the ruminations of the copious fleshy 

 albumen ; embryo ^hort, straight ; cotyledons short, divergent. — Distkib.
