1. Uvaria L. — Flowers hermaphrodite more rarely polygamous 

 or dicBcious ; receptacle convex, more or less elongated. Sepals 3, 

 free or connate to a variable height, usually valvate. Petals G, free 

 or connate at the base, equal or unequal, 2-seriate, imbricated ; 

 sometimes the inner or outer set finally valvate. Stamens oc, linear 

 or flattened ; connective dilated above the linear extrorse longi- 

 tudinally dehiscing cells, truncate or ovate, more rarely subfoliaceous. 

 Carpels oo, more rarely few, grooved internally ; style continuous 

 truncate, apex stigmatiferous entire or 2-fid ; ovules cc, more rarely 1, 

 2, ventral, in two rows, horizontal or subascending ; micropyle lateral 

 or extrorse and inferior. Berries of variable form, entire or more or
