 They are tetramerous, with an ovary enclosing four uniovulate

have only two branches. The fruit is composed of four cocci, 

 surmounted each by one of the divisions of the calyx. 



A separate tribe (Goussarece) has been made of Coussarea, Faramea,

 differing from Uragoga in only one important character, viz. the little 

 development of the interlocular partition which may be wanting 

 above or disappear altogether. The ovules, also, belonging to the 

 two different cells may even touch each other to a variable extent. 

 In the true Coussarea, they are supported by a very short common 

 erect column. The calyx is gamosepalous, entire, truncate or 

 4-dentate. In those named Faramea, the calyx presents the same 

 variations, or is almost nil ; but the column supporting the ovules
