RUBIACEJE. 311 



two hundred species ^ belonging to all warm regions of the 

 globe. 



Amaioua is extremely near Genipa, The flowers are dioecious, 

 generally hexamerous. The calyx is gamosepalous, entire or with 

 six teeth, sometimes long and narrow, and the corolla is contorted, 

 coriaceous, with pointed straight or curved bud. The ovary has 

 two complete or incomplete multiovulate cells, and the fusiform 

 style is divided or not into two branches. The fruit is a many- 

 seeded berry. They are trees or shrubs from tropical America, with 

 terminal or subterminal flowers in corymbiform cymes. The female 

 flowers are less numerous or even solitary in the inflorescences. 

 Duroia is Amaioua whose flowers have a developed calyx and the 

 throat of the corolla destitute of hairs or nearly so. The number of 

 cells, complete or incomplete, in the ovary varies from two to four. 

 In Alibertia, which can only form a section of the genus Amaioua, 

 the number of parts in the flower varies from four to eight and the 

 ovarian cells, generally incomplete, vary from two to eight. Gordiera 

 is also of the same genus and from the same country ; but the 

 contorted corolla with pointed lobes, presents in the bud an enlarge- 

 ment corresponding to the limb, and another, as slightly marked, 

 corresponding to the base of the tube.^
