nivent, valvate in aestivation ; inner petals, when present, valvate or imbricate 

 towards their apices. Stamens indefinite, the connective more or less 

 thickened beyond the anther-cells, ovate or truncate. Torus hemispherical 

 or conical. Carpels indefinite. Ovaries connate or immersed. Styles and 

 oblong stigmas free. Ovules solitary, erect. Fruit globose ovoid or cor- 

 date, multilocular, consisting of the mature one-seeded carpels imbedded

 cicled or rarely cymosely racemose, terminal or extra-axillary. 



A large genus of which by far the larger number of species (about 50) are tropical 

 American. One American species (A. palustris) appears to be truly native also in swamps 

 of West Tropical Africa, and four other species of the New World, which are widely cul- 

 tivated for the sake of their excellent fruit, often become naturalized. There are no species 

 indigenous in continental Asia. A few very distinct species occur in Madagascar and 

 Mauritius.
