Small trees or shrubs. Flowers solitary or fascicled, terminal or leaf- 
opposed. Sepals 3, small, valvate. Petals 3 or 6, valvate in 2 series or 
the inner series wanting, the outer ones 3-angled or broad and flat, concave 
at the base, the inner ones quite different from the outer. Stamens 
numerous; anther-cells narrow, dorsal, contiguous, top of the connective 
ovoid. Ovaries many, subconnate; style oblong; ovule 1, erect. Ripe 
carpels confluent into a many-celled, ovoid or globose, many-seeded, fleshy 
fruit. (Said to be derived from the Malay name menona.) 
Species many in Africa and America, several other species introduced 
from the latter region into other tropical countries for the sake of their 
edible fruits; 3 species in the Philippines, all introduced from Mexico at 
an early date.
