Eugenia

Belongs within: Myrteae.

Eugenia is a genus of trees and shrubs that can be distinguished from closely related taxa by its pinnately veined leaves, single-seeded fruit and massive cotyledons (Flora of China). The centre of diversity for the genus is in the Americas but species are found throughout the tropics. The fruit of some species, such as the water apple or jambu air Eugenia aquea, is edible. The aromatic flower buds of clove E. aromatica, a native of the Maluku Islands in Indonesia, are widely used for flavouring food.

Characters (from Flora of China): Trees or shrubs. Leaves opposite, petiolate; leaf blade pinnately veined. Inflorescences axillary or often lateral below leaves. Flowers bisexual, solitary or clustered. Hypanthium short. Calyx lobes 4. Petals 4. Stamens numerous; anthers parallel, longitudinally dehiscent. Ovary 2- or 3-loculed; ovules many per locule, amphitropous. Fruit a berry, with persistent sepals at apex. Seed usually 1, embryo straight, with 2 fully or partly fused massive cotyledons.
