Distribution
A genus of three species, two of which are African, the other originally from India and Malesia (including New Guinea), but now cultivated and naturalised throughout the tropics - Melia azedarach L.
Morphology General Habit
Trees and shrubs to 40 m tall
Morphology General Indumentum
Indumentum of simple and stellate hairs
Morphology Leaves
Leaves bipinnate, margins entire or serrate, 1 pair of glands at the base of the petiole
Morphology Reproductive morphology Inflorescences
Inflorescences axillary, occasionally on short shoots, thyrsoid, many-branched
Morphology Reproductive morphology Flowers
Flowers bisexual or male and plants polygamous, 5(–6)-merous; sepals deeply lobed, imbricate; petals free, imbricate; staminal tube narrowly cylindrical, slightly expanded at apex, ribbed along length and lobed at apex, lobes sometimes bifid or 4-fid, anthers inserted at margin of tube, alternating with lobes; disk annular, surrounding ovary; ovary 4–8-locular, 2 ovules per locule, style capitate or tipped with 4–8 erect or incurved lobes
Morphology Reproductive morphology Fruits
Fruit drupaceous, pericarp fleshy, endocarp thick, bony
Morphology Reproductive morphology Seeds
Seeds usually 1 per locule, oblong, flattened.
Ecology
Melia in New Guinea are forest trees, usually found in seasonally dry forests and savannahs where it is often associated with Eucalyptus, former gardens and secondary forest, up to 1200 m.
Recognition
Melia can be distinguished by the bipinnate leaves, presence of stellate hairs, the capitate or many-lobed top of style and the drupaceous fruit. In Melia there is a single pair of circular glands at the base of the petiole, cf. Azadirachta where there is an additional pair of linear glands below these.
