Inga marginata

Inga marginata, commonly known as ingá-feijão or river ingá, is an evergreen tree in the family Fabaceae native to South America, ranging from Bolivia and Brazil to Paraguay and northern Argentina, where it is a common component of riparian and Atlantic Forest vegetation. The tree typically grows 5 to 15 metres tall with a spreading crown and a short, often crooked trunk clad in greyish, finely fissured bark. The leaves are alternate and paripinnate with two pairs of opposite leaflets, the upper pair larger and the rachis bearing a small interfoliolar gland between each pair of leaflets and a conspicuous narrow lateral wing or margin that gives the species its epithet. Leaflets are oblong-elliptic to lanceolate, 4 to 10 centimetres long, glabrous to sparsely pubescent. Inflorescences are short axillary spikes of small, fragrant whitish flowers with very long projecting stamens forming brush-like clusters. The fruits are flattened, slightly curved indehiscent pods 5 to 12 centimetres long containing several seeds enveloped in a sweet edible white sarcotesta.
