Characteristics

They are evergreen hermaphrodite trees or rarely shrubs with leathery leaves of lauroide type. The flowers are in panicles axillary or subterminal, lax. The flowers are bisexual and small, with obconica floral tube, cylindrical or campanulate, six tepals equals, the tube and the base of the tepals hairy inside; fertile stamens 9, 6 or 3, anthers bivalve stamens of I and II whorls eglandular, anthers introrsas, the glands of the third whorl with basal extrorse anthers, those of the fourth whorl staminodes, triangular or ovoid ovary globose, glabrous, included in the floral tube, cylindrical style, stigma discoid. The berry is an ellipsoid dome with basal woody pedicels continuous with the capsule thickened. The berry have a single seed dispersed mostly by birds.

Ecology

They Grow in low evergreen tropical forest in Amazon region but also in tropical mountain cloud forest. Species in less humid environment are smaller or less robust, with less abundant and thinner foliage and have oleifera cells that give trees a more fragrant aroma.

The laurel trees falls within the broad-leaved forests; mid-montane deciduous forests; and high-montane mixed stunted forests. Some species growing to high altitude forests at 1500–3300 m (4,921.3–10,826.8 ). The upper limit of forests ranges from 3000 metre.
