Khaya is a genus of seven species of trees in the mahogany family Meliaceae, native to tropical Africa and Madagascar. All species become big trees 30–35 m tall, rarely 45 m, with a trunk over 1 m trunk diameter, often buttressed at the base. The leaves are pinnate, with 4-6 pairs of leaflets, the terminal leaflet absent; each leaflet is 10–15 cm long abruptly rounded toward the apex but often with an acuminate tip. The leaves can be either deciduous or evergreen depending on the species. The flowers are produced in loose inflorescences, each flower small, with four or five yellowish petals and ten stamens. The fruit is a globose four or five-valved capsule 5–8 cm diameter, containing numerous winged seeds.
