Swietenia
Swietenia is a genus of trees. They are medium-sized to large trees growing to 20 to 45 m tall, and up to 2 m trunk diameter. The leaves are pinnate, with 3-6 pairs of leaflets, the terminal leaflet absent. The leaves are deciduous to semi-evergreen. The flowers are produced in loose inflorescences, each flower small, with five white to greenish-yellowish petals. The fruit is a pear-shaped five-valved capsule, containing numerous winged seeds. It is usually taken to consist of three species, geographically separated. It occurs natively in the Neotropics, from southern Florida, the Caribbean, Mexico and Central America south to Bolivia.
