Swietenia mahagoni

Swietenia mahagoni
Biggest Plant Dictionary | Swietenia mahagoni | Swietenia mahagoni is a tall tree, up to 30 m high, with a short, buttressing base, up to 1 m in diameter and a large, spherical crown, many heavy branches and dense shade. The bark is smooth grey on young trees, turning to scaly dark reddish-brown on large trees.
The tree is deciduous in areas where it is subject to drought. Leaves even, pinnate, 10-18 cm long, and bearing 4-10 pairs of leaflets that are shiny, dark green, lance-shaped, 2.5-5 cm long by 0.7-2 cm broad. Flowers greenish-yellow, 6-8 mm across, in axillary panicles; panicles glabrous, shorter than the leaves. The light brown seed capsule stands upright, about 6-10 cm long by 4-5 cm diameter, with 5 valves splitting upward from the base. Each valve releases about 20 flat, brown, winged seeds, 4-6 cm long. Swietenia commemorates Gerard von Swieten (1700-1772), botanist and physician to Maria Theresa of Austria.
