Description

[edit]

Entandrophragma is restricted to tropical Africa.[2][3] At least some of the species attain large sizes, reaching 40–50 m tall, exceptionally 60 m, and 2 m in trunk diameter. In 2016 a specimen ofEntandrophragma excelsum towering at a height of 81.5 m (267 ft 5 in) tall, and a 2.55 m (8 ft 4 in)dbh[4] was identified atKilimanjaro.[5]

It isdioecious, with male and female flowers on separate plants.[6] Theleaves are pinnate, with 5-9 pairs of leaflets, each leaflet 8–10 cm long with an acuminate tip. Theflowers are produced in looseinflorescences, each flower small, with five yellowishpetals about 2 mm long, and tenstamens. Thefruit is a five-valvedcapsule containing numerous wingedseeds.

It is sometimes termed under the generic label ofmahogany, and whileEntandrophragma is part of the family Meliaceae, it is not classified asgenuine mahogany. The species shares many of the characteristics of genuine mahogany and is used as an alternative, withSapele andUtile in particular bearing a close resemblance.[7][8]
