Description

edit

Members of this genus are semi-evergreen trees that grow on coastlines. They have compound leaves with usually between 2 and 4 pairs of entire leaflets. The inflorescences are produced from the leaf axils, flowers have a 4-lobed calyx, four petals and eight stamens. The fruit are large, almost spherical capsules that contain up to 20 irregularly shaped seeds. The fruit hangs from the branch on its long peduncle before dehiscing and releasing the seeds.[4][5]

Taxonomy

edit

The genus was erected by the botanist Johann Gerhard König in order to accommodate his newly-described species X. granatum. The name is derived from the Greek words xylon, meaning wood, and carpon, meaning fruit,[4] and is a reference to the large woody fruit. The size and shape of the fruit also give rise the common name "cannonball mangrove".
