Buchanania


Buchanania is a genus of plants in the mango and cashew family Anacardiaceae, native to areas from India to southern China, and southwards to northern Australia and the western Pacific.

Description

This genus consists of trees with, unlobed leaves arranged alternately on the twigs. Flowers are produced in or terminal panicles. Flowers are bisexual, i.e. they have both male and female organs. They usually have 5 lobes and 5 petals, sometimes 4 or 6, and are pale green to white. There are 10 stamens and 4–6 carpels, only one of which is fertile. Fruits are more or less lens-shaped drupes with a bony or woody, and contain a single seed. Unlike other genera in the family, Buchanania does not appear to cause contact dermatitis.

Taxonomy

The genus Buchanania was erected in 1801 by German botanist Kurt Polycarp Joachim Sprengel based on a collection of plant material by Francis Buchanan-Hamilton from what is now Myanmar. The genus was named after the collector.
