Brachylaena is a genus of flowering plants in the aster family, Asteraceae. Several are endemic to Madagascar, and the others are distributed in mainland Africa, especially the southern regions.[3]
These are trees and shrubs with alternately arranged leaves. One of these, Brachylaena merana, is the tallest of all composites ('daisy trees") at up to 132 feet (forty meters).[4] They are dioecious, with male and female flowers occurring on separate individuals. The flower heads are somewhat disc-shaped. Heads with female flowers are larger and produce larger pappi.[5]
B. huillensis is the only widespread species,[3] growing as a dominant tree in Brachylaena woodlands and a common species in some eastern African forests. It provides critical habitat for many animal species. It is also sought after for its wood and has been overexploited.[6]
Some species are subject of dispute:
