Synonyms[1][2]
  • Oligocarpha Cass.
  • Synchodendron Bojer ex DC.

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] and Brachylaena huillensis of East Africa is of similar height. 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]
