General Information

Coutarea hexandra is a semideciduous plant. It can vary in habit from a shrub, that can often produce stems that scramble into the surrounding vegetation, to a more tree-like form with a very dense, globose crown. The tree-form can grow 4 - 6 metres tall and has a short, usually crooked bole 15 - 25cm in diameter[, ]. In some areas, such as Costa Rica, specimens up to 18 metres tall have occasionally been recorded[].
The plant is much used as a substitute for quinine when treating malaria. It is commonly harvested from the wild for this purpose and also for its wood. An ornamental plant, its small size makes it suitable for planting in narrow streets and under power lines[].
The plant has a very wide range but, in areas such as Brazil, the population has been drastically reduced because the plants have been cut down for their medicinal uses[].
