Coalwood

Lachnostylis hirta, the coalwood, is a small to medium-sized deciduous tree in the family Phyllanthaceae native to the woodlands, bushveld, and savanna regions of southern Africa, occurring across Zimbabwe, Mozambique, South Africa, and into Botswana. The species typically reaches 3–8 meters in height and is recognized by its hairy or pubescent young stems and leaves, a characteristic reflected in the specific epithet hirta, meaning hairy or rough. Coalwood grows on a variety of soil types from sandy soils in lowveld thornveld to clay soils in mixed bushveld, tolerating moderately dry conditions and seasonal drought. Its dense, hard timber has a dark color when charred, which may account for the common name coalwood, and has historically been used for fuel and in traditional construction. Small white flowers are produced in clustered axillary inflorescences and are followed by small, three-lobed capsular fruits. The species is classified as Least Concern by the IUCN, being relatively common and widespread across its southern African range. It contributes to the woodland ecosystem as a browse plant for various herbivores and provides cover for small mammals and birds within the dense woodland understorey of the region.
