Pterocarpus angolensis
Pterocarpus angolensis DC.
Description
Pterocarpus angolensis, commonly known as the African teak, mukwa, or bloodwood, is a deciduous tree belonging to the Fabaceae (legume) family. This species is widely recognized for its high-quality, durable wood and the distinct blood-red sap it exudes when the bark is damaged, which has led to its common name in many indigenous cultures.
Native to Southern and Eastern Africa, the tree is primarily found in open woodlands, savannas, and rocky slopes. Its natural range extends through countries like Angola, Mozambique, Tanzania, and Zimbabwe. The plant has evolved to thrive in environments with distinct wet and dry seasons, making it a robust species within its tropical climate zone.
Botanically, it typically grows up to 15–18 meters in height, exhibiting a spreading, umbrella-shaped canopy. The leaves are pinnately compound, providing dense shade. Flowering occurs during the rainy season, producing vibrant yellow blooms that attract various pollinators. The fruit is a distinctive circular, winged pod that enables efficient wind dispersal of seeds.
Cultivation of this species requires well-drained, deep, loamy or sandy soils. It is intolerant to waterlogging, which often leads to root rot. Successful agroforestry management involves protecting young saplings from fire, as they are sensitive to thermal damage during their establishment phase, and ensuring they receive ample sunlight to promote healthy vertical growth.
- Timber durability: Highly resistant to termites and fungal decay.
- Medicinal value: Bark and sap are used in traditional pharmacopeia.
- Environmental impact: Contributes to nitrogen fixation in poor soils.
- Ornamental potential: Used in urban forestry in frost-free regions.
Economically, Pterocarpus angolensis is highly valued for its timber, which is easy to work with, glues well, and polishes to a high finish, making it a premium choice for high-end furniture and carving. Beyond the timber industry, it plays a vital role in sustainable landscape management, providing soil stability and supporting biodiversity in the savanna ecosystems where it grows.
