Dacryodes edulis, commonly referred to as African Pear or Safou, is a tropical tree that belongs to the Burseraceae family. This evergreen tree is highly valued for its edible fruit, which holds both culinary and medicinal significance.
Dacryodes edulis is a medium to large-sized tree that can reach heights of up to 20 meters (65 feet). The tree possesses a well-defined, symmetrical canopy with dense foliage. Its evergreen leaves are alternate and pinnately compound, consisting of several glossy, elliptical leaflets that vary in size, ranging from 5 to 15 centimeters in length.
The bark of Dacryodes edulis is typically gray or brown and exhibits a relatively smooth texture on young trees. As the tree matures, the bark may become more fissured and roughened. The trunk of the tree is sturdy and straight, branching out into a dense crown of leaves and eventually producing clusters of fruit.
Dacryodes edulis produces small, inconspicuous flowers that are borne in panicles or clusters. These flowers are usually yellowish-green in color and lack showy petals. The inflorescences can emerge directly from the trunk and larger branches, creating a unique visual display.
The fruit of Dacryodes edulis is the highlight of the tree. It is a drupe or stone fruit that resembles a pear in shape, hence the common name African Pear. The fruit’s skin can range in color from green to purple, and its texture is smooth or slightly rough. The flesh of the fruit is rich, creamy, and oily, with a flavor that varies from sweet to savory. The fruit contains a large seed in the center.
Dacryodes edulis is native to Central and West Africa, thriving in tropical rainforests and subtropical regions. It prefers well-drained soils and is often found near rivers and streams. The tree’s ability to adapt to a range of environments has led to its cultivation in various countries within its native range.
Cultivation of Dacryodes edulis is primarily for its fruit, which holds cultural, economic, and nutritional importance in many African communities. The fruit can be eaten fresh, cooked, or processed into oils and jams. Additionally, the tree’s wood is occasionally used for construction and carpentry.
Due to the tree’s significance as a food source and its traditional importance, Dacryodes edulis is cultivated and managed in agroforestry systems. However, like many tree species in tropical regions, it may face threats from deforestation and habitat loss.
