Funtumia elastica

Funtumia elastica is a notable evergreen tree species belonging to the Apocynaceae family. Often referred to as the Lagos rubber tree or silk rubber, it serves as a significant biological source of latex. The tree is characterized by its tall, slender habit, reaching significant heights in the lush tropical environments of its native range.

Originating from the tropical regions of West and Central Africa, this species thrives in evergreen forests. Its natural distribution spans across countries like Nigeria, Cameroon, and the Democratic Republic of the Congo. It has historically been utilized in plantation agriculture, where it was introduced to supplement the global demand for natural rubber production.

Botanically, the tree exhibits glossy, leathery leaves arranged in opposite pairs along the branches. Its flowers are creamy-white, fragrant, and attract various pollinators. The fruit develops as woody pods containing seeds with silk-like appendages, which aid in wind dispersal, ensuring the species can regenerate effectively in dense forest understories.

Agricultural requirements include a consistent high-humidity climate and well-drained, nutrient-rich soil. For successful cultivation, growers must ensure proper space between trees to minimize competition for sunlight. While it is more resistant to certain pests than other rubber-yielding trees, young plantations must be protected from weeds and intense direct solar radiation during the establishment phase.

Economically, Funtumia elastica is valued for its latex, which is harvested from the bark. Although its yield per tree may be lower compared to Hevea brasiliensis, it remains an important forest resource. Furthermore, its light-colored, moderately soft wood is utilized in carpentry and the manufacturing of simple household articles, making it a dual-purpose agricultural and forestry product.
