Safety Overview
1.Voacanga — Overview
Voacanga africana, commonly known as Voacanga, is a captivating perennial shrub or small tree belonging to the Apocynaceae family, typically reaching heights of up to 6 meters. Its bark is distinctively smooth, pale grayish-brown, and often features a subtle waxy texture. The plant’s leaves are arranged oppositely, exhibiting an ovate to elliptical shape with a glossy dark green upper surface and a paler underside, growing up to 30 cm in length. Their margins are smooth, and a fine vein reticulation is visible beneath.
Voacanga produces striking tubular, star-shaped flowers, which are usually yellow to pale green and measure approximately 3-5 cm, blooming primarily between March and June. These blossoms give rise to paired, follicular fruits that are spherical, mottled green, and contain numerous flat, oblong seeds embedded within a pulpy, yellow mesocarp. Native to tropical West Africa, Voacanga africana thrives in the understory of tropical rainforests and in secondary growth forests, preferring areas with rich, moist, and well-draining soils. Taxonomically, it is classified under the genus Voacanga, within the alkaloid-rich Apocynaceae family.
A notable characteristic is its milky latex sap, which is present throughout the plant and indicative of its potent chemical composition. This species is sometimes confused with other members of its family due to shared morphological traits.
