Morphology
This typical variety is characterized by its completely glabrous (hairless) leaves and stems. The leaflets are alternate, shiny green above, and paler underneath. The mature tree can reach heights of up to 35 meters in optimal rainforest conditions.
Its flowers are small, yellow-green, and produce a nectar that attracts diverse insect pollinators. The smooth, drupaceous fruits are highly sought after by local wildlife. These seeds germinate rapidly once they reach moist soil.
Applications
The timber, known commercially as marupΓ‘, is highly sought after for its uniform texture and easy drying process. It is widely used in interior joinery, plywood production, and model making. The species is also planted in reforestation projects due to its fast growth rate.
Medicinally, the bark has a long history of use against digestive ailments. It was historically exported to Europe under the name dysentery bark to treat outbreaks of the disease.
Interesting facts
The botanical term typica indicates that this is the variety upon which the species description was originally based. The seeds contain a high concentration of edible oil that has been used locally for soap making. Despite its bitterness, the tree is a favorite nesting site for several tropical bird species.
