Bertero's simarouba (Simarouba berteroana)
Simarouba berteroana: Native Tree of Hispaniola
Populating the tropical dry forests of Hispaniola, Simarouba berteroana grows as a medium-sized woody tree. It plays an important role in the local forest canopy and ecosystem stability of the Caribbean region.
The species was formally documented by botanists Leopold Krug and Ignatz Urban. It thrives primarily in the karst and limestone regions of both Haiti and the Dominican Republic.

Morphology
The plant exhibits an upright growth habit with a smooth, greyish-brown bark. The leaves are pinnately compound, consisting of multiple pairs of oblong-elliptic leaflets with a slightly leathery texture.
Small, greenish-yellow flowers are produced in dense terminal panicles. The species is dioecious, meaning male and female flowers are borne on separate individuals to ensure cross-pollination.
Following successful pollination, the female trees produce oval drupes. These fruits turn orange or dark purple when fully ripe, attracting local avian species.
Applications
The bitter bark and roots are historically used in traditional herbal preparations. Local communities employ extracts to address digestive issues and reduce fevers.
The timber, although light, is used for regional building purposes, fence posts, and charcoal production. It is valued for its ease of processing in rural carpentry.
Interesting facts
- This species is highly adapted to the seasonal dry seasons and limestone soils of the Caribbean islands.
- Its bitter compounds, like those of its congeners, serve as a natural defense mechanism against herbivorous insects.
