Sand calunga (Simaba arenaria)
Simaba arenaria: Coastal Sandy Soil Plant of Bahia and Sergipe
Thriving along the sandy coastal dunes of northeastern Brazil, Simaba arenaria is adapted to the harsh conditions of the restinga vegetation.
This species, formally described by botanists Devecchi and Pirani, is primarily found in the states of Bahia and Sergipe. Its ability to tolerate salt spray, high solar radiation, and nutrient-poor sandy soils makes it a key stabilizing plant in its native habitat.

Morphology
The habit of Simaba arenaria is typically shrubby, reflecting its wind-swept coastal environment. It features sclerophyllous leaves that reduce water loss, and small, compact flowers designed to withstand coastal breezes.
Its root system is extensive, anchoring the plant firmly in shifting sand dunes while tapping into deep freshwater tables.
Applications
No direct agricultural or commercial applications are recorded for Simaba arenaria. Its primary value lies in ecological restoration, helping to prevent coastal erosion and preserve the fragile restinga sand dunes.
Interesting facts
The specific epithet arenaria is derived from the Latin word for sand, directly pointing to its preferred habitat.
- It is one of the few species in the Simaroubaceae family specifically adapted to saline sand dune environments.
- The botanists who described this species, Devecchi and Pirani, are leading authorities on the family Simaroubaceae in South America.
