Distribution Overview
reported to grow from southern Colombia and Venezuela to the Guianas, and south through most of non-coastal Brazil to Bolivia. It is usually found from sea level to elevations of about 5570 feet (1700 m). The trees are often locally common in poorly drained swampy areas where it mostly occurs, and sometimes forms nearly pure stands.
