About Zanthoxylum flavum Vahl
This species, Zanthoxylum flavum Vahl, grows with a straight trunk and forms a limited canopy of pinnately compound leaves. It produces clusters of small pale yellow to cream-colored flowers and small black seeds. Its species epithet 'flavum' is Latin for yellow, and this name refers to the color of its flowers. Pollination of this species is thought to be carried out by bees. Like its close relative Zanthoxylum martinicense, its seeds are believed to be dispersed by birds and bats. In its native subtropical range, Zanthoxylum flavum grows in regions that get average to high rainfall throughout the year, as well as regions that have distinct dry seasons. It can grow on a wide variety of soils with different drainage patterns, including rapidly draining volcanic-derived soils and well-draining clay soils. It can also grow on serpentine soils.
