Swartzia
Swartzia is a genus of flowering plants in the family Fabaceae. It was named in honor of Swedish botanist Olof Swartz and contains about 200 species. Swartzia is restricted in its geographical distribution to the New World Tropics, where it occurs primarily in lowland rainforests, but also in savannas, pre-montane forests, and tropical dry forests. While it can be found throughout the wet lowlands from Mexico and the Caribbean islands to southern Brazil and Bolivia, Swartzia is most abundant and species-rich in Amazonia, where 10–20 species may co-occur at a single site. The species of Swartzia are mostly trees, ranging from small understory treelets to large canopy emergents. Some species, especially in savannas, are mult-stemmed shrubs.
Fossil record
Many Swartzia fossils from the middle Eocene epoch are known from the United States. 5 fossil dehiscent seed pods and 50 fossil leaflets have been described from the Warman and Lawrence clay pits in Weakley and the Henry Counties, Tennessee. In addition 6 leaflets have been described from the New Lawrence and Miller clay pits in Henry County, Tennessee.List of species
