Acosmium Explained

Acosmium is a South America genus of flowering plants in the family Fabaceae. Three species are currently recognized.^{[1] [2]} Most Acosmium species have been recently transferred to Leptolobium^[3] and one species to the South American Guianodendron^[4] while the genus Acosmium itself has been transferred from the tribe Sophoreae to the tribe Dalbergieae^[5] in a monophyletic clade informally known as the Pterocarpus clade.
