A tropical tree genus in the legume family known for its hard, red seeds that were historically used as a unit of weight in jewelry.
From Greek 'aden' (gland) + 'anthera' (anther, the pollen-producing part of a flower). The name refers to the gland-like structures on the flower's anthers.
These seeds were so uniform and reliable that they became the basis for carat weights in gemstones—a single seed equaled one carat, and that standard persists in jewelry today!
