Byrsonima is one of about 75 genera in the Malpighiaceae, a family of flowering plants in the order Malpighiales. In particular in American English, they are known as locustberries (which also may refer specifically to Byrsonima coccolobifolia or Byrsonima lucida). Another widely seen common name is serrets or serrettes. Byrsonima comprises over 135 species of trees, shrubs, and subshrubs found in the New World tropics and subtropics from southern Mexico, southeastern Florida, and the Caribbean to southeastern Brazil. The plants have entire leaves, yellow flowers, and fleshy, edible fruits called nance; B. crassifolia in particular is known by that name, as it is an underutilized crop of some commercial importance in Latin America. They are primarily pollinated by various oligolectic native bees (e.g., Centris, Epicharis, and Tetrapedia) that are specialized to collect floral oils, as the flowers do not offer the typical floral rewards.
