Byrsonima lucida: Food and Medicine

Byrsonima lucida

The Locusberry rises to the occasion.  When the soil is poor it is a foot-high tree. When the soil is good, it can be ten feet high. And much father south, it’s a grown up tree.

The variability of the Locusberry, Byrsonima lucida (bur-SO-nim-uh LOO-sid-uh) doesn’t stop there.  When it first flowers, the blossoms are are white. Then they turn to pink and then to crimson. This is an interesting strategy: The different colors attract different butterflies to assure pollination. Also the oil glans on the underside of the petals change color from green to yellow.  Bees visit the blossoms, but not to pollinate per se. They take oil from the glands to make their nests. The fruit turns from green to red-brown, or brown-red,  and persists on the tree. Some think they taste like cranberries, others think they taste soapy.

There are over 135 different Byrsonima from southern Mexico to southeastern Florida, the Caribbean down to Brazil. B. crassifolia (krass-ih-FOH-lee-uh) is considered the best.  The fleshy fruits are called nance and are an underutilized crop in Latin America. In Brazil they are called muruci. The fruits are also important to wildlife including the Golden Conure, moth-butterflies, the Tehuantepec Jackrabbit, an endangered species, and the Florida Box Turtle which thinks the seeds are just great and does its best to spread them around. Byrsonima is from two Greek words, Byrsa meaning hide, and nema, meaning thread. It is a reference to the bark of some of the species. Lucida means bright. clear, lustrous, crassifolia, thick leaves. The bark is often used as a dye which appears to also be antibacterial. .
