Pachira quinata

About

Pachira quinata, commonly known as pochote, is a species of flowering tree in the mallow family, Malvaceae. It inhabits dry forests in Costa Rica, Nicaragua, Honduras Panama, Venezuela, and Colombia. Pochotes bear large, stubby thorns on their trunk and branches and are often planted as living fenceposts with barbed wire strung between them. These thorns are also often used to make small house-like sculptures that are believed to bring protection to someone's house since the pochote is believed to be sacred.
