About

Tabernaemontana donnell-smithii is an evergreen tree in the dogbane family Apocynaceae commonly known as the horse balls tree. In Spanish, it is huevos de caballo, cojones de burro, cojón de mico, or cojotón. The name huevos de caballo comes from the oval shape of the tree's hanging fruit. It is native to Mexico and Central America. The type locality is San Felipe, Retalhuleu in Guatemala. Tabernaemontana donnell-smithii is similar to Tabernaemontana glabra, except that its leaves and flowers are smaller and its fruit is larger.

Tabernaemontana donnell-smithii lives in a variety of habitats, including various types of forest, the forest edge, and pastures. It grows up to 20 metres (66 ft) tall, although the height is partially dependent on the habitat. Trees living in secondary growth areas, forest edges and pastures are generally shorter but broader than those in forests.
