ELEPHANT TREE- Elephant tree, commonly known as the Bursera

Microphylla, is found in the Anza-Borrego Desert Park region of the United States. It grows mainly on the rocky slopes of desert mountains into a sculptural form with thick water-storing trunk. This tree is native to Mexico, Baja California, Sonora and Zacatecas. They are basically small trees, very short and stout with tapering trunks and branches that resembles the legs and trunks of an elephant and hence got its name. They are semi-succulent with alternate leaves and are mostly once-pinnate or twice-pinnate. The fruit it bears is a drupe and contains a yellow stone. Sceptics refuse to acknowledge the existence of elephant trees until 1937 because of its rare growth and poor distribution.
