Identification

The Malinche is easy to recognize by its wide, umbrella-shaped canopy and spectacular scarlet-red flowers. Its delicate, fern-like leaves consist of hundreds of tiny leaflets, giving the tree a soft, feathery appearance.

During the dry season, the tree often loses most of its leaves before flowering, allowing the brilliant blossoms to completely cover the crown.
