Tibouchina is a neotropical flowering plant genus in the family Melastomataceae. Species of this genus are subshrubs, shrubs or small trees and typically have purple flowers. They are native to Mexico, the Caribbean, and South America where they are found as far south as northern Argentina. Members of this genus are known as glory bushes, glory trees or princess flowers. The name Tibouchina is adapted from a Guianan indigenous name for a member of this genus. A systematic study in 2013 showed that as then circumscribed the genus was paraphyletic, and in 2019 the genus was split into a more narrowly circumscribed Tibouchina, two re-established genera Pleroma and Chaetogastra, and a new genus, Andesanthus.
Chaetogastra grossa, synonym Tibouchina grossa, is a species in the Melastomataceae family that is native to Colombia, Ecuador and Venezuela. It is found between 2400 and 3800 meters in elevation. Also called "red princess flower" or "carmine princess flower" to differentiate it from "princess flower" which has purple blooms.
