Identification
Morphology
Curtisia dentata is a self-supporting plant that establishes itself through a distinct tree growth form. This species is characterized by its impressive stature, typically reaching a maximum height of 20 meters. While it can exist as a smaller specimen with a minimum height of only 2 meters, it often matures into a much more substantial presence. In most environments, the tree tends to stabilize within a range that starts at a minimum of 15 meters. Such versatile growth allows it to occupy various niches within its natural habitat.
