The tree is characterized by its thick, leathery leaves that are dark green and glossy, providing a striking appearance in its natural habitat. The lancewood has a unique growth pattern, with juvenile plants displaying long, narrow leaves that change to broader, more rounded leaves as they mature. This species plays a role in the ecosystem by providing habitat and food for various wildlife, including birds and insects.
