Cassine orientalis, known locally as bois d'olive, is a tall canopy tree endemic to the Mascarene islands of Mauritius, Reunion and Rodrigues.

In its native islands the tree has been severely over-exploited for its valuable reddish wood.

Adults reach up to 20 meters in height.

The fruits resemble small olives, from which the local name derives.

[1] Juveniles have shiny narrow leaves with a bright red mid-rib and smooth edges; while adult leave are wide and oval with a serrated margin.
