Ochna integerrima[1] is popularly called yellow Mai flower (Vietnamese: mai vàng, hoàng mai in southern Vietnam, although in the north, Mai usually refers to Prunus mume). In the wild, it is a small tree or shrub species (2-7 m tall) in the genus Ochna (/ˈɒknə/) and family Ochnaceae. The timing of the yellow flowers of this plant make it very popular in southern Vietnam, where (often bonsai-style) plants are purchased during Tết.

In Vietnam, the variety of O. integerrima whose flowers have five petals is called mai vàng (yellow mai), whereas mai núi (mountain mai) flowers have between five and nine petals.

In Cambodia, it is called angkea (អង្គា), angkeasel (អង្គាសីល), angkea loeung អង្គាលឿង or kongkea គង្គា.[2]

Ochna integerrima (Thai: ช้างน้าว Chang nao) is the provincial flower of Mukdahan province, Thailand.[3]
