Chisocheton is a genus of trees in the family Meliaceae.[2] The genus name comes from the Greek schizos and chiton meaning "split tunic", referring to the lobed staminal tube of C. patens. Their range is from India and tropical China, throughout Malesia and south to New South Wales and Vanuatu.[1]

Description

Chisocheton is typically dioecious.[3] Flowers are usually unisexual, rarely bisexual, with a cup-shaped calyx. Fruits are one or two-seeded. Chisocheton habitats are rain forests, typically understorey trees, from sea-level to about 1,500 metres (5,000 ft) altitude.

The wood of several Chisocheton species is used locally in light construction.[1] In the Philippines, the seeds of Chisocheton cumingianus (known locally as balukanag) are used to make a non-drying oil either for traditional medicine or as fuel for oil lamps.[4]
Leaf indeterminacy

Unlike nearly all other seed plants, the leaves of Chisocheton have indeterminate growth - they never stop growing. Instead of forming a terminal leaflet, they form a small leaf-tip bud, which produces new leaflets continuously.[5]

This trait is shared with a few closely related genera, such as Guarea.[6]
