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]
