Geographical Distributions

Toona sureni is found in Nepal, India, Bhutan, Burma (Myanmar), Indo-China, southern China, Thailand and throughout Malesia to western New Guinea.


Toona sureni is a medium-sized to fairly large tree which is up to 40(-60) m tall, with a branchless bole up to 25 m long, measuring up to 100 cm in diametre and even up to 300 cm in the mountainous areas. The buttresses, if present, are up to 2 m high. The surface of the bark is usually fissured and flaky. It is whitish, greyish-brown or pale brown and with aromatic odor when cut.

The leaflets are entire and usually hairy on veins. The ovary and disk are hairy.

The columella of fruit is concave with apical scarring, with rough fruit valves and warty with conspicuous lenticels. The seed is winged at both ends.

Ecology / Cultivation

Toona sureni occurs in primary forests but is more common in secondary forests, often on riparian hillsides and slopes, up to 1700(-2100) m altitude. Locally in Papua New Guinea, it can make up to 6% of the gross volume of the natural forest. In Sulawesi, a large-fruited geographical variant is found, described as Cedrela celebica Koord.; perhaps this is a distinct geographical taxon. The density of the wood is 270-670 kg/m3 at 15% moisture content.
