Eusideroxylon is a genus of evergreen trees of the family Lauraceae. The genus is monotypic, and includes one accepted species, Eusideroxylon zwageri. It is known colloquially in English as Bornean ironwood,[3] billian, or ulin.[3]
It is native to Borneo and Sumatra,[2] where it grows in lowland rain forests.[1]
Eusideroxylon are hardwood trees reaching up to 50 metres in height with trunks over 2 metres (6 ft 7 in) in diameter, producing commercially valuable timber.[citation needed] The wood of E. zwageri is impervious to termites, and can last up to 100 years after being cut.[citation needed] Due to extensive logging, it is listed as vulnerable in the IUCN Red List.[1]
