Melanorrhoea usitata

Melanorrhoea usitata (also known as Burmese lacquer,[1] theetsee,[2] thitsi[3] or ringas[4]) is a tree of the Anacardiaceae family.

It is a medium to large deciduous tree from the dry deciduous forest with a straight clean cylindrical bole and a spreading crown of dark green leaves.[3]

This species is used in Burma and northern Thailand as a source of lacquer used for producing varnish, waterproof or preservative paint, glue, ceramic and lacquerware.[2][3] Timber (known as Borneo rosewood[4][5]) is used for furniture and inlay work.[2]

Both tree's sap and sawdust can cause dermatitis and skin irritation.[2]

It is an endangered species.[6]

Synonyms include: Gluta usitata Ding Hou.[2]

An incompletely identified 4-heptadec(en)yl catechol, which was named thitsiol, has been reported to occur in this species.[2] Sap also contains urushiol.[7]
