Triadica cochinchinensis
Triadica cochinchinensis is a species of flowering plant in the spurge family, Euphorbiaceae. This tree is sometimes referred to by the common name mountain tallow tree.
The seeds are the sources of stillingia oil, a drying oil used in paints and varnishes. The fatty coat of the seeds is known as stillingia tallow, hence its common name.
The two species were formerly classified in the genus Stillingia, as Stillingia discolor and Stillingia sebifera. At some time before 1950, this tree was reclassified into the genus Sapium as Sapium discolor. In 2002 or so it was reclassified again into the genus Triadica with its present name.
