|Vernicia fordii (tung tree; syn. Aleurites fordii) is a species of Vernicia in the spurge family, native to southern China, Burma, and northern Vietnam. Other vernacular names include tung oil tree, tung-oil tree, tungoil tree, China wood-oil tree, kalo nut tree, 油桐 (lit. oil tung) being the formal name in Chinese.
It is a small to medium-sized deciduous tree growing to 20 m tall, with a spreading crown. The bark is smooth and thin, and bleeds latex if cut. The leaves are alternate, simple, 4.5–25 cm long and 3.5–22 cm broad, heart-shaped or with three shallow, maple-like lobes, green above and below, red conspicuous glands at the base of the leaf, and with a 5.5–26 cm long petiole. The flowers are 2.5–3.5 cm diameter, with five pale pink to purple petals with streaks of darker red or purple in the throat; it is monoecious with individual flowers either male or female, but produced together in the inflorescences. The flowers appear before or with the leaves in loose, terminal clusters. The fruit is a hard, woody pear-shaped drupe 4–6 cm long and 3–5 cm diameter, containing four or five large, oily seeds; it is green initially, becoming dull brown when ripe in autumn.
