Description and Ethnobotany

Growth Form	It is a tree which can reach up to 35 m tall and sometimes develop buttresses. It produces white sap when any part of the plant is injured.
Foliage	Leaves are leathery. Mature leaves are elliptic, about (3-) 6 – 18 (-33) cm long and (1.5 -) 3.5 – 9 cm wide, while young leaves are pinnately lobate. Both the leaf tip and leaf base are variable. The leaf tip can be tapering (acuminate), caudate, acute, obtuse or rounded. While the leaf base can be wedge shaped (cuneate), narrow (subattenuate), rounded to subcordate. Both the upper surface and lower surface of the leaf can be glabrous or sparsely covered with hairs on the midrib and veins. Each leaf has 7 – 10 lateral veins. Petiole is short (0.5–2.5 cm long), and sparsely covered with whitish to brownish appressed hairs. Stipule is 0.2 – 0.4 cm long, falls out early and covered with whitish to brownish appressed hairs.
Flowers	Inflorescence occurs at the axillary position. Male inflorescence is subglobose, narrowly ellipsoid to club-shaped (clavate) while female inflorescence is subglobose to ellipsoid.

Fruit	Fruit is subglobose, up to 3 – 4 cm diameter, and can be sparsely or densely covered with velvety hairs.
Habitat	It is found in rainforest, up to 1600 m altitude.
Associated Flora	Flowers are pollinated by insects.
Cultivation	t can be propagated by seed.
Etymology	The genus epithet Artocarpus comes from the Greek words 'artos', meaning bread and 'karpos', meaning fruit.
