Artrocarpus heterophyllus

Jackfruit, jakfruit

A tree up to 15 m high with stiff trilobed leaves on the young shoots. The most unusual fruits are green and clump-formed with a papillate surface, weigh up to 25 kg each and can be 1 m long. They grow all along the trunk of the tree. Despite the unpleasant odour the fruits are an important food in the eastern tropics.

Jack leaf is a staple roughage for goats in Kerala, India. Its crude protein digestibility is fairly low because of its high content of tannins. Cattle also relish the rind of the ripe fruit.
