The Artocarpus hirsutus grows in altitudes ranging from sea level to an elevation of 1000 m in places with an annual rainfall of 1500 mm or more. They are endemic to the Western Ghats and are found in its evergreen forests. The canopy tree can reach a height of up to 35 m and about 4.5 m in girth.[5]

The tree is prized for its durable timber which is comparable in quality with teak. The timber was used extensively in the construction of ceilings, door frames and furniture in older buildings, especially in Kerala.[6] The famous snake boats of Kerala are often hewn out of the Aini's wood.[7] 140 tons of A. hisutus wood from Kerala was used for Tim Severin's ship Sohar, in which he traveled from Muscat to Canton in 1980-81.

Its flowers are, unisexual, in axillary inflorescences and its fruits are syncarps and very sweet, changing to an orange hue when ripe. Its simple, alternate leaves will ooze latex if broken. It is harvested for its wood.[3][4]
