Artocarpus rigidus

Artocarpus rigidus, commonly known as the monkey jack, is a tropical evergreen fruit tree belonging to the Moraceae family. It is a significant species native to Southeast Asia, closely related to the better-known breadfruit and jackfruit trees, providing both culinary and ecological value in its native habitats.

The native range of the species encompasses the moist tropical forests of Indonesia, Malaysia, Thailand, and the Philippines. As an understory or canopy tree, it thrives in regions with abundant annual rainfall and stable, warm temperatures, making it an essential component of the lowland rainforest biodiversity.

Botanically, this tree can reach substantial heights of up to 25 meters. Its foliage consists of large, stiff, and leathery leaves that are slightly hairy on the underside. The fruits are multiple, rounded structures with thick rinds covered in soft spines, protecting the sweet, yellow to orange edible pulp inside, which contains several seeds.

Cultivation of Artocarpus rigidus requires a tropical climate with no frost and high moisture levels throughout the year. The soil must be deep, fertile, and well-drained, as the tree is sensitive to waterlogging. In terms of maintenance, regular mulching and proper spacing are crucial to ensure healthy growth and optimal fruit production in plantation settings.

The primary use of the monkey jack is for its edible fruit, which is highly appreciated in local markets for its sweetness and unique aroma. Furthermore, the tree provides high-quality timber that is resistant to environmental decay, making it useful for local construction and woodworking. It also serves as a critical food source for local wildlife, contributing to forest ecosystem services.

• High humidity is essential for successful flowering.
• Propagated primarily through seeds or budding techniques.
