Least Concern
Small to medium-sized, evergreen tree, typically 4–8 m tall with an open, irregular canopy. Bark: Smooth, grey-brown, with occasional fissures in older trees. Leaves: Simple, oblong to elliptic, glossy dark green above, paler beneath, 6–20 cm long, with a leathery texture and strong aromatic scent when crushed. Flowers: Solitary or paired, large (4–6 cm), with thick yellow-green petals; borne on the trunk, branches, or twigs (cauliflory). Fruits: Large, oval to heart-shaped (15–30 cm long), weighing up to 2–4 kg; dark green skin covered with soft, curved spines; pulp is juicy, white, fibrous, with a sweet-tart flavour; contains numerous smooth, black seeds.
Thrives in warm, humid climates with annual rainfall between 1,000–2,500 mm. Prefers well-drained sandy loam or loamy soils; intolerant of waterlogging. Pollinated mainly by beetles and small insects.
Food: The fruit is eaten fresh, juiced, or made into ice cream, jams, smoothies, and desserts. Medicinal: Leaves, bark, roots, and seeds are used in traditional medicine for anti-inflammatory, antimicrobial, and purported anticancer properties (note: seeds are toxic and should not be ingested raw). Agroforestry: Often intercropped with other fruit trees; provides shade and habitat for wildlife. Economic Value: High market demand for both fresh fruit and processed juice.
