Nephelium daedaleum


Tree, up to 33 m high, dbh up to 70 cm, sometimes with buttresses. Leaves 1-3(-5)-jugate; Inflorescences terminal. Sepals nearly free, c. 3 mm long. Petals 4 or 5, 1.75-2 by 1.5-2 mm, the claw up to 1 mm long, the blade auricled to funnel-shaped, at least claw and outside of blade densely woolly. Stamens 8 (sometimes less?). Ovary 2-celled. Fruits flattened-ellipsoid, bulging at base to the abaxial side, 4 by 2.25 by 1.5 cm, densely shortly pubescent, fairly densely set with pyramidal warts c. 1.5 mm high, deeply irregularly fissured longitudinally (possibly thin-fleshy when fresh and rupturing only when dry; after boiling the surface closes up and the fissures are glabrous inside);


Asia-Tropical: Borneo present (Sabah present, Sarawak present)
Malesia: Borneo (Sarawak and Sabah).


Sometimes cultivated, probably because of the fruit.


Specimens of this species may key out as N. hamulatum, which differs in shorter petiolules that are narrowly deeply grooved above, smaller stiff-coriaceous leaflets, the usually barely evident intercalated veins, the far shorter sepals, and above all the distinct differentiation of the fruit appendages into a broad basal and a narrowed apical part.
