Canarium macadamii Leenh.

Large tree, 30-40 m by ¾-1 m. Branchlets slender, somewhat scabrous, lenticellate; pith with a peripheral cylinder of vascular strands, central ones more or less clearly cylindrically arranged. Stipules inserted at the base of the petiole, linear, 5-6 mm, glabrous, as are the leaves and the inflorescences. Leaves 2-4-jugate. Leaflets oblique-ovate, 10-20 by 6-8 cm, subcoriaceous; base very oblique, rounded; margin entire; apex abruptly, shortly (5 mm) blunt-acuminate; nerves 14-16 pairs (angle 60-70°, in the basal part up to 90°), straight to slightly curved, vaguely to distinctly arching close to the margin. Inflorescences axillary, narrowly paniculate, c. 12 cm long; branches up to 2½ cm, with up to 15 clustered flowers. Female inflorescences 8-10 cm long. ♀ Flowers 7 mm; calyx 4 mm; petals outside sparsely hairy; staminodes confluent with the disk; disk glabrous, protruded into 6 tongue-shaped, fleshy, 2 mm long lobes alternating with and nearly equalling staminodes. Flowers (male) 7 mm long, short-pedicelled, glabrous outside, with a slightly concave receptacle. Calyx 4.5 mm high. Stamens slightly confluent at base. Disk conical, 1.5 mm high, halfway with a 6-lobed rim, glabrous, with a central canal, widening to the base and enclosing the rudimentary pistil. Infructescences 8-15 cm long, calyx flat, triangular, 5-7 mm diam., lobes reflexed. Fruits ellipsoid, round in cross-section, 3½ by 1½ cm, acuminate at the apex, glabrous; pyrene smooth; lids 3 mm thick. Seed 1, sterile cells moderately reduced.

A canopy tree that is locally common on forested slopes, on rich clay or loam soil, at elevations from 1,100-1,500 metres.
