Ecology
Primary or secondary lowland forest, on slopes or alluvial plains near rivers; sea-level to 300 (– 840) m.
Morphology General Buds
Flower-buds ovoid, obtuse to acute at apex
Morphology General Habit
Trees 9 – 24 m high
Morphology Leaves
Leaves spirally arranged, loosely grouped towards twig tips
Morphology Leaves Leaf lamina Leaf margin
Margins weakly serrate, less serrated in lower half, teeth 5 – 18 mm apart in apical half
Morphology Leaves Petiole
Petioles 1.5 – 3.5 (– 4) cm long (variable between specimens), 1.6 – 2.3 mm thick, glabrous to persistently sparsely adpressed-hairy, not verrucose when mature, rounded or flat in apical third above, distinct from or merging into decurrent leaf-base, somewhat or obviously swollen and with or without pegs at apex (some specimens have, some haven't: apparently the more pulvinate the fewer pegs?), somewhat swollen or geniculate at base; blades chartaceous, obovate, 1.8 – 2.6 × as long as wide, 10 – 23 × 4 – 10 (– 12) cm, acuminate or not (very variable in this), broadly obtuse (100 – 130°) to rounded at apex, cuneate at base, dull or glossy above (dull to borderline), young leaves ± glabrous, glabrous when mature, not or scarcely verrucose when mature, with 9 – 12 pairs of main veins at 50 – 70° to midrib, fine venation network obscure above, midrib prominent to strongly prominent beneath, main laterals prominent beneath and breaking up 3/4 – 7/8 inside margin (loops often present), domatia usually absent beneath (two specimens have a few small domatia), without minute dark dots beneath
Morphology Leaves Stipules
Stipules caducous, peg-like, minute, thin, indurate tip glabrous, the rest minutely hairy, 0.4 – 0.9 mm long, entire
Morphology Reproductive morphology Flowers
Flowers scattered throughout raceme nearly to base, bisexual, 5-merous
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 14 – 15, inserted in a ± single ring between disk and ovary, falling before sepals or petals or both; filaments straight or somewhat incurved, 0.5 – 0.8 mm long, not tapering, glabrous; anthers minutely sparsely to fairly densely hairy, 0.5 – 1 mm long, with outer and inner teeth of about the same length and rounded, sometimes tipped with short setae longer than the hairs elsewhere on the anther
Morphology Reproductive morphology Flowers Calyx
Sepals persistent after petals and stamens, 2.5 – 3 × 1.2 – 1.5 mm, sparsely hairy outside, the hairs short and adpressed, glabrous areas inside beside keel from 1/3 – 2/3, elsewhere with minute fairly dense hairs, not verrucose outside at anthesis, with low keel inside at base at least, often fading towards the tip
Morphology Reproductive morphology Flowers Corolla
Petals thick-membranous, just translucent, obovate, narrow-obovate to spathulate and sometimes ± clawed in lower third, 2.5 – 3.5 mm long (if the 'fingers' are straightened out), 1.2 – 1.5 mm wide at widest point of limb, rounded at apex, with 5 – 10 apical divisions ± equal in length, not grouped into lobes, linear, 0.4 – 0.6 mm long, swollen and incurved at tip, petals not verrucose in dried material, glabrous outside, margins densely short-hairy throughout, densely short-hairy inside, keel absent inside so petals ± flat at midpoint and at base, without any infolding of margins
Morphology Reproductive morphology Flowers Disc
Disk with free lobes, 0.5 mm high, short-hairy
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovaries placed above the disk, clearly narrowed at base, c. 1 mm long, velvety or sericeous, 3-locular; ovules 2 per loculus; style tapering to a point, 1.4 – 1.5 mm long
Morphology Reproductive morphology Flowers Pedicel
Pedicels 2 – 3 mm long in fruit Pedicels 1.5 – 3 mm long, 0.3 – 0.5 mm thick in flower
Morphology Reproductive morphology Fruits
Fruits fusiform, 3.2 – 5.2 cm long when dried, terete, pointed at apex, the apex often a curved ‘beak’ and with outside smooth or rough with small processes not reflected in stone sculpturing, cuneate at base, glabrous or rarely velvety; mesocarp probably 2 – 3 mm thick; stones fusiform, 3 – 5 cm long, surface usually without persistent fibres, sutures distinct throughout as grooves, without longitudinal ridges, crests or wings, surface rugose or with mostly longitudinal grooves and rounded sculpturing between, not flattened even at apex, wall at least 3 mm thick, loculus 1, central, roughly triangular in section; seed 1, embryo straight, broad, with entire endosperm.
Morphology Reproductive morphology Inflorescences
Racemes amongst current leaves or just behind behind them, 4 – 11 cm long, axis 0.7 – 1 mm thick at about halfway and variously hairy, the hairs sparse, short, straight, between adpressed and spreading, 16 – 40-flowered
Morphology Reproductive morphology Inflorescences Bracts
Bracts early caducous or persistent to anthesis, ± ovate boat-shaped, hairy outside, glabrous inside, 1 mm long, entire; bracteoles on pedicels absent
Morphology Twigs
Twigs 1.8 – 3.5 mm thick towards the tip, adpressed-hairy at tip; terminal buds non-resinous, hairy
Note
Usually, the mesocarp of the fruit separates fairly easily or easily from the stone, after boiling from dry. However, in two instances the mesocarp would not detach from the stone surface (Takeuchi 4955 and Craven & Schodde 1503); perhaps this is due to a stage of development (or infertility) because it seems not to be correlated with any other variation. This is the form most often collected; it has glabrous leaves varying in size 10 – 23 × 4 – 10 (– 12) cm. Fruit (but not stone) usually slightly warted.
