Morphology General Buds
Flower-buds oblong-ovoid, rounded to obtuse at apex
Morphology General Habit
Trees 12 m high
Morphology Leaves
Leaves spirally arranged, loosely grouped towards twig tips
Morphology Leaves Leaf lamina Leaf margin
Margins ± entire or weakly serrate, serrations similar throughout the leaf-length, teeth 5 – 15 mm apart
Morphology Leaves Petiole
Petioles 0.5 – 1.8 cm long, 0.5 – 1.3 mm thick, glabrous or hairy like the twigs, not verrucose when mature, rounded or flat in apical third above, distinct from leaf-base, swollen and without or with a pair of pegs at apex (3 specimens show some teeth, others can have a pair just above lamina base), obviously swollen and usually geniculate at base (one of the most obviously swollen/geniculate species); blades chartaceous, obovate, (1.7 –) 1.8 – 2.3 × as long as wide, 5.5 – 10 (– 14.5) × 3 – 5 (– 7) cm, usually not acuminate (Milliken 875 has short broad acumens), obtuse to broadly obtuse (80 – 110°) to rounded at apex, narrowly cuneate to cuneate at base, dull above, glabrous beneath when mature, not or scarcely verrucose when mature, with 8 – 11 pairs of main veins at 60 – 80° to midrib, fine venation network obscure above, midrib prominent beneath, main laterals scarcely to only somewhat prominent beneath and breaking up variably 1/2 – 7/8 inside margin, domatia absent beneath, without minute dark dots beneath
Morphology Leaves Stipules
Stipules caducous, subulate, minute, hairy like twigs at base, glossy-glabrous distally, 0.4 – 1 mm long, entire
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 13 – 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 glabrous or minutely fairly densely hairy (scarcely hairs, more like asperous papillae), 0.8 – 1 mm long, with outer and inner teeth of about the same length, both teeth rounded and without awn, beak or setae at tip
Morphology Reproductive morphology Flowers Calyx
Sepals persistent after petals and stamens have fallen, 2 – 2.5 × c. 1 mm, with some ± adpressed soft short hairs outside, medium-dense hairy inside with hairs short, not adpressed, not verrucose outside at anthesis, obviously keeled inside at base, fading towards tip
Morphology Reproductive morphology Flowers Corolla
Petals thick-membranous, just translucent, obovate, narrowed in lower third but not constricted into a claw, 2 – 2.2 mm long, 0.8 – 1.3 mm wide at widest point of limb, rounded to truncate at apex, with 10 – 13 apical divisions mostly ± equal and sometimes in pairs or 3s, scarcely lobed, divisions narrow, linear, 0.3 – 0.5 mm long, swollen and incurved at tip, petals not verrucose in dried material, glabrous outside, margins minutely velvety to densely short-hairy throughout, densely short-hairy inside, keel absent inside or sometimes ± present as a thickened base, 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- to medium-hairy
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovaries submerged in or surrounded by the disk, conical or nearly so or sometimes narrowed at base, 0.7 mm long, densely short- to medium-hairy, 3-locular; ovules 2 per loculus; style tapering to a point, 0.7 – 1.2 mm long
Morphology Reproductive morphology Flowers Pedicel
Pedicels 3 – 4 mm long, 0.3 – 0.4 mm thick in flower Pedicels 4 – 5 mm long in fruit
Morphology Reproductive morphology Fruits
Fruits ellipsoid, 2.5 – 2.9 cm long when dried, terete, pointed at apex, cuneate at base, glabrous or virtually so; mesocarp < 2 mm thick; stones ellipsoid to fusiform (borderline), 2.4 – 2.8 cm long, surface without persistent fibres, sutures on surface obscure or visible in apical half at least, without longitudinal ridges, crests or wings, surface smooth, rugose or with mostly longitudinal grooves and rounded sculpturing between (borderline), not flattened even at apex, wall 2 – 4 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 them, 2 – 7 cm long, axis 0.5 – 0.7 mm thick at about halfway and with sparse to fairly dense, short, straight, adpressed or between adpressed and spreading hairs, 8 – 24-flowered (southern specimens perhaps with shorter inflorescences and fewer flowers), scattered throughout raceme nearly to base, bisexual, 5-merous
Morphology Reproductive morphology Inflorescences Bracts
Bracts early caducous, oblong to narrowly obovate-boat-shaped; hairy like the rachis on both sides, 2 – 2.5 mm long, entire; bracteoles on pedicels absent
Morphology Twigs
Twigs 1.5 – 2.5 mm thick towards the tip, hairy at tip, with sparse to fairly dense, short, straight, ± adpressed hairs; terminal buds non-resinous, hairy
Note
Fruiting material of this can be difficult to distinguish from Elaeocarpus cumingii Turcz. (sect. Elaeocarpus) which is also known from Sulawesi. Both have ellipsoid fruit and the stones of both are weakly ‘longitudinally-rugose’; however, the stones of the Dactylosphaera group are nearly always fusiform, while in sect. Elaeocarpus only E. submonoceras Miq., E. acmosepalus Ridl. and E. acmocarpus Weibel (all unknown from Sulawesi) have fusiform stones. The problem can be illustrated by the fruiting Milliken 875 above, from northern Sulawesi where both species are known in flower. I originally determined this as E. cumingii, but now think (on the evidence of the thicker leaves drying greyish, not papery leaves drying brownish) that it is probably E. celebicus. The stones are oblong-ellipsoid, tapering to the ends more than would be usual in E. cumingii but not really fusiform. Flowers would immediately reveal to which group this belongs.
