Ecology
Upper montane forest.
Morphology General Habit
Trees 4 – 8 m high
Morphology Leaves
Leaves spirally arranged, loosely grouped towards twig tips; petioles variable in length, 2 – 6 cm long, 1.5 – 2 mm wide, densely brownish-velvety to -pubescent when young, glabrescent, mostly rounded or flat in apical third above, occasionally slightly shallowly grooved, apex distinct from leaf-base, usually somewhat swollen, sometimes slightly swollen and geniculate at base; blades coriaceous, mostly elliptic, sometimes ovate-elliptic or -oblong, 1.7 – 2.5 × as long as wide, 8 – 14 × 4 – 7 cm, mostly acuminate, acute to obtuse at apex (70 – 100°), mostly rounded at base, sometimes broadly cuneate, sometimes slightly glossy above, very young leaves densely brownish-felty to -velvety throughout, when mature glabrous beneath or puberulous on blade, hairs straighter on veins, with 7 – 8 pairs of main lateral veins (obscure and difficult to count from above) at 60 – 70° to midrib, fine venation network obscure or somewhat raised above with areoles squarish and less than 2 mm across, midrib prominent beneath, main lateral veins scarcely prominent beneath and branching ½ – ¾ inside margin, domatia absent beneath, without dark dots beneath, margins entire to ± entire
Morphology Leaves Stipules
Stipules caducous, oblong to narrow-triangular, 3 – 4 mm long, slightly concave dorsally, tough, tip ± acute (not sharp), ± glabrous, entire
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens probably c. 20; anthers apparently with incipient awns
Morphology Reproductive morphology Flowers Calyx
Sepals in bud glabrous outside and obviously long-hairy and strongly keeled inside
Morphology Reproductive morphology Flowers Corolla
Petals in bud glabrous outside, apparently weakly keeled inside
Morphology Reproductive morphology Flowers Disc
Disk in fruit, a ring of small teeth, 0.5 mm high
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 2-locular, ovules 4 per loculus (from fruit)
Morphology Reproductive morphology Flowers Pedicel
Pedicels 15 – 21 mm long in fruit
Morphology Reproductive morphology Fruits
Fruits ovoid or ellipsoid, 1.1 – 1.5 cm long when dried, pointed at apex, rounded at base, glabrous, mesocarp c. 0.5 mm thick; stones ovoid to ellipsoid, 1 – 1.4 cm long, surface with sutures distinct throughout as grooves, lacking longitudinal ridges, crests or wings, ± tuberculate to strongly so, a few minute arches (or ‘bridges’) may be present, terete at midpoint but flattened towards apex, stone wall < 2 mm thick, loculus 1, central, roughly circular; seed 1, embryo curved and narrow, with entire endosperm.
Morphology Reproductive morphology Inflorescences
Racemes borne behind the leaves, 3 – 5 cm long, axis c. 0.8 mm thick at about halfway and sparsely ± adpressed-hairy; flowers probably 8 – 10 per inflorescence scattered throughout raceme nearly to base, bisexual, 5-merous; bracts persistent to bud at least, ovate, broad and cupped at base, rather thick and tough, 2 – 3 mm long, glabrous on the back or with a small tuft of short straight gingery hairs at base, entire and lacking basal ‘stipules'; bracteoles absent; pedicels c. 4 mm long and strongly down-curved in bud; buds ovoid, acute at apex
Morphology Twigs
Twigs 2.5 – 5 mm thick on current growth, persistently densely brownish-velvety to -pubescent, with non-resinous, hairy terminal buds
Note
Probably a member of the Coilopetalum group; differs from Elaeocarpus multiflorus (Turcz.) Fern.-Vill. in having the young growth densely brownish-velvety (not glabrous or with a few adpresed hairs), leaf margins entire (not shallowly serrate), the racemes up to 5 cm long (not 5 – 15 cm). Known only from the type. This distinctive species somewhat resembles Elaeocarpus takolensis Coode from Sulawesi, also of the Coilopetalum group (Coode 2001b: 851) in appearance, in its dense brown floccose indumentum on the young parts and in the stipules’ being longer than usual in Elaeocarpus. See Table 1 for distinctions. Unfortunately, the flower buds are too young to establish whether the ovary and disk are glabrous or hairy; if glabrous, then this species might belong instead in the Oreocarpus group (Coode 2019, in press), close to E. culminicola Warb., which it resembles in its petals’ being glabrous outside — see Table 2 for distinctions. Elaeocarpus alanganorum is easily distinguished (by its thick coriaceous leaves) from all known specimens of E. culminicola (including E. pendulus Merr.) from the Philippines, except one — Mandia 435, also from Mt Halcon, which has rather similar coriaceous leaves (see Coode 2019).
Type
Philippines, Mindoro, Naujan, NE Mt Halcon, following Paitan access trail, c. 2000 m, fl. buds & fr. 3 May 1995, Mandia 495 (holotypus K! (K000708302 & isotypus: K000708303); isotypus Herb. De La Salle University, Manila).
