Conservation
Known with certainty from the type only. Only known from Mt Piora and apparently not collected since 1972; there must be some concern for this.
Ecology
Ridge in moss-forest, low canopy. 'Common from 2580 - 2760 m, perhaps higher'.
Morphology General Habit
Shrub or gnarled tree to c. 4.5 m high
Morphology Leaves
Leaves loosely grouped towards twig tips; petioles straight, stiff, 0.4 - 1.2 cm long, ± adpressed- hairy at first, glabrescent, distinctly grooved above, distinct from leaf-base, swollen and geniculate at apex, usually geniculate at base; blades chartaceous to coriaceous, ovate (to sometimes ovate-elliptic), 1.6 - 2.1 x as long as wide, 2.2 - 4 x 1.4 - 2 cm, sometimes weakly acuminate, acute to obtuse at apex, broadly cuneate to broadly rounded at base or tapering towards a narrowly rounded or broadly cuneate base, dull above, very young leaves densely adpressed hairy on both sides, glabrous or somewhat adpressed-hairy beneath when mature, with 5 - 7 pairs of main lateral veins (difficult to tell from intermediate veins), fine venation network clear and raised above, areoles squarish, less than 2 mm across, midrib prominent beneath, main laterals scarcely prominent beneath and breaking up 1/2 to 3/4 inside margin, with domatia along midribs regularly present beneath, weakly serrate, teeth 2 - 3.5 mm apart
Morphology Leaves Stipules
Stipules sometimes persistent, narrow-linear, flexuous, densely hairy on back like twigs, glossy and glabrous inside, 3 - 7 mm long, entire
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 15, inserted between disk and ovary, persisting longer than both sepals and petals; filaments straight to somewhat incurved or with a few slightly curled, 1.5 mm long, tapering slightly from base to apex, with a few minute ascending hairs in distal half; anthers minutely hairy, 2 mm long, the outer tooth slightly longer than inner, acuminate, sometimes tipped with short setae longer than the hairs elsewhere on the anther
Morphology Reproductive morphology Flowers Calyx
Sepals falling earlier than stamens, 7 x 2 - 2.5 mm, with dense short slightly adpressed gingery hairs outside, with a few short hairs inside
Morphology Reproductive morphology Flowers Corolla
Petals thick- membranous, narrow obovate to elliptic (but so incurved as to be difficult to decide), 6 mm long, 3 mm wide at widest point of limb, rounded at apex, with 7 - 10 apical very irregular divisions (thus difficult to count), divisions ± narrow-triangular and 0.5 - 1 mm long, acute to obtuse at tip, densely hairy outside at least as far up as petal division, hairs glossy golden, dense, margins densely hairy, glabrous inside except for an isolated central patch of golden hairs about 2/3 way up, keel absent inside, flat or incurved at base, without any pockets
Morphology Reproductive morphology Flowers Disc
Disk annular, weakly toothed, 0.5 mm high, short-hairy
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary placed above the disk, 1 mm long, densely pilose, 2-locular; ovules 4 - 5 per loculus; style 3.5 mm long
Morphology Reproductive morphology Fruits
Fruits oblong, 1.3 x 0.7 mm when dried, terete, rounded or obtuse at apex, rounded at base, mesocarp c. 1 mm thick; stones oblong, 1.1 cm long, surface rugose, wall less than 2 mm thick, loculus 1, central; seed 1; embryo straight, broad, with entire endosperm.
Morphology Reproductive morphology Inflorescences
Racemes among current leaves, 1 - 1.8 cm long, the axis somewhat adpressed-hairy, 2-flowered, flowers bisexual, 5- merous; bracts early caducous, not seen (but minute bract 'stipules' present); pedicels 5 - 7(- 8) mm long, much hairier than the axis; buds ovoid, obtuse at apex
Morphology Twigs
Twigs with persistent fairly long, straight almost adpressed golden hairs, twigs 1.5 mm thick towards the tip, with non- resinous, hairy terminal buds
Note
The young leaves were creamy-pinkish-hairy and, in this, resembled two species of Sericolea (NGF 46279 S. microphylla Balgooy and 46280 S. brassii A. C. Sm.) growing together with the Elaeocarpus in the same vegetation. (Such pinkish young leaves are also known in other species of Elaeocarpus, from mid- to high-altitude from Borneo, e.g. E. knuthii Merr.). Flowers creamy, nodding; fruit blue, smooth ? ovoid. Two other collections from Mt Piora, both at LAE, Coode 3881 and 3900 were also listed in Coode 1978: 210 as Elaeocarpus crenulatus, and these too presumably represent E. amabilis subsp. piorae. Elaeocarpus schoddei has leaves 6.5 - 7 x 2.5 - 3 cm and is known from a small area near Port Moresby at 450 - 700 m. This does share certain characteristics with E. myrtoides and E. amabilis - short few-flowered racemes, small flowers, 5 - 7-fid petals somewhat hairy outside, ± inconspicuous annular disk, 10 - 15 stamens, anthers without awns, 2-locular ovary, ovules 6/loculus - but fruits (and thus seeds and embryos) are unknown.
