Distribution
Papua New Guinea (Bismarck Archipelago).
Morphology General Habit
Trees 10 – 30 m high with dense umbrella crown and dark foliage Trees 10 – 15 m high, often buttressed, sometimes also stilt-rooted Trees 8 – 15 m high Trees 24 – 27 m high
Morphology Leaves
Leaves with petioles 0.2 – 0.5 cm long, 3 – 6 mm thick and strongly flattened with wide flanges, glabrous or with sparse, short, adpressed hairs, rounded or flat above, distinct from leaf-base (the flanges merge into the leaf-base but at a sudden constriction), not swollen at either end; blades chartaceous, obovate, 2.8 – 3.2 × as long as wide, 29 – 35 × 10 – 12 cm, probably usually with a short acumen (but many tips damaged in herb.), obtuse to broadly obtuse at apex (80 – 110°; only c- 3 tips seen), tapering towards a narrowly rounded or narrowly cordate base, dull above, when very young with sparse silky hairs above, glabrous or with some sparse, short, adpressed hairs beneath, midrib prominent beneath, with 16 – 20 pairs of main veins prominent beneath and breaking up ½ - ⅞ towards margin, domatia absent or rare beneath, without minute dark dots beneath, margins weakly serrate (but many damaged by insect attack), serrations apparently similar throughout the leaf-length, teeth 3 – 7 mm apart with hairpoints adpressed Leaves with petioles 0.4 – 1 cm long, 1 – 2 mm wide, glabrous or hairy like the twigs, rounded or flat in apical third above; blades coriaceous, mostly elliptic, sometimes obovate- or oblong-elliptic, (2 –) 2.2 – 2.8 (– 3.2) × as long as wide, 6.5 – 11 (– 12.5) × 2.5 – 5 (– 5.5) cm, not usually acuminate, rarely a short broad acumen present, mostly obtuse to broadly obtuse at apex, rarely acute (50 –) 60 – 110°, cuneate to broadly cuneate at base, glossy above, usually glabrous beneath, eastern specimens (Clemens 5019 and NGF 42155) may be sparsely adpressed-hairy, with 8 – 14 pairs of main veins (somewhat variable; often intermediate veins almost as strong, then difficult to count), fine venation network sometimes somewhat raised above, midrib and main veins prominent beneath and breaking up variably ½ - ⅞ inside margin, domatia present in vein axils beneath in the western specimens but lacking from the eastern specimens, margins weakly serrate, sometimes less serrated in lower half, teeth (1 –) 2 – 5 mm apart Leaves spirally arranged, loosely grouped towards twig tips; petioles 4 – 9 cm long (perhaps more, the very narrow-cuneate base of the blade makes measuring difficult), 0.8 – 1.5 mm wide, glabrous or almost so, flat in apical third above but side-flanges can be tipped up, merging into decurrent leaf-base, not swollen or geniculate at either end; blades chartaceous, elliptic to sometimes obovate-elliptic, 3.1 – 4 × as long as wide, 4 – 7 × 1 – 2.2 cm, rarely somewhat acuminate, a few slightly so, narrowly acute to acute at apex (40 – 50 ( – 60)°, narrowly cuneate at base, glabrous beneath when mature, with 9 – 11 pairs of main veins, fine venation network neither prominent nor impressed above, midrib prominent and main veins scarcely prominent beneath so vein number difficult to discern, breaking up ½ - ¾ inside margin, domatia absent or rare beneath, margins weakly serrate, clearly less serrated in lower half, teeth 1.5 – 3 mm apart
