Syzygium furfuraceum Merr.& L.M.Perry (1942) 276. — Type: Clemens 2133 (holo A n.v.; iso L!, NY!), Papua New Guinea, Morobe Province, Sattelberg, Quembung Mission , alt. c. 600 m, 23 Mar. 1936.
Tree to 30 m tall, to 60 cm dbh; bark light to dark brown, pus- tular or flaky. Vegetative branchlet terete, rounded, 3‒4 mm diam; bark dull, smooth, not glandular-verrucose, persistent. Leaf lamina broadly oblong or sometimes obovate, 8.5‒19.5 by 3‒10.3 cm, 1.8‒2.6 times as long as wide; base obtuse; apex obtuse, acute or sometimes short-acuminate; acumen flat; margin flat; coriaceous; primary and secondary venation distinctly different with secondaries relatively little developed and not or rarely joining the intramarginal vein; primary veins 30‒37 on each side of the midrib, in median part of lamina at a divergence angle of 60‒70° and 4‒7 mm apart; intramarginal vein present, weakly arched, 3‒5 mm from margin, secondary intramarginal vein present. Petiole 5‒12 mm long. Reproductive seasonal growth unit with a reproductive zone only. Inflorescence leafless, cauline, paniculate, up to 16 by 12 cm, major axis 4‒5 mm thick at the midpoint, bark furfuraceous; bracts caducous; bracteoles subtending each flower, caducous. Flower buds with the apex rounded to obtuse. Flowers white, cream, green or greenish white. Hypanthium dull, smooth or striate, furfuraceous, not visibly gland-dotted; stipitate or not (hypanthium then tapering evenly to the base or truncate or rounded); to cup-shaped or narrowly subcampanuloid, 4.5‒6 by 5‒6 mm, stipe 0‒0.5 mm long. Calyx is an undulating rim of tissue, typically well developed, with 4 well-distinguished lobes; lobes transversely semi-elliptic or transversely narrowly semi-elliptic, c. 1‒1.25 mm long including the rim. Petals calyptrate (coherent and falling as a cap). Staminal disc flat ( Fig. 2 View Fig : 1.1, 1.3 or 1.4). Stamens 115‒120(‒150), 6‒13 mm long. Style 4‒5.5 mm long (seen up to 7.5 mm long on developing fruit). Placentation axile-basal; placenta a small cushion. Ovules 15‒26 per locule, ascending, arranged irregularly. Mature fruit pink, red or magenta, smooth in vivo, wrinkled and ribbed in sicco, furfuraceous, depressedly spheroid; c. 15 by 20‒30 mm excluding the calyx, with the hypanthium rim appreciably expanding in fruit and 7–10 mm diam; seed depressed spheroid, 15‒20 mm across, cotyledons collateral.
Distribution — Papua New Guinea.
Habitat & Ecology — Hill forest, alluvial forest, lowland primary hill forest, lowland rainforest above swamp, stunted lowland forest on exposed ridge, co-dominant in upper mid-mountain forest, Anisoptera -dominated forest, dry rainforest. Altitude 0‒1280 m.
Note — Although furfuraceous in the early stages of development, the hypanthium may not be furfuraceous at anthesis, e.g., in Clemens 8107A. The inflorescences once were noted by a collector as being among the leaves instead of terminal.
