Characteristics

Tall tree 4.5–27(–30) m. tall, with smooth pale grey or grey-brown bark and numerous stilt roots; young shoots finely adpressed ferruginous pubescent, but very soon glabrous, older shoots with longitudinally rugose grey-brown bark.. Leaf-blades oblong to elliptic, oblanceolate or ovate-lanceolate, (7–)9–21.5 cm. long, (2.2–)4–8.5 cm. wide, obtuse to ± abruptly acuminate at the apex, rounded to cuneate and slightly decurrent at the base, thinly to thickly coriaceous, glabrous and drying bluish-or dull green above, finely adpressed pubescent or glabrescent and drying a distinct orange-brown colour beneath (but grey in life); venation finely reticulate and often prominent on both surfaces or obscure above; petiole 0.5–1.8 cm. long, glabrescent or finely pubescent.. Flowers solitary or in 2–5-flowered fascicles; pedicels 4–6 mm. long, adpressed ferruginous pubescent; bracteoles 2–5, oblong, 2 mm. long.. Sepals ovate-triangular, 2–4 mm. long, 2–3 mm. wide, acute to apiculate, adpressed pubescent outside, glabrous and often crimson inside.. Petals very unequal; outer orange-yellow or greenish-yellow, mostly crimson at the base within, narrowly linear-lanceolate, but widened and concave at the base, (2–)2.6–3.7 cm. long, 3–4 mm. wide, 3-angled above, silky ferruginous pubescent outside, puberulous within save at base; inner crimson, rhomboid to oblanceolate or elliptic, 5–8 mm. long, 2.5–3.5 mm. wide, apiculate, keeled, concave, silky pubescent above outside, otherwise glabrous.. Stamens linear, ± 2 mm. long; connective-prolongation obliquely capitate, papillose.. Carpels 8–11; ovary cylindrical, ± 1.5–2 mm. long, adpressed pubescent with simple or 2-branched hairs, 9–10-ovuled; style linear, 2–3.5 mm. long, papillate.. Fruiting pedicels 1–1.5 cm. long; monocarps 1–11, green, ± cylindrical, 2–7 cm. long, 0.8–1.2 cm. wide, curved, apiculate, 1–8-seeded, ± constricted between the seeds, glabrescent, finely rugose; stipes 0.5–1 cm. long.. Seeds reddish-brown, globose to cylindric, 0.7–1.2 cm. long, 5–9 mm. wide and thick, vertical; aril 2–4 mm. long, made up of many filaments.
