Description.
Shrub to trees 2-30 m tall, D.B.H. 1-35 cm; young branches pubescent to tomentose to glabrous, old branches slightly tomentose to glabrous. Leaves with margin flat to slightly revolute. Petiole 2.5-35 mm long, 1-9 mm wide, pubescent to tomentose to glabrous. Leaf lamina 65-750 mm long, 20-250 mm wide, length:width ratio 2.1-6.2, elliptic to obovate to oblong, coriaceous, base acute to decurrent to rounded to subcordate, apex acute to acuminate, acumen 0.5-38 mm long; surface above glabrous, surface below pubescent to glabrous when young, glabrous when old; midrib impressed above, raised below, glabrous above, pubescent to glabrous below; secondary veins 8-41 pairs, brochidodromous to weakly brochidodromous, impressed above, raised below; tertiary veins reticulate. Inflorescences borne on trunk, on branches or axillary, composed of 1-11 sessile to pedicellate flowers. Flower pedicel 0-65 mm long, 1-9 mm in diameter, pubescent to glabrous. Flowers bisexual, buds globose to ovoid, sessile to pedicellate, 2-22 mm high, 4-30 mm in diameter, pubescent. Bracts 1 to 6, upper bract 1-35 mm long, 1-50 mm wide, depressed ovate to ovate, generally adpressed, enclosing the bud or semi-clasping the pedicel, pubescent outside, glabrous to pubescent inside. Sepals 3, 3-55 mm long, 2.5-43 mm wide, valvate or imbricate, free or fused at base, pubescent outside, glabrous inside, green to brown. Outer petals 3, 10-70 mm long, 9-47 mm wide, length:width ratio 0.9-2.5, ovate to elliptic, pubescent outside, puberulent to glabrous inside, cream to brown to wine red outside, cream with dark red at base to wine red inside. Inner petals 3, 10-53 mm long, 5-38 mm wide, length:width ratio 0.9-2.4, elliptic to obovate, pubescent outside, puberulent to glabrous inside, cream to brown to wine red outside, cream with dark red at base to wine red inside. Stamens 200 to 3000, 1-5 mm long, 0.1-0.7 mm wide, anthers linear, connective prolongation truncate. Carpels 5 to 160, 1-7 mm long, 0.5-2.2 mm wide, pubescent, free; stigma 0-2 mm long, 0.5-2 mm wide, coiled, pubescent, generally covered with an exsudate at anthesis. Fruiting pedicel 0-31 mm long, 2-8 mm in diameter, pubescent. Monocarps 1 to 80, 17-90 mm long, 4.5-32 mm wide, length:width ratio 1.3-11, generally cylindrical, pubescent to glabrous, green to orange to red to dark-blue black; sessile to stipitate; stipe 0-12 mm long, 1-10 mm wide, pubescent to glabrous. Seeds 1-18 per monocarp, uniseriate to biseriate, 3 to 29 mm long, 2-11 mm wide, ellipsoid to semicircular.
