DESCRIPTION Tree, 20 m . Twigs terete, glabrous, lenticellate; teminal buds glabrous. Leaves opposite, 7.5-11 × 2.5-4 cm , glabrous, elliptic to ovate-elliptic, papyraceous, the base acute, apex acuminate, acumen 7-12 mm long, margin flat, reticulation immersed on the upper surface, faintly raised on the lower surface, lateral veins difficult to separate from the tertiary veins; petioles 5-8 mm long, canaliculate. Inflorescences to 1.5 cm long, glabrous; pedicels 4-5 mm long. Flowers 2-2.5 mm in diam., 1.5 mm long, glabrous, tepals about as wide as long, erect, the outer tepals thickened at their base and slightly bulging outwards; stamens 3, thick, but their tips not peltate, locelli apical, readily visible, staminodia II not seen, either lacking, reduced to a few hairs at the base of the inner tepals or fused completely with the staminodia III; staminodia III with their tips flattened, fused into a flat-topped column, and not covering any part of the stamens. Fruits ellipsoid, 2.3 × 1.2 cm , smooth, the floral remnants persisting on top. REMARKS Aspidostemon longipedicellatum can be confused with A. trianthera ; both species have basally thickened tepals that bulge outwards. The tepals in A. trianthera are more strongly thickened and give the flowers a 6-lobed appearance.Other differences are the longer pedicels in A. longipedicellatum , the fused staminodia III in A. longipedicellatum (free in A. trianthera ), the apical locelli in A. longipedicellatum (introrse in A. trianthera ) and the absence of visible hairs in the flowers of A. longipedicellatum (although a few hairs are present, but hidden, inside the flowers and are covered by the staminodia III). It is only known from the NE part of Madagascar ( Fig. 10 ). The fruiting paratype was initially identified by Kostermans (in sched.) as a new species; later he cited it as a paratype of A. trianthera . ALTITUDINAL DISTRIBUTION 0-600 m . PHENOLOGY Flowers: February, November, December; fruits: November. VERNACULAR NAME Tapiramena.
