DESCRIPTION

Trees, to 10 m. Twigs terete, glabrous; terminal buds glabrous. Leaves opposite, 4-6.5 × 1-2.5 cm, elliptic, broadly elliptic or obovate, glabrous, firmly chartaceous, base acute or attenuate, apex obtuse or emarginate, margin flat, cartilaginous, lateral veins not always clearly visible, 5-7; petioles c. 5 mm long, canaliculate. Inflorescences to 2 cm long, glabrous, up to 7-flowered, flowers gradually narrowed into the pedicel. Flowers glabrous, 4 mm in diameter, yellow-green, tepals 2 mm long, 1-1.5 mm wide, spreading at anthesis; stamens 6, with a short filament, bending outwards at anthesis with the tepals, pubescent at the base, staminodia III columnar, the tips somewhat peltate, arching outward, free, not forming a shield, smaller than the stamens, staminodia IV minuscule, stipitiform, pubescent, hidden between staminodia III; rim of the hypanthium and base of the stamens and staminodia pubescent; pistil and inside of receptacle glabrous. Fruits ellipsoid, 3 × 1.5 cm, smooth, crowned by the floral remnants.

REMARKS

Aspidostemon parvifolium is easily recognized by its rather small leaves with obtuse or emarginated apex, the few-flowered inflorescences and the spreading tepals at anthesis. It is the only species of Aspidostemon with short filaments; all other species have stamens with a broad base. It has only been collected in coastal forest on sand near Fort Dauphin ( Fig. 15 View FIG ). Vernacular names have not been recorded.
