Information
Shrub or small tree, 1.5–9(–14) m tall, all parts glabrous; bark coarsely furrowed; slash bright crimson; branches somewhat flattened and sometimes rather pendent. Leaves usually alternate, elliptic or elliptic-oblong, rarely obovate, 1.5–6.5x0.7–4 cm, abruptly apiculate, base cuneate, veins ± immersed, only midvein raised beneath and running back down stem in a narrow ridge; petiole 1–3 mm long, articulated to a small cushion. Flowers either hermaphrodite or male, plants androdioecious, hermaphrodite flowers in axils of upper leaves; peduncles solitary, usually 1-flowered, occasionally flowers in 2–3-flowered dichasia; male flowers both axillary and terminal, often panicled, each peduncle usually terminating in an umbellate cluster of flowers, rarely flowers solitary or in a 2–3-flowered dichasium; peduncles 4–28 mm long; bracts and bracteoles linear-lanceolate, 1–3 mm long. Perianth yellowish green, leathery; hermaphrodite flowers: tube 0.5–0.6 mm long, obscured inside by disk, lobes 3(–4), spreading, ovate-deltate, 1.5–2x1.8–2.2 mm, tips slightly hooded; male flowers similar. Stamens 3(–4); filaments 0.5–0.7 mm long; anthers 0.5 mm long. Ovary 2–2.8 mm long, ovules 3(–4) in hermaphrodite flowers, ovules and placenta aborted in male flowers; style 0.8–1 mm long, thick, cylindric; stigma in hermaphrodite flowers normally 4- rarely 3-lobed, lobes ellipsoid, prominent; in male flowers both style and stigma aborted or rudimentary. Fruit ellipsoid, 5–6.5 mm in diameter when dry, epicarp thin, fleshy, red when ripe. Fig. 5 (page 24).

Notes
Great variation in leaf size and shape has elicited a considerable synonymy. The above list is not exhaustive. It has at times been included in O. compressa (Berg.) A.DC., but that species has the leaves generally opposite, the flowers are all hermaphrodite, the floral parts are generally in fours and the style is much shorter, as elucidated by Stauffer, loc. cit. (1961), and Hilliard in Edinb. J. Bot. 51: 391–392 (1994).  The wood has a fuel value as a substitute for sandalwood according to I.T.U., ed. 2: 373 (1952) & K.T.S.: 500 (1961).
