Description
Stem
Seldom exceeding 30 cm dbh.
Leaves
Leaf blades about 6.3-10.8 x 2.9-5.2 cm, petioles about 0.4-0.9 cm long. Oil dots numerous. Midrib depressed on the upper surface at least towards the base of the leaf blade. Leaf blade much paler on the underside. Veins not very obvious on either the upper or lower surfaces.
Flowers
Bracts often present at anthesis. Calyx tube (hypanthium) + pedicel about 5-9 mm long, calyx tube (hypanthium) about 3-5 mm diam., calyx lobes +/- uniform, triangular to narrowly triangular, about 4-5 mm long. Petals spathulate, lanceolate or +/- orbicular, about 6-7 x 2-3 mm when spathulate, slightly wider when orbicular, oil dots visible, about 30-50 per petal. Outer staminal filaments about 15-25 mm long, anthers about 1 x 0.7 mm, gland terminal, reasonably conspicuous. Ovules 10-18 per locule, placentas central, ovules radiating, ascending. Style about 18-30 mm, approximating the stamens.
Fruit
Fruits globular or depressed globular, about 10-16 x 18-21 mm, calyx lobes persistent, about 4-5 mm long, pericarp fleshy, slightly fibrous. Seeds solitary, about 10 x 12 mm along the longer diameter, testa adhering to the pericarp but free from the smooth surface of the uniformly textured, shortly petiolate cotyledons. Radicle basal, cotyledonary stipules present but not obvious.
Seedlings
Cataphylls about 3-5 pairs. At the tenth leaf stage: leaf blade obovate, apex acuminate, base attenuate, glabrous; oil dots easily visible with a lens. Seed germination time 36 to 70 days.
