Narrow, brown, brittle stripes usually visible in the blaze.
Numerous oil dots visible with a lens if not visible to the naked eye. Leaf blades about 4-10 x 1-5 cm. Midrib depressed on the upper surface. Petiole grooved on the upper surface. Lateral veins inconspicuous.
Bracts caducous, absent at anthesis. Calyx tube (hypanthium) gradually tapering into the pedicel, calyx tube (hypanthium) + pedicel about 3-4.5 mm long, calyx tube (hypanthium) about 1.5-3 mm diam., calyx lobes triangular, about 0.2-0.3 mm long. Petals irregular in shape, tending to be rounded or truncate at the base and acuminate at the apex, about 1.5 x 1 mm, oil dots often difficult to discern, generally fewer than ten per petal. Staminal filaments variable, longer filaments about 1.3-2.2 mm long, anthers wider than long, about 0.3 x 0.4 mm, gland absent or small and inconspicuous. Ovules about 6-8 per locule, placentas apical, ovules pendulous. Style about 0.7-1.5 mm long, not exceeding the calyx tube (hypanthium).
Fruits globular, attaining about 12-15 mm diam., calyx lobes persistent, inconspicuous, about 0.2-0.3 mm long. Seed solitary, about 6-7 mm diam., testa adhering to the succulent pericarp, but easily separating from the uniformly textured cotyledons. Radicle central or basal, cotyledonary stipules present.
