Strong aroma to crushed foliage. Leaves opposite and decussate, unifoliolate with articulation at junction of lamina and petiole; petiole 0.3-2.5 cm long; appearing shallowly grooved above in dry material, with slight swelling at junction. Leaf blade narrowly elliptic to elliptic, occasionally obovate, about 2.2-10 cm long, 0.9-4.5 cm wide, apex obtuse, acute, and shallowly retuse. Venation with 10-12 main lateral veins on each side of the midrib. Oil dots visible with hand lens.
Inflorescence cymose, axillary, appearing to arise between leaf nodes when leaves fall off, to 9 cm long. Flowers 7.5-8.5 mm long, petals hooded on inner surface at apex, cream. Stamens more or less alternately unequal in length, subequal at anthesis, sometimes distinctly unequal in young buds. Ovary with septicidal fissures (with crevices in line with septa) at least in distal or upper half. Disk yellow.
Fruits broadly ovate to elliptic in outline (side view), strongly 4 lobed to winged, about 12 mm long and 10 mm wide, rose-red to pink, becoming yellowish at maturity, drying reddish brown. Septicidal fissures present, seen as well developed longitudinal crevices between locules of fruit. Seeds dark reddish brown, about 5 mm long.
Cotyledons about 7 mm long, margins entire. First and second pairs of leaves unifoliolate.
