| "Emergent trees up to 62 m tall and 197 cm dbh. Stem with resin. Stipules up to ca. 7 mm long. Leaves alternate, simple, penni-veined, secondary venation very close together. Flowers ca. 5 mm in diameter, white, placed in short panicles. Fruits ca. 35 mm long, yellow-red-purplish, with five wings originating from the calyx base up to ca. 50 mm long, wind dispersed." | "Emergent trees up to 62 m tall and 197 cm dbh. Stem with resin.

| Main components of the essential oil, collected by steam distillation of the exudates from D.aromatica, were β-caryophyllene (21-37%), α-caryophyllene (8-16%), α-pinene (10-36%), terpinen-4-ol (5-10%) and α-terpineol (3-7%). Borneol was detected in the essential oil of D. aromatica at 0.74%. This finding was different from other studies. Huang and Lu reviewed that the exudates or essential oil of D. aromatica comprised of borneol, α-caryophyllene, β-elemene, β-caryophyllene, asiatic acid, dryobalanone, erythrodiol and hydroxy-dammarenone II. \\ | Main components of the essential oil, collected by steam distillation of the exudates from D.aromatica, were β-caryophyllene (21-37%), α-caryophyllene (8-16%), α-pinene (10-36%), terpinen-4-ol (5-10%) and α-terpineol (3-7%).
