Inflorescence terminal, branched, 7--10 cm; rachis glabrous. Flowers solitary, rarely paired; pedicel ca. 10 mm, articulate above middle.

Chinese plants were treated in FRPS as Dracaena gracilis which is an illegitimate name (a later homonym). J. J. Bos (pers. comm.) notes that the type specimen of D. elliptica var. gracilis, from Penang, Malaysia, differs from typical D. elliptica only in having somewhat narrower leaves. He believes that the plant should be treated under D. elliptica but does not support any infraspecific status for it.
