Chloranthus elatior Link Enum. Hort. Berol. Alt. 1: 140 (1821)

Named meaning 'highest', perhaps in reference to another species in the genus?

Remarks
Some floras follow the name Chloranthus erectus (Buch.-Ham.) Verdcourt because B. Verdcourt (Kew Bull. 40: 217. 1985), rejected the name Chloranthus elatior R. Brown ex Sims as a nomen nudum, and C. elatior Link as too poorly known to be usable; the latter was based on a sterile cultivated plant and the type was destroyed in Berlin.

Uses
Leaves and roots are used as aphrodesiac, especially for women. In India the juice of the boiled branches is used as a contraceptive, and the root and the bark acts as a antispasmodic during childbirth. The leaf extract is considered a cure for venereal diseases. The plant is also used to treat fever, and pain killer.

From India and southern Himalayas to southern China, Indochina, Philippines, Indonesia to New Guinea.
