CHLORANTHA'CEÆ, a natural order of exogenous plants, closely allied to the peppers; herbaceous and half-shrubby plants, with jointed stems, opposite simple leaves, and minute stipules between them. The flowers are in terminal spikes, and are destitute of calyx and corolla, but have each a small scale or bract. The stamens are lateral ; either only one or few, and partly cohering. The ovary is one-celled, immediately crowned with the stigma ; the ovule is pendulous ; the fruit a drupe or one-seeded berry; the embryo naked, not in a fleshy sac as in the peppers.---The number of known species is small : all of them are tropical, or natives of China and Japan.
