CHENOPODIUM, in botany, a genus of the pentandria digynia class. The calix consists of five leaves; it has no corolla; and there is but one lenticular seed. There are 18 species, 13 of which are natives of Britain, viz. the bonus henricus, common English mercury, or all-good; the urbicum, or upright blite; the rubrum, or sharp leaved goose foot; the murale, common goose-foot, or sow-bane; the hybridum, or maple-leaved blite; the album, or common orache; the viride, or green blite; the serotinum, or late-flowered blite; the glaucum, or oak-leaved blite; the vulvaria, or stinking orache; the polyspermum, round-leaved blite, or all-feed; the maritimum, sea blite, or white glass-wort; and the fruticosum, shrub stone-crop, or glass-wort. The leaves of the vulvaria, or stinking orache, are said to be an excellent anti-hysteric.
