CHEIRANTHUS, in botany, a genus of the tetradynamia filiquosa class. The germen has teeth-like glands on each side; the calix is close, and consists of two small leaves, gibbous at the base; and the seeds are plain. There are thirteen species, only two of which are natives of Britain, viz. the cheiri, wall-flower, or wild cheir; and the tricuspidatus, or sea stock-gilly-flower. The leaves of the wall-flower are said to be cordial, anodyne, aperient, and emmenagogue; but are wholly neglected in practice.
