BELLIS, or DAISY, in botany, a genus of the syngenesia polygamia superflua class. The receptacle of the bellis is naked and conical; it has no pappus; the calix is hemispherical, with squamæ of an equal size; and the seeds are oval. There are two species; viz. the hortensis, a native of several parts of Europe; and the perennis, or common daisy, a native of Britain. The leaves of the perennis have a subacid taste, and are recommended as vulneraries, and in asthmas and hectic fevers.
