Pink, the garden name for several species of Diantlms, a large genus of Caryophyllacese. They are mostly natives of the temperate regions of the Old World, and are distinguished by having two or more bracts at the base of a cylindric calyx-tube, and two styles. The ovary, though with "free central" placentation (q.v.), exhibits rudiments of septa between its constituent carpels. Their foliage is generally linear and often glaucous; their flowers white or some shade of pink or red, often dotted or lined with white, or with a ring of another shade, and with fringed margins to the petals.
