cornel(kôr`nəl), shrub or tree of the genus Cornus, chiefly of north temperate and tropical mountain regions, characteristically having an inconspicuous flower surrounded by large, showy bracts which are often mistaken for petals. This trait is evident in the flowering dogwood (C. florida) of E North America, with white or pink bracts, and the very similar Pacific dogwood (C. nuttallii) of the West. Dogwood anthracnose, a fungal disease, has killed many wild woodland dogwoods since the 1980s. Both species are cultivated as ornamentals. Their bark, rich in tannin, has been used medicinally (as is that of the other species of Cornus), for example, as a quininequinine
, white crystalline alkaloid with a bitter taste. Before the development of more effective synthetic drugs such as quinacrine, chloroquine, and primaquine, quinine was the specific agent in the treatment of malaria.

The fruits of some species are edible, e.g., those of the Old World cornelian cherry (C. mas), used also for preserves and the French liqueur vin de cornouille. The bunchberry, or dwarf cornel (C. canadensis), is a low herbaceous wildflower of North America. Dogwoods are classified in the division MagnoliophytaMagnoliophyta
, division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. The angiosperms have leaves, stems, and roots, and vascular, or conducting, tissue (xylem and phloem).

shrubs and trees of several species. Swida sanguinea is usually called dogwood; it is widespread in western and central regions of the European USSR and in middle and southern Europe; more rarely, S. australis, which grows in the Crimea, the Caucasus, and Asia Minor, is called dogwood. They are shrubs or low trees of the family Cornaceae, having purple shoots, white flowers and corymbiform inflorescences without spathes, and opposite, simple leaves, pale-green underneath. The fruits are juicy and spherical, blue-black or black. Both species are widely grown as ornamentals. Sometimes the wild service tree is called dogwood.
(Cornus), a genus of trees and shrubs of the family Cornaceae. The leaves are simple, entire, and opposite. The small bisexual flowers are gathered in umbellate clusters. The fruits are fleshy red drupes on stalks. Four species are found in central and southern Europe, Asia Minor, central China, Japan, and North America (California). The Soviet Union has one species, the cornelian cherry (Cornus mas). It grows in the underbrush and thickets at the edges of leafy forests in the southwestern European USSR, the Crimea, and the Caucasus. Its fruits are eaten fresh and used in preserves and compotes. The hard heavy wood is used in the manufacture of various items. Dogwood trees contain tannins, and are nectar-bearing.
