Viburnum is a genus of about 150175 species of shrubs or (in a few species) small trees in the moschatel family, Adoxaceae. Its current classification is based on molecular phylogeny. It was previously included in the family Caprifoliaceae. The member species are native throughout the temperate Northern Hemisphere, with a few species extending into tropical montane regions in South America and southeast Asia. In Africa, the genus is confined to the Atlas Mountains. The generic name originated in Latin, where it referred to V. lantana. The leaves are opposite, simple, and entire, toothed or lobed; cool temperate species are deciduous, while most of the warm temperate species are evergreen. Some species are densely hairy on the shoots and leaves, with star-shaped hairs. The flowers are produced in corymbs 515 cm across, each flower white to cream or pink, small, 35 mm across, with five petals, strongly fragrant in some species.
