witch hazel, common name for some members of the Hamamelidaceae, a family of trees and shrubs found mostly in Asia. The family includes the large genus (Corylopsis) of winter hazels, and the witch hazels (genus Hamamelis), sweet gums (Liquidambar), and witch elders (Fothergilla), the latter three genera represented by species in E North America as well as in Asia. The American witch hazel (H. virginiana) is a fall-blooming shrub or small tree found E of the Rockies. Its ripening fruits discharge their seeds by a characteristic explosive action, often shooting them several feet. The plant seems to have been named for the resemblance of its leaves to those of the hazel, and the witch hazel branch, like that of the hazel, has been used as a divining rod. The name "witch hazel" is applied also to an astringent liniment obtained from the leaves and bark of the plant. The sweet gums are characterized by their star-shaped leaves, their unusually brilliant and varied autumn coloring, and their round fruits with hornlike projections. The hard wood is used for cabinetmaking and for various building purposes. The bark, especially that of Asian species, is a source of storax or styrax, a fragrant balsam used in expectorants and perfumes and sometimes in chewing gum. Witch hazel is classified in the division Magnoliophyta, class Magnoliopsida, order Hamamelidales, family Hamamelidaceae.

hazel, any plant of the genus Corylus of the family Betulaceae (birch family), shrubs or small trees with foliage similar to the related alders. They are often cultivated for ornament and for the edible nuts. Hazels are also called filberts, although the latter is more strictly a name for European kinds (C. maxima, C. avellena, and their varieties, e.g., the cobnut) that are cultivated, chiefly in Europe, for the filbert of commerce. Nuts of the American hazel (C. americana) are often gathered but seldom sold. Winter hazel and witch hazel are not related to hazel. Hazel is classified in the division Magnoliophyta, class Magnoliopsida, order Fagales, family Betulaceae.

Hazel Park, city (1990 pop. 20,051), Oakland co., SE Mich., a suburb of Detroit; inc. 1942. Hazel Park has varied light manufacturing industries and a racetrack. Most of the early settlers were German. Ottawa chief Pontiac made his headquarters in Hazel Park.

Family Hamamelidaceae, comprising 23 genera of shrubs and trees, native to tropical and warm temperate regions. The six species of the genus Hamamelis include such ornamentals as witch hazel, winter hazel, and Fothergilla, which are outstanding for their early flowering and fall leaf colour. Members of the family are characterized by simple leaves and by flowers with four or five petals and sepals each. American, or common, witch hazel (H. virginiana) flowers in fall and retains yellow, cuplike calyxes (collections of sepals) through the winter. The common name refers to the forked twigs that were sometimes used for water-witching, or dowsing to locate underground water. The fragrant liniment witch hazel is made from the dried leaves and sometimes from twigs and bark. Brilliant autumn leaf colour is an outstanding trait of ironwood (Parrotia persica). Another genus, Altingia, has seven species, all Asian and all valued for their timber. A. excelsa is one of the largest trees of the Asian tropics, sometimes reaching a height of 82 ft (25 m).

or hazel(nut)

Any of about 15 species of deciduous trees and shrubs that make up the genus Corylus, in the birch family, native to the northern temperate zone; also, the edible nuts they produce. Choice nuts are produced by two Eurasian trees, the European filbert (C. avellana) and the giant filbert (C. maxima), and by hybrids of these species. Some varieties are valuable hedgerow and ornamental trees. An oil from C. avellana is used in food products, perfumes, and soaps; the tree yields a soft, reddish-white timber that is useful for small articles such as tool handles and walking sticks.
