Translationswitch hazel
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 roddivining rod
or dowser,
stick used in searching for underground water or minerals. This form of divination is still in common use in many parts of the world. The instrument is typically a forked twig.
