Distylium (winter-hazel) is a genus of about 18 species of evergreen shrubs and trees in the witch hazel family, Hamamelidaceae, native to eastern and southeastern Asia.
Fossil record
Researchers have recognized Distylium fossil pollen among the middle Miocene Sarmatian palynoflora from the Lavanttal Basin of Austria. The sediment containing the fossil pollen had accumulated in a lowland wetland environment with various vegetation units of mixed evergreen/deciduous broadleaved/conifer forests surrounding the wetland basin. Key relatives of the fossil taxa found with Distylium are presently confined to humid warm temperate environments, suggesting a subtropical climate during the middle Miocene in Austria.[1]
