Гамамелисовые - Hamamelidaceae 4/15/17—5/1/23
Hamamelidaceae, commonly referred to as the witch-hazel family, is a family of flowering plants in the order Saxifragales. The clade consists of shrubs and small trees positioned within the woody clade of the core Saxifragales. The earlier Cronquist system recognized Hamamelidaceae in the Hamamelidales order.
The Hamamelidaceae were widely distributed in the Northern Hemisphere during the Upper Cretaceous and early Tertiary. Quaternary glaciation across the Northern Hemisphere caused the extinction of numerous species and the restricted distribution of others. Hamamelidaceae were completely obliterated from Europe along with numerous other genera of plants that were unable to escape the ice sheets due to geography (the Mediterranean Sea and Alps forming barriers that did not exist in North America and Asia)
The largest subfamily, the Hamamelidoideae, is now distributed in North America and western and eastern Asia. The Hamamelidoideae subtribe Dicoryphinae is now restricted to the African (including Madagascar and Comores) and Australian continents. Disanthoideae and Rhodoleioideae are now restricted to southern China and the Caucasus region. Mytilarioideae is restricted to eastern Asia. Altingioideae is now restricted to eastern Asia and western Asia and North America between central Mexico and Belize.
