Species[citation needed]

Pteroceltis is a genus of small trees in the family Cannabaceae and containing the living species Pteroceltis tatarinowii.[1] The genus is now restricted to an endemic range in China and Mongolia. The genus has a fossil record which includes species described from Korea, Japan, Germany, and the United States.[2]

The fossil record includes one described species from North America, † from the Middle Eocene Cockfield Formation in Tennessee, while an undescribed species is known from the Klondike Mountain Formation of Washington. One late Oligocene species † has been described from strata near Rott, Germany. The largest diversity of fossils are from Asia, with † from the Miocene in China, the of Japan preserved †, and both † plus † known from the Miocene in North Korea.[2][3]
