Langeria
''Langeria'' is an extinct genus of flowering plant in the family Hamamelidaceae, commonly known as the witch-hazel family, containing the solitary species ''Langeria magnifica''. The species is known from fossil leaves found in the early Eocene deposits of northern Washington State, United States and similar aged formations in British Columbia, Canada. ==History and classification== ''Langeria magnifica'' has been identified from a series of locations ranging from the Klondike Mountain Formation near Republic, Washington north. At least three locations in British Columbia have ''Langeria'' fossils, including the Quilchena locality near Merritt, the McAbee Fossil Beds near Kamloops, and the Joseph Creek site near Chu Chua. Generally speaking, the age for the locations is Early Eocene, with the sites that have current Uranium-lead or Argon–argon radiometric dates being of Ypresian age, while the undated sites and sites with less current dating being possibly slightly younger and Lutetian in age. ''Langeria magnifica'' was described from a series of type specimens, the actual holotype specimen being UW 39713, in the paleobotanical collections of Burke Museum, University of Washington, and its counterpart being UCMP 9273, currently preserved in the University of California Museum of Paleontology. An additional eight leaves from both the Burke Museum and UC Museum of Paleontology were designated paratypes specimens. Working from those specimens, collected in the Republic, Washington area in the early 1980s, the fossils were studied by Jack A. Wolfe of the University of California and Wesley C. Wehr of the Burke Museum.〔 They published their 1987 type description for the genus and species in a United States Geological Survey monograph on the North Eastern Washington dicot fossils. The genus name ''Langeria'' is a matronym honoring the American philosopher of mind, Susanne K. Langer, who influenced the analysis and organization of scientific data.〔 The specific epithet ''magnifica'' would imply "magnificently large". Wolfe and Wehr note that the extinct species ''"Fortunearia" weedi'' is distinctly similar to ''Langeria magnifica'' and might turn out to be congeneric.〔
