'''''Langeria''''' is an [extinct](/source/extinct) genus of [flowering plant](/source/flowering_plant)s in the family [Platanaceae](/source/Platanaceae) containing the solitary species '''''Langeria magnifica'''''. ''Langeria'' is known from [fossil](/source/fossil) leaves found in the early [Eocene](/source/Eocene) deposits of northern [Washington state](/source/Washington_(state)), United States and similar aged formations in [British Columbia](/source/British_Columbia), Canada.[{{cite journal |last1=Dillhoff |first1=R.M. |last2=Leopold |first2=E.B. |last3=Manchester |first3=S.R. |year=2005 |title=The McAbee flora of British Columbia and its relations to the Early-Middle Eocene Okanagan Highlands flora of the Pacific Northwest |journal=Canadian Journal of Earth Sciences |volume=42 |issue=2 |pages=151–166 |doi=10.1139/e04-084|bibcode=2005CaJES..42..151D }}]
==Distribution==
''Langeria magnifica'' has been identified from a series of locations ranging from the [Klondike Mountain Formation](/source/Klondike_Mountain_Formation) near [Republic, Washington](/source/Republic%2C_Washington)[{{cite journal |last1=Wolfe |first1=J.A. |last2= Wehr |first2=W.C. |year=1987 |title=Middle Eocene dicotyledonous plants from Republic, northeastern Washington |journal= United States Geological Survey Bulletin |volume=1597 |pages=1–25}}] north. At least three locations in British Columbia have ''Langeria'' fossils, including the [Coldwater Beds](/source/Coldwater_Beds) Quilchena locality near [Merritt](/source/Merritt%2C_British_Columbia), the [Tranquille Formation](/source/Tranquille_Formation)s [McAbee Fossil Beds](/source/McAbee_Fossil_Beds) near [Kamloops](/source/Kamloops%2C_British_Columbia), and the [Chu Chua Formation](/source/Chu_Chua_Formation)s Joseph Creek site near [Chu Chua](/source/Chu_Chua%2C_British_Columbia). Generally speaking, the age for the locations is [Early Eocene](/source/Early_Eocene), with the sites that have current [uranium–lead](/source/uranium%E2%80%93lead_dating) or [argon–argon](/source/argon%E2%80%93argon_dating) radiometric dates being of [Ypresian](/source/Ypresian) age, while the undated sites and sites with less current dating being possibly slightly younger and [Lutetian](/source/Lutetian) in age.[{{cite journal |last1=Greenwood |first1=D.R. |last2=Archibald |first2=S.B. |last3=Mathewes |first3=R.W |last4=Moss |first4=P.T. |year=2005 |title=Fossil biotas from the Okanagan Highlands, southern British Columbia and northeastern Washington State: climates and ecosystems across an Eocene landscape |journal=Canadian Journal of Earth Sciences |volume=42 |issue=2 |pages=167–185 |doi=10.1139/E04-100|doi-broken-date=18 November 2025 |bibcode=2005CaJES..42..167G }}]
==History and classification==
''Langeria magnifica'' was described from a series of [type specimens](/source/type_specimens), the actual [holotype](/source/holotype) specimen being UW 39713, in the [paleobotanical](/source/paleobotany) collections of [Burke Museum](/source/Burke_Museum), University of Washington, and its [counterpart](/source/Compression_fossil) being UCMP 9273, currently preserved in the [University of California Museum of Paleontology](/source/University_of_California_Museum_of_Paleontology). An additional eight leaves from both the Burke Museum and UC Museum of Paleontology were designated [paratype](/source/paratype)s specimens. Working from those specimens, collected in the [Republic, Washington](/source/Republic%2C_Washington) area in the early 1980s, the fossils were studied by [Jack A. Wolfe](/source/Jack_A._Wolfe) of the [University of California](/source/University_of_California) and [Wesley C. Wehr](/source/Wesley_C._Wehr) of the Burke Museum.[{{cite book |url=https://books.google.com/books?id=Jf1bbevG5TMC&pg=PA243|title=Life in Stone: A Natural History of British Columbia's Fossils|first=Rolf |last=Ludvigsen|year=2011|publisher=UBC Press|isbn=978-0774841511|page=243}}] by Wolfe and Wehr. This placement was later questioned and the genus was subsequently reclassified by Indah Huegele and Steven Manchester (2022) as a member of the [plane tree](/source/plane_tree) family [Platanaceae](/source/Platanaceae).[{{cite journal |last1=Huegele |first1=I.

==Description==
The simple leaves of ''Langeria magnifica'' are generally [pinnate](/source/Pinnation) in venation with an overall ovate to elliptical shape and an apex that is notably pointed. The [petiole](/source/Petiole_(botany)) can reach lengths of up to {{convert|6|cm|in|abbr=on}} The margin of the leaf has evenly spaced, distinct hook-shaped teeth with rounded [sinuses](/source/Sinus_(botany)) separating them.
