Engelhardia is a genus of seven species of trees in the family Juglandaceae, native to southeast Asia from northern India east to Taiwan, Indonesia and the Philippines. The genus name is commonly misspelled "Engelhardtia", a "correction" made by the original author Blume in 1829 and persistent until today, as it was thus entered in the Index Kewensis; the original spelling is Engelhardia.
Fossil record
Engelhardia pollen has been found in deposits of Miocene Age in Denmark.[1] Engelhardia orsbergensis leaf fossils have been recovered from rhyodacite tuff of Lower Miocene age in Southern Slovakia near the town of Lučenec.[2] Fossils of this species has also been recovered from late Miocene strata in Iceland, in addition to Engelhardia macroptera, both extinct species.[3]
