The genus LiquidambarHamamelidaceae is one of a number of taxa associated with the Daijimatype floras of late Early to early Middle Miocene age, which also include many warm-temperate to subtropical elements. However, Liquidambar is very rare or absent in the Aniai-type floras of the early Early Miocene. We describe fossil leaves, fruits and pollen of this genus found in the Lower Miocene Nakamura Formation in the southern part of Gifu Prefecture. The flora of the Nakamura Formation Hiyoshi flora shows features common to those of the conformably underlying Hachiya Formation earliest Early Miocene but differs from the unconformably overlying Hiramaki Formation late Early Miocene in the same region. This fact combined with the occurrence of Liquidambar in the Hiyoshi flora, associated with warm-temperate elements such as Pseudolarix, Castanea, Celtis and Lindera, clearly supports one of two former views: the flora is of a southern type within the Aniai-type floras.CThe Geological Society of Japan 2007 542
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
