Editing Chestnut (section)

=== Species ===
Chestnuts belong to the [[Family (biology)|family]] [[Fagaceae]], which also includes [[oak]]s and [[beech]]es. The four main species groups are commonly known as American,<ref name=laren58>[http://www.chestnutsaustralia.com.au/content/view/24/58/ Industry information] {{webarchive|url=https://web.archive.org/web/20080808092004/http://www.chestnutsaustralia.com.au/content/view/24/58/ |date=2008-08-08 }} by David McLaren. From ''The Chestnut Growers Information Book'', Chestnut Australia Inc.</ref> European, Chinese, and Japanese chestnuts.

The taxonomy of the American chestnuts is not completely resolved, particularly between the chinkapins ([[Castanea ozarkensis]] and [[Castanea pumila]]), which are sometimes considered to be the same species. Genetics have indicated the California native "golden chinkapin" ([[Chrysolepis chrysophylla]]) is worthy of inclusion in a different genus along with a species from Coastal China. There is also another chestnut, ''[[Castanea alabamensis]]'', which may be its own species.<ref>{{cite journal|doi=10.1600/036364421X16370109698524|title=Genome-Wide Sequence-Based Genotyping Supports a Nonhybrid Origin of ''Castanea alabamensis'' |year=2021 |last1=Perkins |first1=M.
