Quercus prinoides
''Quercus prinoides'', commonly known as dwarf chinkapin oak, dwarf chinquapin oak, dwarf chestnut oak or scrub chestnut oak, is a shrubby, clone-forming oak native to eastern and central North America, ranging from New Hampshire to the Carolinian forest zone of southern Ontario to eastern Nebraska, south to Georgia, Alabama, Louisiana, and Oklahoma. It has a virtually disjunct (discontinuous) distribution, fairly common in New England and in the Appalachian Mountains, and also in the eastern Great Plains but rare in the Ohio Valley in between.〔(Biota of North America Program 2014 county distribution map )〕
==Classification and nomenclature==
''Quercus prinoides'' was named and described by the German botanist Karl (Carl) Ludwig Willdenow in 1801,〔(【引用サイトリンク】url=http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=233501075 )〕 in a German journal article by the German-American Pennsylvania botanist Gotthilf Heinrich Ernst Muhlenberg.〔Muhlenberg, Gotthilf Heinrich Ernest. 1801. Der Gesellsschaft Naturforschender Freunde zu Berlin, neue Schriften 3: 397〕 The epithet ''prinoides'' refers to its resemblance to ''Quercus prinus'', the chestnut oak.
However, this shrubby oak, now generally accepted as a distinct species, is more closely related to chinkapin oak (''Quercus muhlenbergii'') than to chestnut oak.〔 These two kinds of oak have sometimes been considered to be conspecific (belonging to the same species), in which case the earlier-published name ''Q. prinoides'' has priority, with the larger chinkapin oak then usually classified as ''Quercus prinoides'' var. ''acuminata'', and the shrubby form as ''Q. prinoides'' var. ''prinoides''.
