Not until after the 1930’s-1940’s (in some books as late as the 1960’s) does the term “Ozark chinquapin” (Castanea ozarkensis) become commonly referred to in tree books. Prior to these dates tree book authors lumped them together with the Allegheny and made special notations about incredible large Allegheny chinquapins that grew in Arkansas and in Southern Missouri. 

In his book, A Natural History of Trees, Donald Culross Peattie writes, “Nuts were sometimes to be seen in the markets of towns in our South. In that region it is useless as a timber, being indeed little more than a shrub, but west of the Mississippi it seems to be inspired by a new ambition and reaches heights up to 50 feet, with a diameter of two or three feet.”  -page 191, copyright 1948-1950
