Growing Regions

The range of Allegheny chinkapin extends from New Jersey and Pennsylvania south to Florida and west to eastern Texas, eastern Oklahoma, and southern Ohio [4,16]. Ozark chinkapin is limited to the Ozark highlands of Arkansas, Missouri, and Oklahoma, and has been extirpated from most of Alabama by chestnut blight [10].

     

General Information

The currently accepted scientific name for Allegheny chinkapin is Castanea pumila (L.) Mill. (Fagaceae) [4,8,16]. This highly variable species has a number of infrataxa which have sometimes been given separate species status [4,10,11,32,33]. Johnson [10,11] and Tucker [33] agree that most, and probably all, chinkapins should be treated as a single species. Currently accepted varieties include the following: Castanea pumila var. pumila C. pumila var. ashei Sudw. [13,22] coastal chinkapin C. pumila var. ozarkensis (Ashe) Tucker [10,13,34] Ozark chinkapin Allegheny chinkapin and American chestnut (Castanea dentata) hybridize to form C. xneglecta Dode [16].

Allegheny chinkapin is locally abundant as a low, clonal shrub on longleaf pine (Pinus palustris)-scrub oak (Quercus spp.) sand ridges and hills that are burned frequently, and in open stands of planted pine on ridges and hills. It is less frequent in sand pine (P. clausa)-oak scrub [8]. Ozark chinkapin is often associated with chinkapin oak (Quercus muehlenbergii) in white oak (Q. alba)-black oak (Q. velutina)-northern red oak (Q. rubra) cover types [26].
