Discussion
Castanea pumila was thought to be extirpated from Long Island, New York, but it was recently recollected in Suffolk County.
Numerous names have been applied to populations included here under Castanea pumila (see also C. ozarkensis). In general, the pattern of morphologic variation suggests three forms that have some geographic and ecologic continuity, but among which sufficient clinal variation occurs to prevent easy recognition. Plants of higher elevation and northern populations tend to be trees or large shrubs with densely tomentose vestiture of the abaxial leaf surface, while southern coastal populations typically have flat-stellate vestiture, often very sparse or even glabrate (e.g., C. floridana). These coastal populations may be separated into forms that are trees or large shrubs with leaves sparsely to not at all glandular versus low rhizomatous shrubs with prominent globose glands on twigs and leaves (centered in northern Florida and adjacent Georgia). The latter form is probably the same as C. alnifolia.
Various preparations of the leaves of Castanea alnifolia were used by Native Americans medicinally to relieve headaches and as a wash for chills and cold sweats; preparations from unspecified parts of the plants were used to treat fever blisters (D. E. Moerman 1986).
