Approximately 50,000 carbonized fruits of the species Chenopodium berlandieri recovered from Russell Cave, Alabama, and dating to 1975 ± 55 before the present, exhibit a set of interrelated morphological characteristics reflecting domestication (thin testa, truncate margin, rectanguloid fruit cross section, ligulate cotyledons, and increased internal fruit volume). These morphological characteristics establish the presence of a domestic variety of Chenopodium in the eastern United States by 2000 years ago.
