Map 1, from the Biota of North America Program (BONAP), shows the distribution of Physalis longifolia. Yellow counties are where specific locations of Physalis longifolia are known accurately to within a few meters. Light green counties are where plants are known to occur in the county. Green locations are where the plants are known for the state or provinces.
Map 2, from the USDA Natural Resources Conservation Service, shows sites of documented use of Physalis species in North America. The range of all Physalis species is in green. Tribes who used these species for food or medicine are listed and numbered; archeological sites where Physalis seeds have been found are indicated with stars. These sites and areas are referenced in a forthcoming paper on the Native American ethnobotany (cultural use) of Physalis longifolia and related species.
Map 3 shows locations where Physalis longifolia voucher specimens are located in herbaria and botanical museums.
