Abstract
Paleoethnobotanical assemblages from the Northwestern region of North America often yield geophyte subterranean organs, but these carbonized remains are difficult to identify to species or genus level. We examine 11 species (8 genera) of the most ethnographically prevalent Northwest geophyte foods for macro- and micro-morphologic geophyte features, with a focus on bulbs from the Asparagales and Liliales orders. In this contribution, we discuss ethnographic practices which may affect archaeological material and provide digital photographic and quantitative references for both fresh and carbonized geophytes. We determine that pavement epidermal cells are the most diagnostic criteria for identifying bulbs in paleoethnobotanical assemblages. These identification standards provide researchers with comparative material to address questions of plant use, preparation, and stewardship across the greater Northwest Coast and Columbia-Fraser Plateau cultural and geographic regions.
