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.

来自北美西北地区的古民族植物群落通常会产生地上植物地下器官，但这些碳化的残留物很难确定物种或属水平。我们检查了11种（8属）最人种学上最西北的地理植物食品的宏观和微观形态植物特征，重点研究了来自芦笋和莉利亚莱斯的鳞茎。在本文中，我们讨论了可能影响考古材料的人种学实践，并为新鲜和碳化的植物提供了数字化的摄影和定量参考。我们确定人行道表皮细胞是鉴定古植物群中鳞茎的最诊断标准。这些鉴定标准为研究人员提供了比较材料，以解决植物的使用问题，
