Seasons of Change: Using Seasonal Morphological Changes in Brodiaea Corms to Determine Season of Harvest from Archaeobotanical Remains

Abstract

AbstractI present archaeobotanical evidence for intensive and long-term harvesting of edible geophytes in the Brodiaea complex, most likely blue dicks (Dichelostemma capitatum), during multiple seasons on California’s Santa Cruz Island. Ethnographic data indicate that Brodiaea corms were an important food source throughout prehistoric California, usually harvested in the late spring–early summer, after flowering. However, at least two ethnographic sources may suggest multiple seasons of harvest, an idea supported by careful examination of seasonal morphological changes in modern and ancient Brodiaea corms. Archaeobotanical identification of features associated with these morphological changes allows inferences about the specific seasons in which Brodiaea corms were harvested, a conclusion that has the potential to provide higher resolution seasonality data for geophyte remains recovered in western North America and other areas around the world.
