Ecological, ethnobotanical, and nutritional aspects of Yellow Glacier Lily, Erythronium grandiflorum Pursh (Liliaceae), in Western Canada
This research examined a single bulb-bearing edible plant species, yellow glacier lily (Erythronium grandiflorum ). Three main approaches to the research were taken: 1) an ecological study, to determine the general habitat requirements of the species in western Canada, and to investigate the nature...
