The murnong or yam daisy is any of the plants Microseris walteri, Microseris lanceolata and Microseris scapigera, which are an important food source for many Aboriginal peoples in southern parts of Australia. The roots of the murnong plants were consumed in large quantities by Aboriginal people in the colony of Victoria until the 1840s, when European colonists began using the murnong crop lands for sheep farming.
