Macrozamia riedlei, commonly known as zamia or zamia palm, is a species of plant in the Zamiaceae family. The Noongar names for the plant are baian, djiriji, koondagoor and quinning.[2]

Found on lateritic soils and in Jarrah forests, it is endemic to Western Australia. The nuts from this plant have been successfully used as food by Indigenous Australians after proper processing - however eaten raw by European explorers incurred poisoning:-

Reported cases of poisoning from this cycad are perhaps the earliest for any local plant. Macrozamia riedlei is mentioned as causing sickness in men eating the seeds by Vlaming in 1697, La Perouse in 1788, Flinders in 1801, and Sir George Grey in 1839. (Gardner and Bennetts p.5.)
