All 3 members of the Stangeriaceae have underground stems and throw up leaves from below ground. In Bowenia these leaves are bi-pinnate and really rather fern like (in the same greenhouse as this specimen I spent quite a while trying to work out if a fern was the other Bowenia species)
Bowenia serrulata is, due to its fernlike leaves, confusingly known as the Byfield Fern and is found only in Queensland, Australia. It is also one of the few cycads to ever be commercially exploited. Its leaves were harvested for use in floral arrangements and were sufficiently popular for plastic imitations to be made once the harvesting stopped after the plants were protected.
