Just returned from walking in the forests NW of Sydney. A startlingly
beautiful flower of Autumn is the Fringed Lily (Thysanotus tuberosus).
The petals are about 13 cm long. The Aborigines used to eat the
starchy, tuberous roots. So I guess this species now has a denser
distribution than at the time of European settlement.
