Thanks Jackie and BettyDon. I had no idea they were so tricky to i.d.

Xanthorrhoea australis has a definite trunk above ground. It is extraordinarily difficult to ID the species with underground trunks, even in flower and with the bracts around the flowers and between the flowers intact. One of the characters in the Plantnet key is th relative length of flower stalk and flower spike.

The absence of prominent cluster bracts over the flower spike rules out X. australis, the upper aspect of the leaf appears flattened to concave in some, this is also inconsistent with X. australis, therefore this is likely either X. resinosa or the affiliated X. concava.
