Grasstrees

Xanthorrhoea () is a genus of about 30 species of succulent flowering plants in the family Asphodelaceae. They are endemic to Australia. Common names for the plants include grasstree, grass gum-tree (for resin-yielding species), kangaroo tail, balga (Western Australia), yakka (South Australia), yamina (Tasmania, from the palawa kani language), and black boy (or "blackboy"). The most common species is Xanthorrhoea australis, and some of these names are applied specifically to this species.
