Angophora hispida...Dwarf Apple

Angophoras were called Apples since colonial time, because of their supposed resemblance to apple trees. I'm not so sure.

Xanthorrhoea...Grass Tree, Blackboy

Xanthorrhoeaceae is almost entirely an Australian species (1 or 2 species of Lomandra in New Guinea and New Caledonia). These very slow growing Grass Trees produce long spikes at the end of a scape (not pictured). They are often one of the first group of plants to flower after wildfire. Xanthorrhoea provided food, drink, fibre as well as materials for making implements and weapons for the aborigines.

Centaurium erythraea...Centuary

This common weed (at least in my garden) is a digestive stimulant. In herbal medicine it is indicated in apetite loss (when associated with liver weakness). It is also a useful herb in conditions involving a slugggish digestion and in dyspepsia.

Dianella caerulea var. producta...Paroo Lily

I seem to remember someone once telling me that the berries were used as a plant dye.
