Brunoniaceae A monotypic family. Brunonia australis (blue pincushion) is related to Goodeniaceae, which is a small herb with a rosette of leaves, endemic (see ENDEMISM) to Australia and Tasmania and present throughout temperate regions of the country in open communities. The regular, pentamerous flowers are borne terminally on long stems in densely clustered, hemispherical, bracteate heads. The 5 sepals are united in a lobed tube, and the 5 petals are narrow and not winged. The ovary is superior and enclosed in the hollow receptacle. The fruit is a small nut.
