Drosera orbiculata

A tiny tuberous sundew endemic to a very small area near Gillingarra, north of Perth in Western Australia. It forms a flat rosette about 1.5 cm across with rounded leaves, grows through the cool, wet winter and retreats to an underground tuber in the hot, dry summer. It is related to Drosera rosulata and was described by Lowrie and Marchant in 1992.
