Drosera zonaria

Drosera zonaria, the painted sundew, is a perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to south-west Western Australia, from near Perth southeast to near Esperance. It grows in a tight rosette about 5 to 7 centimetres across, with 20 to 30 green to red leaves arranged in concentric layers; the leaves are usually described as kidney-shaped with crimson margins. It grows in deep silica sands in open woodland or coastal heathland and flowers only after a bush fire, which is speculated to be caused by the release of ethylene. Its white, sweetly perfumed flowers resemble those of Drosera erythrorhiza. In the dry summer it dies back to a fleshy tuber 10 to 30 centimetres below ground. Planchon described it in 1848 from specimens James Drummond collected near the Swan River Colony, but it flowers so rarely that it was first seen in flower in 1954.
