Drosera zonaria, the painted sundew,

bush fire, which is speculated to be caused by the release of ethylene. Its white, sweetly perfumed flowers, which are very similar to those of D. erythrorhiza, emerge on 4 to 5 cm tall scapes.[1][2][3][4][5] As with most other tuberous Drosera species, D. zonaria will die back during the dry summer months and retreat to the fleshy tuber 10 to 30 cm below ground.[6]

D. zonaria tuber, beginning to emerge from dormancy

D. zonaria flowers so rarely that very few botanists have ever witnessed the event.

type specimen was even recorded under the name D. erythrorhiza at Royal Botanic Gardens, Kew. The species was finally rediscovered near Guildford in 1952 by M. C. Russell, who then also saw it in flower for the first time in May 1954.[7] By the time Rica Erickson wrote her 1968 book Plants of Prey in Australia, no other flowering specimen of D. zonaria had been found.[10]
