Drosera aquatica

An annual sundew of the Drosera indica group (section Arachnopus) from the monsoon tropics of northern Australia, described by Allen Lowrie in 2014. It grows in seasonal swamps, floodplains and flooded herbfields and can live fully aquatic, floating on monsoon floodwater. Like its relatives it lives for one wet season and survives the long dry season only as seed, so growers treat it as a hot-weather annual raised from seed each year.

Where it grows wild

Seasonally flooded ground in the Top End and Kimberley: margins of seasonal swamps, floodplains, wet herbfields beside streams and floodways, and shallow standing water on plateaus. Herbarium labels repeatedly describe it as growing in seasonal fresh water. The sites are open, sunny wetlands that dry out completely in the dry season.

Lowland: almost all records come from the coastal plains and low plateaus of the Top End, and the one recorded elevation is 390 m.
