Drosera amazonica

Drosera amazonica is a small rosette sundew from the Rio Negro region of the Brazilian Amazon, described by Rivadavia, Fleischmann and Vicentini in 2009. It has spoon-shaped leaves on distinct petioles, held on a short stem that elongates to 10–14 cm. It grows on sandy, waterlogged riverbanks and in shallow puddles near sea level, so it needs hot, bright, very wet conditions all year.

Where it grows wild

Herbarium and observation notes put it on riverbanks by waterfalls on blackwater tributaries of the Rio Negro (the Rio Cuieiras), in igapó (seasonally flooded forest edge), and in clumps in shallow puddles of warm water and mud. These are open, sandy, nutrient-poor, seasonally flooded sites.

Lowland: specimens with an elevation are recorded at 10–20 m, and the whole Rio Negro basin here lies below about 100 m.
