Drosera occidentalis
Drosera occidentalis is one of the smallest pygmy sundews: an open rosette about 1.5 cm across with circular leaf blades only about 1 mm wide. Its marginal tentacles can catapult small prey such as springtails into the centre of the leaf. It grows on the edges of seasonal swamps and in damp peaty-sand depressions in far south-west Western Australia. It is wet in the mild, rainy winter and sets gemmae in late spring, before the summer drought.
Where it grows wild
Swamp margins, damp depressions and seasonally wet sedgeland on grey peaty sand. A recent herbarium label from near Cape Le Grand reads 'seasonal swamp, grey, peaty sand. Sedgeland.' The plants sit among low sedges and get strong but slightly broken light.
A lowland species. The few GBIF records with an elevation are at about 15–90 m, with one at 350 m.
