Drosera hartmeyerorum

A tropical annual sundew from the Kimberley of northern Western Australia and the Top End, a close relative of D. indica in section Arachnopus. Clusters of bright yellow, mulberry-shaped emergences at the base of each leaf distinguish it from every other sundew; their function is unknown. It grows fast in the hot, wet season on wet lateritic sand, so give it heat, strong light and wet, nutrient-poor sand, and resow from seed each year.

Where it grows wild

It grows in wet Pandanus savanna on lateritic sands and on the sandy margins of seasonally flooded soaks, swamps and creeks. Collectors also record it in seepages, drainage depressions, grassy sedgelands and skeletal soils over sandstone. The ground is saturated in the wet season, but the plants are usually not submerged. The ascending stems reach about 30 cm and scramble as they age.

It grows in lowland tropical savanna, with the few recorded elevations between about 150 and 300 m.
