Drosera margaritacea

A recently described (2021) annual sundew of Drosera section Arachnopus, the Drosera indica group, endemic to the Kimberley region of Western Australia. Its name refers to pearly, milky-white stalked glands on the short petiole. Like its relatives it is a hot-climate annual that grows in full sun on wet, seasonally flooded sandy clay, sets seed and dies as the site dries, so in cultivation it is raised from seed each year.

Where it grows wild

Margins of seasonally flooded sand pits and narrow drainage channels on moist reddish-brown sandy clay, in the open monsoon savanna of the West Kimberley around Derby, Roebuck, Mount Hardman and the King Leopold Ranges.

The records are from the lowland West Kimberley and nearby ranges, roughly sea level to a few hundred metres; the records carry no elevations.
