Abstract
Drosera rotundifolia, a species of the temperate Northern Hemisphere with a disjunct occurrence in high montane West Papua, has been discovered in a highland peat bog on Mt Limbawon, Pantaron Range, Bukidnon on the island of Mindanao, Philippines, which mediates to the only other known tropical, Southern Hemisphere location in New Guinea and the closest known northern populations in southern Japan and south-eastern China. A dichotomous key to the seven Drosera species of the Philippines is given, and distribution maps are provided.

Keywords: Drosera; Droseraceae; Malesia; Mindanao; Northern Hemisphere - Tropics disjunction; Philippines; carnivorous plants
