Little is known of the distribution, status and systematics of Nepenthes in the Austro-Papuan region and there is some confusion about the number of species present (Clarke & Kruger 2006). A project currently being conducted by staff and students of the Australian Tropical Herbarium and James Cook University in Cairns, Queensland and Monash University, Sunway Campus, Kuala Lumpur, Malaysia, is seeking to redress the situation. The study area extends from northern Queensland across the lowlands of the Trans-Fly Ecoregion in Papua New Guinea and West Papua, Indonesia, in the area south of Young's Line. This line delineates the northern margin of the Australia plate and the area is often contiguous when sea levels are lower, most recently c. 8000 years BP (see Figure 1).
