Nepenthes thorelii is a tropical pitcher plant endemic to Indochina. Very little is known about N. thorelii and it is unlikely to have entered cultivation, although various other taxa are often mislabelled as this species in the plant trade. Prior to its rediscovery in 2011, N. thorelii was considered possibly extinct, both in the wild and in cultivation.

Nepenthes mirabilis, or the common swamp pitcher-plant and tropical pitcher plant, is a carnivorous plant species. By far the most widespread of all Nepenthes, its range covers continental Southeast Asia and all major islands of the Malay Archipelago, stretching from China in the north to Australia in the south. The species exhibits great variability throughout its range. One of the more notable varieties, N. mirabilis var. echinostoma, is endemic to Brunei and Sarawak and possesses an extremely wide peristome.
