Nepenthes viridis is a tropical pitcher plant endemic to the Philippines. It is known only from coastal areas at low altitude and has been recorded from Dinagat, Samar, and a number of surrounding islets. It is closely allied to the N. alata group of species.
The specific epithet is Latin for "green" and refers to the plant's typical yellowish-green pitcher colouration, which is maintained irrespective of sun exposure.
Nepenthes viridis was discovered in 2007 by Thomas Gronemeyer and Volker Heinrich. An account of this and other discoveries appeared in a 2008 issue of the German-language periodical, Das Taublatt, where the plant was treated as a green form of N. alata.
The recognition of this taxon as a new species—under the placeholder name "Nepenthes species 2"—was announced online in September 2012, together with that of four other putative new species from Mindanao and surrounding areas. This followed field work by a team comprising Tobias Gieray, Thomas Gronemeyer, Marius Micheler, David Marwinski, and Andreas Wistuba, though only the last three studied N. viridis in situ that year.
Nepenthes viridis was formally described in a 2013 issue of Das Taublatt, the magazine of the German carnivorous plant society, Gesellschaft für fleischfressende Pflanzen im deutschsprachigen Raum. Among the six describing authors were Marius Micheler, Thomas Gronemeyer, Andreas Wistuba, and David Marwinski, from Germany, and Wally Suarez and Victor B. Amoroso from the Philippines. The botanical description and subsequent discussion were in German and the diagnosis in English.
