Nepenthes alata (/nᵻˈpɛnθiːz əˈlɑːtə/; Latin: alatus "winged") is a tropical pitcher plant endemic to the Philippines. Like all pitcher plants, it is carnivorous and uses its nectar to attract insects that drown in the pitcher and are digested by the plant. It is highly polymorphic, and its taxonomy continues to be subject to revisions.
N. alata can vary strongly in colouration and morphology. The floral formula is ✶ K4 A4+4+1* G0 for staminate (the apical stamen /*/ may not be present) and ✶ K4 A0 G(4) for pistillate flowers.
Nepenthes alata has long been treated as a highly polymorphic species spanning all the major islands of the Philippine archipelago (with the possible exception of Palawan). Under this broad circumscription, N. alata was understood to have an altitudinal range of 0–1,900 m (0–6,234 ft) above sea level and was recorded from, among others, the islands of Bohol, Camiguin, Cebu, Culion, Leyte, Luzon, Mindanao, Mindoro, Negros, Panay, Samar, and Sibuyan. Nepenthes alata in this broad sense (sensu lato) is one of the easiest and most popular Nepenthes in cultivation.
