Nepenthes graciliflora

Nepenthes graciliflora is a tropical pitcher plant endemic to the Philippines.[4][7] Long considered a synonym of N. alata, it was restored as a separate species in 2013 by Martin Cheek and Matthew Jebb.[4] It has been recorded from the islands of Bohol, Leyte, Luzon, Mindanao, Mindoro, Panay, Samar, and Sibuyan, and following the redelimitation of N. alata is the most widespread Nepenthes species of the Philippines.[4] It is known from mossy, submontane forest, generally at 800–1,280 metres (3,000–4,000 ft) altitude, though the type specimen from Sibuyan was collected at only 300 m (1,000 ft).[4]
