Nepenthes dubia. Single green pitcher.

Nepenthes dubia certainly is one of the least well known species of the genus. It is only recorded from Gunung Talakmau in West Sumatra though there is a lot of confusion with a hybrid between N. inermis and N. talangensis which is found on Gunung Talang. This hybrid resembles it a little. Note the lid of the pitcher which points backwards and the flat peristome. Interestingly N. dubia grows exclusively as an epiphyte.
