Nepenthes tentaculata is a highland species of pitcher plant native to Borneo and Sulawesi. The species is named for tentacle-like appendages emerging from the upper surface of the lid. In the lower pitchers, a set of narrow wings with long hairs runs down the sides. The pitcher opening is oblique and pinched along the vertical axis, a shape similar to the closely related N. hamata. The size of the pitchers is rather small, around 10 cm in height. I observed the species on the mid slops of Mt Kinabalu, in high canopied rainforest. The species always grows terrestrially, usually in mossy banks.
