Nepenthes inermis
		N. inermis is arguably one of the most visually appealing species, its small but elegant vase-shaped pitchers have no peristome and a very narrow lid. They inhabit the forest canopy between 2300m and 2600m on the mountains of Central Sumatra. The pitcher liquid is particularly viscous compared to other species which may be to prevent pitcher contents from being washed away in heavy rains. Lower pitchers of this species have not been recorded to date. Cultivation is reported to be very difficult.
