Nepenthes jamban

Nepenthes jamban is a pitcher plant species endemic to the Barisan Mountains of northern Sumatra, Indonesia. It was found during field trips in 2004-2005, first collected in April 2005 south of Padang Sidempuan in North Sumatra, and described in 2006 in the journal Blumea. The epithet jamban is the Indonesian word for 'toilet' and refers to the shape of the pitchers. It grows at 1,800-2,100 m in summit scrub of upper montane mossy forest and, unlike the related N. jacquelineae, only on the ground. The thin stem grows to about 4 m and is purplish red. Lower pitchers are small, rarely over 5.8 cm tall and 4.4 cm wide, and yellowish orange to bright red. Upper pitchers are much larger, up to 12 cm tall and 5.2 cm wide, widely funnel-shaped in the upper half with an almost horizontal mouth; they are bright yellow with a yellow to orange peristome, and the underside of the lid bears large glands. Like N. inermis it produces thick, sticky pitcher fluid and often catches large prey such as wasps and crickets. In Japan, nursery-raised plants from specialist growers appear at online auctions. It is a high-mountain plant that dislikes heat and needs cool summer nights.
