Nepenthes khasiana is a Kannenpflanzenart from the family of pitcher plants plants (Nepenthaceae), it is native to India . The first description was in 1873 by Joseph Dalton Hooker .
description
Nepenthes khasiana is characterized by rapid growth. With a height of up to 4 meters (sometimes up to 6 meters), it is a rather smaller type of pitcher plant. The plant forms a climbing, round trunk with a diameter of 8 to 12 centimeters, the leaves are 15 to 46 cm long and 3 to 10 cm wide. The tendril is about 10 to 25 cm long, hairy and relatively slender.
The green pitchers with red-brown stripes are up to 20 cm long and have a diameter of 3 to 4.5 cm. They only have narrow wing strips. The Peristom is 6 to 10 mm relatively narrow. The jug opening and the lid are oval shaped. The jug takes about 64 days to form and then "lives" for an average of 65 days before it disintegrates again. Mosquito larvae of the genus Aedes were found in the jug liquid .
The number of chromosomes is 2n = 80.
distribution
The plant can be found in the Khasi Mountains in the Indian state of Meghalaya (at an altitude of 1000 to 1500 m) and in neighboring Assam . This makes Nepenthes khasiana the only pitcher plant found in India. The area is characterized by very high amounts of precipitation (2400 mm annually). It can get relatively cold at night, and it never gets really hot during the day.
The substrate consists mainly of sand with a proportion of organic matter. The species is acutely threatened with extinction in nature and is therefore also listed in Appendix I of the Washington Convention on Species Protection (CITES).
Interesting
In the homeland the plant is also known as the demon plant ("Tiew-rakot") or the devil's cup ("Memang-koksi").
