Nepenthes may be mentioned as a genus specially developed in the Malayan area, and extending from New Caledonia to Madagascar; it is found as far north as the Khasi hills, and in Ceylon, but does not appear on the Himalaya or in the peninsula of India.
The plant generally understood by this name is Nepenthes, a genus containing nearly sixty species, natives of tropical Asia, north Australia and (one only) of Madagascar.
A structure called the cool orchid house is set apart for the accommodation of the many lovely mountain species from South America and India, such as odontoglossums, masdevallias, &c., and in this the more uniform the temperature can be kept the better, that in summer varying between Cyanophyllum (Miconia) Cycas Dieffenbachia Dipladenia* Dracaena Eranthemum Eucharist Euphorbia Ficus Franciscea Gardenia Gesnera Gloriosa* Gloxinia f Heliconia f Hoffmannia I pomaea * Ixora Jacobinia Jasminum* Luculia Maranta Medinilla Meyenia Musa Nelumbium f Nepenthes Nymphaea f Oxera * Pancratium f Pandanus Passiflora* Pavetta Petraea * Pleroma* Poinsettia Rondeletia Sanchezia Schubertia* Scutellaria Stephanotis Tabernaemontana Terminalia Thunbergia Torenia Thyrsacanthus Tydaea Vinca Abutilon Acacia Agapanthus Agathaea Agave Alonsoa Aloysia Amaryllis Ardisia Asparagus Aspidistra Asystasia (Mackaya) Azalea Bauera Begonia Blandfordia Bomarea * Boronia Bougainvillea * Bouvardia Brugmansia Calceolaria Camellia Campanula Canna Celosia Cestrum * Chorizema* Chrysanthemum Cineraria 60° and 65°, and in winter from 45° to 60°.
Among the orders more strongly represented in Sumatra than in Java are the Dipterocarpaceae, Chrysobalanaceae, sclerocarp 1Vlyrtaceae, Melastomaceae, Begonias, Nepenthes, Oxalidaceae, Myristicaceae, Ternstrbmiaceae, Connaraceae, Amyridaceae, Cyrtandraceae, Epacridaceae and Eriocaulaceae.
- Pitcher of a species of pitcher-plant (Nepenthes distillatoria).
The forty species of Nepenthes are mostly natives of the hotter parts of the Indian Archipelago, but a few range into Ceylon, Bengal, Cochin China, and some even occur in tropical Australia on the one hand, and in the Seychelles and Madagascar on the other.

Thus Nepenthes secures a supply of nitrogenous food from the animal world in a manner somewhat similar to that adopted by the British sundew, butterwort, and other insectivorous plants.
