Nepenthes Carolus Linnaeus, 1737 and 1753
Nepenthes are tropical lianas (perennial, vine-like stems) with long leaves which end in pitfall traps designed catch and digest insects and many other copepods, which people refer to as "pitchers" as they can hold water. Most species produce traps which visually imitate flowers to attract prey, hence the pitchers tend to be colorful and very ornate. Even species like N. albomarginata and N. ampullaria that do not appear to imitate flowers produce attractive pitchers.
The pitchers form at the ends of tendrils, one trap per leaf. Sometimes larger prey, like small frogs and mice will also be caught by the largest pitchers, but these traps are not designed to digest such large meals. There are at least 120 species, each with various and often beautiful coloration schemes and some widespread species have dwarf and giant varieties. There are also many natural hybrids, usually where ever species overlap.
