The largest genus of pitcher plants is Nepenthes, the so-called tropical pitcher plants, which contains approximately 150 species (researchers have yet to agree upon the precise number), plus numerous hybrids and cultivars. As this genus contains all of the species present within the taxonomic family Nepenthaceae, this means that the latter family is the largest family of pitcher plants. There are three separate families in total.

Although widely distributed across the Old World tropics, the greatest concentration of tropical pitcher plant species occurs in southeastern Asia, most notably Borneo, Sumatra and the Philippines, which contain many endemic species, and exhibit the conditions of high humidity and precipitation that these plants prefer. They are also referred to as monkey cups, because when their pitchers are full of rain water, monkeys will often drink out of them.
