Sri Lankan pitcher plant

Nepenthes distillatoria is endemic to Sri Lanka and is the only Nepenthes species recorded from the island. It grows in waterlogged open scrub, along road embankments and other cleared areas, and in forest. N. distillatoria occurs from sea level to 700 m altitude. Due to its isolation, N. distillatoria has no known natural hybrids.

Nepenthes distillatoria was the second Nepenthes species to be described in print, after N. madagascariensis. In 1677, Danish physician Thomas Bartholin made brief mention of it under the name Miranda herba, Latin for "marvelous herb". Three years later, Polish–Dutch merchant Jacob Breyne referred to this species as Bandura zingalensium, after a local name for the plant. Bandura subsequently became the most commonly used name for the tropical pitcher plants, until Linnaeus coined Nepenthes in 1737. Nepenthes distillatoria was again described in 1683, this time by Swedish physician and naturalist Herman Niklas Grim. Grim called it Planta mirabilis destillatoria, or the "miraculous distilling plant", and was the first to clearly illustrate a tropical pitcher plant. Three years later, in 1686, English naturalist John Ray quoted Grim as saying:

The root draws up moisture from the earth which with the help of the sun's rays rises up into the plant itself and then flows down through the stems and nerves of the leaves into the natural utensil to be stored there until used for human needs. [translated from Latin in Pitcher-Plants of Borneo] Linnaeus used Grim's original specific epithet when naming N. distillatoria in 1753.

Nepenthes distillatoria was again illustrated in Johannes Burmann's Thesaurus Zeylanicus of 1737. The drawing depicts the end of a flowering stem with pitchers. …
