Ch'ien Lee: Ch'ien C. Lee is a photographer and botanist specialising in the carnivorous plant genus "Nepenthes".  Lee has described several new "Nepenthes" species, including "N. baramensis" (now known as "N. hemsleyana"), "N. chaniana", "N. gantungensis", "N. glandulifera", "N. jamban", "N. lingulata", "N. palawanensis", "N. pitopangii", and "N. platychila".  Lee also described the natural hybrid "N. × bauensis".

Anoda cristata: Anoda cristata is a species of flowering plant in the mallow family known by many common names, including spurred anoda, crested anoda, and violettas.  Its exact native range is unclear but it probably spans Mexico and part or all of Central America.  It is known throughout the rest of the Americas as well as Australia as an introduced species and often a noxious weed.  This is an annual herb reaching a maximum erect height between one half and one meter.  The stem is ridged and branching.  The plant is variable in morphology, especially in leaf shape, but leaves are usually somewhat triangular, and hairy.  Solitary flowers grow in the leaf axils.  The flower is 2 to 3 centimeters wide, with pointed green to reddish sepals and lavender petals.  The fruit is a bristly, disc-shaped capsule with 9 to 20 segments.  Each segment produces a seed.  This is sometimes an agricultural weed, especially of soybeans.  It is tolerated as a weed of crop fields in parts of Mexico, and even fostered, because it is eaten and used as a source of medicinal remedies.

It is based on the 2009 monograph, "Pitcher Plants of the Old World", and, unless otherwise stated, all information is taken from this source.

Anoda: Anoda is a genus of flowering plants in the mallow family.  There are 23 or 24 species of these herbs, most native to Mexico and South America.  They are generally erect plants with a variety of leaf shapes, and many bear colorful flowers.  Most bear distinctive disk-shaped segmented fruits.

Nepenthes boschiana: Nepenthes boschiana ( ; after Johannes van den Bosch), or Bosch's Pitcher-Plant, is a tropical pitcher plant endemic to Borneo.  It is most closely allied to "N. faizaliana".  "Nepenthes borneensis" is considered a synonym of this species.  "Nepenthes boschiana" has no known natural hybrids.  No valid forms or varieties have been described.  "Nepenthes boschiana" belongs to the loosely defined ""N. maxima" complex", which also includes, among other species, "N. chaniana", "N. epiphytica", "N. eymae", "N. faizaliana", "N. fusca", "N. klossii", "N. maxima", "N. platychila", "N. stenophylla", and "N. vogelii".

Nepenthes chaniana: Nepenthes chaniana ( ; after Datuk Chan Chew Lun, Managing Director of Natural History Publications (Borneo)) is a tropical pitcher plant species belonging to the genus "Nepenthes".  It is characterised by a dense indumentum of long, white hairs.  Pitchers are cylindrical and mostly white to yellow in colouration.  "Nepenthes chaniana" belongs to the loosely defined ""N. maxima" complex", which also includes, among other species, "N. boschiana", "N. epiphytica", "N. eymae", "N. faizaliana", "N. fusca", "N. klossii", "N. maxima", "N. platychila", "N. stenophylla", and "N. vogelii".

List of Nepenthes natural hybrids: This list of "Nepenthes" natural hybrids is a comprehensive listing of all recorded natural hybrids involving species of the carnivorous plant genus "Nepenthes".  Hybrids that are not endemic to a given region are marked with an asterisk.

Nepenthes: Nepenthes ( ), also known as tropical pitcher plants, is a genus of carnivorous plants in the monotypic family Nepenthaceae.  The genus comprises roughly 150 species, and numerous natural and many cultivated hybrids.  They are mostly liana-forming plants of the Old World tropics, ranging from South China, Indonesia, Malaysia and the Philippines; westward to Madagascar (two species) and the Seychelles (one); southward to Australia (three) and New Caledonia (one); and northward to India (one) and Sri Lanka (one).  The greatest diversity occurs on Borneo, Sumatra, and the Philippines, with many endemic species.  Many are plants of hot, humid, lowland areas, but the majority are tropical montane plants, receiving warm days but cool to cold, humid nights year round.  A few are considered tropical alpine, with cool days and nights near freezing.  The name "monkey cups" refers to the fact that monkeys have been observed drinking rainwater from these plants.
