|Native:||the genus comprises some 80 accepted taxa including several natural hybrids; native to Indo-Malesia (South China, India, Southeast Asia and the Pacific Islands) and India|
|Type:||occur among humus layers as terrestrials on the forest floor, while a few are true epiphytes and some are lithophytes|
|Size:||various sizes; some species have twisting petals as long as 12 inches|
|Flowering:||the inflorescence is erect or somewhat pendent with one or several showy flowers; flowers can last for 6 weeks or more|
|Colors:||variety of colors and patterns with spots, stripes, or venation; some petals have warts and hairy edges|
|Flowering stem:||stem is a short and hairy with green or tessellated leaves that are arranged oppositely; when older shoots die, newer ones take over; each new shoot only blooms once when it is fully grown, producing a raceme between the fleshy, succulent leaves|
|Pseudobulb:||lacks pseudobulbs, instead, it grows robust shoots, each with several leaves; some are hemicryptophytes|
|Roots:||roots are thick and fleshy and grow horizontally; potted plants form a tight lump of roots that, when untangled, can be up to 1 m long|
|Known for:||commonly referred to as Lady's Slipper or Slipper Orchid due to the unusual shape of the pouch-like labellum of the flower; highly collectible by orchid fanciers for their extraordinary flowers|
|History:||the genus name was established by Ernst Hugo Heinrich Pfitzer in 1886; name is derived from Paphos, a city on Cyprus sacred to Aphrodite, and Ancient Greek pedilon "slipper"|
The short column has two lateral fertile anthers, a fleshy apical staminode and two pollinia.
The pouch traps insects seeking nectar, and to leave again they have to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower.
