|Known for:||common name Lady's Slipper or Slipper Orchid; long, twisting petals and large, pouchlike labellum|
|History:||name is derived from the Greek phragma, which means "division", and pedium, which means "slipper" in reference to the divisions of the flower's ovary and the slipper-shaped labellum|
The flower features long, moustache-like petals and a large pouchlike labellum that is curved inwards at the margins. The lower two sepals are fused into a synsepal. A unique shieldlike staminode is visible.
The flower possesses an ovary that is trilocular (having three cavities) as opposed to unilocular (having one cavity), as in Paphiopedilum.
