The Egg-in-a-nest Orchid is a terrestrial Venus Slipper orchid of the genus Paphiopedilum, that bears white flowers that are spotted with dark purple dots.

The lip of the flower is modified into a slipper-like, egg-shaped pouch, also covered in purple spots, yet much smaller in size than those on the petals, and resembling a spotted bird's egg.

In Thai, it is known as rong thao narih fah hoi, literally ‘Clam Valve Lady’s Slipper’.
