Cypripedium yatabeanum, known as the spotted lady slipper[4] or palomino lady's slipper,[5] is a species of terrestrial orchid in the family Orchidaceae.[6][7] It is native to Alaska (including the Aleutian Islands), to the Russian Far East (Kamchatka and the Kuril Islands), and northern Japan.[3][8] It is distinguished from the closely related Cypripedium guttatum by its yellow-green flowers and narrower, longer lip.[5] It is a perennial herb that grows up to 2 ft (0.61 m) tall.[9] Its habitats include mesic tundra, marsh borders, and beach dune lag.[8]
