Cypripedium yatabeanum, known as the spotted lady slipper[3] or palomino lady's slipper,[4] is a species of terrestrial orchid. It is native to Alaska (including the Aleutian Islands), to the Russian Far East (Kamchatka and the Kuril Islands), and northern Japan.[2][5]

It is distinguished from the closely related Cypripedium guttatum by its yellow-green flowers and narrower, longer lip.[4] It is a perennial herb that grows up to 2 ft (0.61 m) tall.[6] Its habitats include mesic tundra, marsh borders, and beach dune lag.[5]
