A. Calypso - Cytherea bulbosa
One of the rarest and at the same time most beautiful of our native Orchids, appearing much like a small Cypripedium (Lady's-slipper). In New York it has been found in several localities in southern Herkimer, in Lewis, Oswego and Onondaga counties. The writer found it several years ago in Lodi or Tamarack swamp near Syracuse, but the place has since been obliterated by the growth of the city. For the illustration used here we are indebted to Edward A. Eames of Buffalo.
