While orchid hunting recently we found two all-white Fairy Slippers, the albino or alba form of the species and its western variety. They are, therefore, Calypso bulbosa var. occidentalis fma. nivea. It is easy to think that one has found this form since all the Fairy Slippers fade and turn nearly white when they are finished blooming, and there are very pale forms of the species that are nearly white, but the obvious difference is the color on the back of the lip or pouch, brownish purple in all but the pure white form and yellowish-green in that form. We found only two this season in different places after finding four last season, but one was nearly finished when we found it. We made several trips to see and photograph them.
