My original intent in writing about our native (all terrestrial) orchids was not nearly as scholarly as the title suggests. In February, when the temperature began to inch toward 90 degrees, I figured that at that rate, by summer the desert would be intolerable. The words "high country" flashed through my mind. A visit to the Grand Canyon in July or August would provide relief from the heat, but I'm sure I'm not the only one who has "done the Canyon" to death. There would have to be a purpose for yet another trip. A field trip to hunt our native orchids was the perfect reason. My search for information about the orchids and for an experienced guide was like a treasure hunt. It led me in many directions: to the Arizona Sonoran Desert Museum, the Desert Botanical Garden, the Arizona Native Plant Society, the ASU Herbarium, Arizona Highways Magazine, free-lance writer Catrien Ross Laetz, and finally to Tim Reeves, a teacher at Navajo Community College. Tim and his wife, Linda, have photographed all of the orchid species and will publish a book on them. He reports that some of the species have not been seen or photographed for 50 years! Publication date of the book is not known because at this point, the text has not been written. Tim also reported that he has led field trips in the 1970's with the OSA. And for our veteran members, you may remember that Linda (Mankel) Reeves is a past president of the OSA (1978 and 1979). Tim is amenable to serving in future as a guide for an OSA field trip, but this summer he will be doing graduate work out of state. Meanwhile, for brave souls who wish to wander alone to the high country, the following guide may prove helpful.

The largest and showiest of the genera are the Cypripedium and the Calypso.
