Discussion

Of conservation concern.

In Arizona Hexalectris revoluta grows in Cochise and Pima counties; in Texas, in the Guadalupe and Chisos mountains.

Hexalectris revoluta has a less densely flowered raceme than H. nitida, and more revolute sepals and petals, and more deeply lobed labellum than H. spicata, both species with which it is occasionally confused. The plants are occasionally associated with Acacia, Juglans, and Prosopis in Arizona (R. A. Coleman).
