Discussion
Malaxis corymbosa grows in the Santa Rita, Huachuca, and Chiricahua mountains in Arizona. It differs from some of its close relatives in Mexico by having a more flattened and less fleshy lip that is less deeply concave proximal to anthers. Plants have 10–33 flowers open at one time and may produce a much larger number.
The hemipollinaria are apically widely divergent.
