Microthelys is a genus of about 10 species found in the forested mountains of central America with a single species extending northward into New Mexico. Plants in this genus produce a small number of leaves that form a basal rosette which may be present at flowering. The labellum of the tubular flowers usually displays a red-orange area corresponding to slightly raised, fleshy calluses.
