Abstract
Spiranthes dendroneura, a new species from the pine-oak forests of northwestern Mexico, resemblesS. parasilica andS. valerioi in the slender leafless flowering habit, the solitary, tuberously thickened root, and the calli at the base of the lip, but differs by the distinctive shape of the lip which lacks a red central thickening.
