Taxonomy

It is unclear whether this genus should be classified in the lower or higher epidendroids.

Xerorchis has 8 pollinia, hence similar to the more advanced epidendroid genera of Epidendreae and Arethuseae. Yet its morphology, with unthickened stems and persistent leaves, is that of a bambusoid grass and makes it more similar to Tropidieae or Triphoreae.
