Stephanachne is a genus of three species, that grow in Western China, Mongolia, and Tajikistan. Its members have deeply bilobed lemmas, the lobes being acuminate or aristiate, a line of hairs that at the top of the lemmas that runs across the base of the lobes, and a rachilla extension.
Its closest relative appears to be Trikeraia, from which it differs in having a rachilla extension. This extension also sets it apart from most other stipoids.
There are three species:
Stephanachne monandra
Stephanachne nigrescens
Stephanachne pappophorea
