Justification: With so few known collections it is uncertain whether E. tilhoana represents a good species or is an outlying population of E. distachya. Further surveys are needed in the type locality to confirm the status of E. tilhoana, which, if recognized as a distinct species is likely to be highly restricted and possibly threatened.

Conservation Actions [top]

Conservation Actions:	The Tibetsi mountains are under no formal protection. No seed has been collected for this species and no collections are known from botanic gardens. Surveys in the area are needed to see if the plant is still extant and to gather collections so that identification can be determined as it may be an outlying population of E. distachya.
