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.

Geographic Range [top]

Population [top]

Population:Possibly restricted to a single population on the mountain slopes. Has been collected on several occasions at this locality, although not recently.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:A shrub found growing on mountain summits.

Use and Trade [top]

Use and Trade: ntain the alkaloid ephedrine and are valuable in the treatment of asthma and many other complaints of the respiratory system (Plants for a Future 2010).

Threats [top]

Major Threat(s): The plant is grazed by camels and goats, its fruits are eaten by jackals (Maire 1932), but these are not considered to be major threats.

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.
