Species
Taxon distribution as listed in assessment
In the UAE, the species is known from a very small number of records from higher elevations (900-1,800 m elevation; M. Tsaliki pers. comm. 2019) in the Ru'us al-Jibal. Feulner (2011) reported a single locality in the southern Ru'us al-Jibal, but commented that it is probably overlooked elsewhere and later found a second record in the same area (G.R. Feulner, in litt, in MEW 2010). It has also been recorded from Jebel Jais at high elevation (M. Tsaliki pers. comm. 2019). The global range of this species is the eastern Himalaya and western Himalaya regions, according to Plants of the World Online (Board of Trustees, RBG Kew 2019). Ohba and Rajbhandari (2012) give the range as Nepal, western Himalaya (India, Pakistan, Afghanistan) and southwest Asia. Iran and China are cited by Flora Iranica (Rechinger 1963-2010). The species has recently been reported for Oman (Patzelt 2015).

Assessment rationale/justification
In the UAE, the species is known from three records from the Ru'us al-Jibal. There is no information available on population size and trend, but the species is assumed to be impacted by climate change. The area of occupancy (AOO) is inferred to be restricted, certainly very much less than 500 km<sup>2</sup>, but it is not known if the species is severely fragmented. The number of locations is restricted, defined by climate change, based on the currently known localities. The species is assessed as Near Threatened as a precaution, on the basis of the restricted EOO and AOO, and further research is required. Although the species occurs in adjacent parts of these mountains in Oman, there is no rescue effect applied.
