Species
Taxon distribution as listed in assessment
This species was first described for the UAE (Wadi Bih, Ras Al Khaimah) in 1999 (Böer and Chaudhary 1999) but a specimen was actually collected earlier, in 1980 (<a href=""http://data.rbge.org.uk/herb/E00361435"">RBG Edinburgh Herbarium</a>: ""Jabal Ruwaydah, at head of Wadi Sidakh; north-facing limestone hillside, 500 m""). The native range is Greece, the southern and eastern Mediterranean, through the Arabian Peninsula, to southern central China (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
This species is known in the UAE from one confirmed record in 1980 from Jebel Ruwaydah in the southern Ru'us al-Jibal of the UAE, and from one later record from Wadi Bih (also Ru'us al-Jibal). Nothing is known of the population size and trend, and confirmation of the distribution and population status of this species is needed. Therefore, the species is considered Data Deficient.
