Assessment rationale/justification
This species appears to be known from three areas in the UAE. There are two records from mountains around Hatta (precise localities not known), and the species also occurs on Jebel Hafeet, with an additional record from Ra's Al Khaimah. No recent records from either Jebel Hafeet or from the Hatta area have been found, and nothing is known of the current population size or trend of the species. It has been considered to be 'rare' although 'locally common' in Wadi Tarabat on Jebel Hafeet. It is considered that there is insufficient information to assess the species and it it is placed as Data Deficient.

Taxon distribution as listed in assessment
There are few records of this species from the UAE. Jongbloed et al. (2003) mention two records from mountains around Hatta. <a href=""http://data.rbge.org.uk/herb/E00115616"">RBGE Herbarium hold a specimen from Jebel Hafeet</a> (rocky slopes on hard limestone, 700-1,000 m asl; coll. J.R. Edmondson, 1980), and the species was recorded again from the mountain in 2005 (especially from Wadi Tarabat; Brown 2005). No recent records from either Jebel Hafeet nor from the Hatta area have been found. The native range of this species is from Macaronesia (Canary Islands) across North Africa, to southern Iran (Board of Trustees, RBG Kew 2019).
