Taxon distribution as listed in assessment
This species was first recorded for the UAE in 1996 from cliffs on Jebel Qitab at c. 1,000 m asl (Feulner 1997) and this remains the single known site for the species in the UAE. The species is locally common at a small number of localities above c. 800 m elsewhere in Hajar Mountains in Oman (including Jebel Akhdar and Jebel Ghaweel; Feulner 1997). It is absent from the Ru'us al-Jibal in the UAE (Feulner 2011). The species has an EOO and an AOO of less than 20 km<sup>2</sup>. Jongbloed et al. (2003) show the species in the Wadi Khabb Shamsi gorge, in Oman. The native range of this species is from southern Africa, through the Arabian Peninsula, to northwestern India (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
This species was first recorded for the UAE in 1996; this single know location at Jebel Qitab, from c. 650 m to c. 1,000 m asl, still remains. The species has an extent of occurrence (EOO) and an area of occupancy (AOO) of less than 20 km<sup>2</sup> and occurs in one location, based on drought and the potential threats of grazing. G.R. Feulner (in litt, MEW 2010) reported a maximum of 30 plants, perhaps fewer than 20, and there was little or no regeneration seen. The species is assessed as Critically Endangered (CR D) based on the number of mature individuals being less than 50. Whilst the species occurs at other sites within the Hajar Mountains in Oman, it is thought that there is little opportunity for a rescue effect, and the assessment remains CR.
