Taxon distribution as listed in assessment
This species is known from few records in the UAE. Jongbloed et al. (2003) cite two records by R.A. Western from coastal areas of Ajman and Umm al Quwain (<a href=""http://data.rbge.org.uk/herb/E00043043"">RBGE Herbarium</a>; R.A. Western; 1985, ""Umm al Quwain to Moola Road""). <a href=""http://data.rbge.org.uk/herb/E00043042"">RBGE</a> also hold a specimen (K. Müller-Hohenstein 1986) from dunes near Al Awir (Dubai). G. Brown (pers. comm. 2019) has only seen the species once in the UAE, near coastal sandsheets in Umm Al Quwain. R.A Western collected the species from ""Ruus al Jibal summit"" in 1985 (Western 1985), precise locality not known and possibly not within the UAE. The estimated EOO of this species is 2340 km<sup>2 </sup>and it is considered to occur at fewer then 10 threat-based locations. The global range of this species is through the Arabian Peninsula to Egypt and the eastern Mediterranean (Board of Trustees, RBG Kew 2019).

Habitat
Habitat details as listed in assessment
Schimpera arabica appears to grow near to coastal sand sheets. R. Western collected it from a sandy hollow in settled sand (R.A. Western RBGE specimen) and again from the summit of the Ru'us al-Jibal (Western 1985), while K. Müller-Hohenstein collected the species from inland dunes.

Assessment rationale/justification
This species has a relatively restricted range, with an estimated EOO of 2340 km<sup>2</sup>. Due to coastal development and grazing from nearby camel farms, it is inferred to be experiencing an ongoing decline in the extent and quality of its habitat. In addition, it is estimated to occur at fewer than 10 locations. Therefore, it is assessed as Vulnerable.
