In the UAE, the species occurs in the Hajar Mountains and the Ru'us al-Jibal as well as on some offshore islands (Western 1994, Jongbloed et al. 2003), on Jebel Dhanna (Western 1983), and on Jebel Hafeet (Western 1994). The species is common in the Ru'us al-Jibal up to c. 1,000 m asl (Feulner 2011). It is possible that some occurrences are the result of cultivation. Globally, the species occurs around much of the Mediterranean basin, through the Arabian Peninsula (but excluding the UAE), and parts of Central Asia (Board of Trustees, RBG Kew 2019).

Assessment rationale/justification
This species is widespread in the Hajar Mountains in the eastern UAE, where it generally occurs at higher altitudes. The identity of the species present in the UAE requires confirmation, and the draft Red Data Book for Plants (MEW 2010) notes that the photograph presented for Trichodesma enetotrichum in Jongbloed et al. (2003) actually shows T. africanum. The species is assessed as Data Deficient.

In the UAE, this species is restricted to the Hajar Mountains (Jongbloed et al. 2003), where it is widespread but uncommon (Feulner 2016), the Ru'us al-Jibal (Feulner 2011), and Jebel Hafeet (coll. <a href=""http://purl.oclc.org/net/edu.harvard.huh/guid/uuid/8111c8f6-4643-4c41-9e0e-40a4af264402"">W. Thesiger, 1948</a>; Wadi Tarabat; Fawzi and Ksiksi 2012). In the Ru'us al-Jibal, the species is occasional, from c. 800 to 1,250 m asl (Feulner 2011). The species is absent from Wadi Wurayah National Park (WWNP) according to Feulner (2016; only found in the upper parts of Wadi Siji) but was reported for the protected area by Judas (2016). The species has also been recorded (Sharjah Seedbank & Herbarium) from Fili on the Sharjah-Kalba Road (Sharjah) and from the coast in Ras Al Khaimah, however both these records are excluded as outside the natural range of the species in the UAE. The global range of this species is from north-east Africa, through the Arabian Peninsula to southern Iran and Pakistan (Board of Trustees, RBG Kew 2019).

This is a perennial shrub that grows up to 80 cm (Reza Khan 1992). It flowers throughout the year but peaks between January and May (Jongbloed et al. 2003). It is a poisonous plant that grows in gravel and sand plains as well as wadis (Drew 2000, Jongbloed et al. 2003, Mahmoud et al. 2018). Its presence is known to be a sign of overgrazing as livestock avoid eating it, and so it becomes dominant in grazed areas (Feulner 2011, 2016). However, the flowers of this plant are known to be utilised by adult Plain Tiger butterflies (Gillett 1998).

Taxon distribution as listed in assessment
Within the UAE, it is common and widespread throughout inland sandy regions across the entire country (Jongbloed et al. 2003). Globally, this species is native to countries within the Arabian Peninsula (Board of Trustees, RBG Kew 2019). According to the outcome of the UAE National Red List Workshop (15th-19th September 2019, Dubai), records of Tribulus omanense within the UAE are considered within Tribulus arabicus. This is due to the species material for T. omanense being described a year after T. arabicus by Hadidi, despite the identification appearing to use the same type material. T. omanense was described as occurring throughout the south of the UAE, in sandy areas.

Habitat
Habitat details as listed in assessment
This perennial shrublet species grows within sand plain habitats and has a prostrate growth form (Jongbloed et al. 2003, Mahmoud et al. 2018). The stems can reach up to 70 cm in length, while the leaves are grey-green and oblong, with a pointed tip (Jongbloed et al. 2003). Solitary yellow flowers can be seen between February to September and the fruit is covered in hair, with wings (Jongbloed et al. 2003). This species is known to grazed by camels in Qatar, which may well also be the case in the UAE (Norton et al. 2009).
