Within the UAE, it occurs throughout the Hajar Mountains and in the Ru'us al-Jibal (Jongbloed et al. 2003, Judas 2016). It is considered to grow at all elevations (Jongbloed et al. 2003). Globally, the native range of this species spans from the Arabian Peninsula to India (Board of Trustees, RBG Kew 2019).

This species has a restricted distribution in the UAE, where it is known from two sites in the Hajar Mountains. Feulner and Karki (2009) undertook fieldwork to search for the species in suitable habitat in northern Oman and in the UAE, finding the species at just two sites in the UAE; Wadi Shawka and Wadi Wurayah National Park (a single location above the Wadi Wurayah waterfall; Feulner 2016). G.R. Feulner (pers. comm. 2019) also found the species at Wadi Hala (Ras al Khaimah). Saccharum kajkaiense has also been recorded from a locality south-east of Shawqa (Dave Aplin pers. comm. 2019). Given the records from adjacent parts of Oman to the west, south, and southeast of Hatta (including at Wadi Qahfi, part of the 'Hatta Pools'), the presence of the species in suitable habitat (permanent water) within the UAE around Hatta might be expected, but it was not found during surveys by Feulner and Karki (2009). The species may occur at other sites with permanent water, as it is difficult to identify S. kajkaiense amongst the large background populations of S. griffithii (G.R. Feulner pers. comm. 2019). Based on the four currently known localities, the AOO is 16 km² using a 2x2 km grid, although the actual area where this species occurs is very much less, just a few square meters. It is considered to occur at four threat-based locations. The altitude range in the UAE is c. 200 - 450 m asl, but it is found to above 1,000 m in neighbouring parts of Oman. R.A. Western (<a href=""http://data.rbge.org.uk/herb/E00240941"">RBG Edinburgh Herbarium specimen</a>) collected the species in 1990 from Wadi Rayy in Oman, just south of Hatta in the UAE and Cock (2009) collected the species from east of Hatta (Wadi Qahfi), also in Oman. Feulner and Karki (2009) summarise the known records for the UAE and northern Oman. The global distribution of this species is from Afghanistan, Pakistan, and Iran, to the Arabian Peninsula (Oman and the United Arab Emirates; Cope 2007, Feulner and Karki 2009).

This species occurs throughout UAE waters. As is currently understood on the global-level, it is widespread in the Indo-West Pacific (Carpenter and Allen 1989). Its depth range is 0 to 90 m (R. Myers pers. comm. 2015).

This species occurs throughout UAE waters. Globally, it is widespread in the Indo-West Pacific (Carpenter and Allen 1989, Randall 1995). Its depth range is 10-80 m (Carpenter and Allen 1989).

This species occurs throughout UAE waters. Globally, it is widespread in the Indo-West Pacific (Sato and Walker 1984, Carpenter and Allen 1989, Carpenter 2001). Its depth range is 0 to 50 m.

This species occurs throughout UAE waters. Globally, it is restricted to the Western Indian Ocean where it occurs from South Africa, Madagascar, the Mascarenes and the Seychelles to the Red Sea, Arabian Gulf and Pakistan (Carpenter 1989, Carpenter and Allen 1989, Gaudian et al. 1995, Gillibrand 2007, K.E. Carpenter pers. comm. 2014). Its depth range is 1 to 40 m (Carpenter 1989).

In UAE waters, this species occurs only in the Sea of Oman. There are no confirmed records from the Arabian Gulf (W. Smith-Vaniz pers. comm. 2013). Elsewhere, it is circumtropically distributed in tropical waters (Smith-Vaniz 2002, Simon et al. 2013, Friedlander et al. 2014, Smith-Vaniz 2016). The depth range is 1-150 m (Lieske and Myers 1994).

This species is widespread in the Hajar Mountains in suitable habitat (near water in wadis; MEW 2010). It has also been recorded from Abu Dhabi and Al Wagan (A.R. Western, U. Deil and F. Karim; Jongbloed et al. 2003). The species is recorded from Wadi Wurayah (Feulner 2016, Judas 2016). The species is absent or rare in the Ru'us al-Jibal (Feulner 2011). RBG Edinburgh holds specimens from; 1. <a href=""http://data.rbge.org.uk/herb/E00358631"">Wadis around Hatta</a>, (300 m asl), 2. <a href=""http://data.rbge.org.uk/herb/E00358628"">fringing the oasis at Qidfa'</a> (Fujairah), 3. Wadi Ham between Masati and Fujairah, and 4. <a href=""http://data.rbge.org.uk/herb/E00358630"">Abu Dhabi to Al Ain roa</a>d at al Khanza south; this latter record is a long way outside the otherwise known distribution of the species in the UAE, and is discounted here. Globally, this species occurs through the Arabian Peninsula to Iran, the western Himalaya and Bangladesh (Board of Trustees, RBG Kew 2019).

This species is widespread in the Hajar Mountains (Jongbloed et al. 2003, Al Meharibi et al. 2019). The global distribution of this species is from Socotra to Iran (Kirschner 2002, Board of Trustees, RBG Kew 2018).

The species is widespread in the Hajar Mountains and the Ru'us al-Jibal, and has also been recorded from Jebel Hafeet (Jongbloed et al. 2003). In the Ru'us al-Jibal, the species occurs at low to moderate elevations (c.150-950 (1,250 m) in the southern and (outside the UAE) eastern Ru'us al-Jibal (Feulner 2011). the species occurs in Wadi Wurayah National Park (WWNP; Feulner 2016). The native range of this species spans across north-east Africa (Somalia) and the Arabian Peninsula (Yemen to the UAE) (Board of Trustees, RBG Kew 2019).
