In the UAE, the species occurs in the southern Hajar Mountains and on Jebel Hafeet (Jongbloed et al. 2003). The species is absent from the Ru'us al-Jibal (Feulner 2011). There is a single historical record of two plants from a tributary of mid-Wadi Zikt in the Wadi Wurayah National Park buffer zone (Feulner 2016). Gillet (2006) recorded the species from Wadi Khutwa near Al Ain, but it is uncertain if this record is from within the UAE. In the Arabian Peninsula, the species is known from Oman, Saudi Arabia and Yemen (Hjertson 1995), and the United Arab Emirates (Jongbloed et al. 2003). The global range of this species is from the eastern Mediterranean to through Egypt to north-east Africa, and through the Arabian Peninsula to Thailand (Board of Trustees, RBG Kew 2019).
