Taxon distribution as listed in assessment
Within the UAE, Jongbloed et al. (2003) showed this species as present in the sand and high dunes of Dubai and Sharjah emirates. Perry (2008) considered the species to be present in the Rub Al Khali and widespread in the Liwa/Umm az-Zamul area and commented that the species had been overlooked in the UAE and confused with Calligonum comosum. The species is cultivated along roadsides in many areas (Karim and Dakheel 2006). The native range of this species is through the Arabian Peninsula and east to Pakistan and north-west India (Board of Trustees, RBG Kew 2019).
