Taxon distribution as listed in assessment
The distribution of this species in the UAE has previously been debated due to misidentification for other members of the genus, including Cyperus conglomeratus. The only determinations found are those by L. MacKinnon at RBG Edinburgh Herbarium, representing five specimens from three localities; - <a href=""https://data.rbge.org.uk/search/herbarium/?specimen_num=679006&cfg=zoom.cfg&filename=E00647618.zip"">Sharjah</a>, Dubai road (two specimens; E102; at side of road), 139 m on inland red sand dunes beside the road.- <a href=""https://data.rbge.org.uk/search/herbarium/?specimen_num=678987&cfg=zoom.cfg&filename=E00647633.zip"">Abu Dhabi Emirate</a>; Tarif (two specimens; by side of road, E45), 33 m, inland area of coastal white sand dunes close to edge of sabkha area.- <a href=""https://data.rbge.org.uk/search/herbarium/?specimen_num=678892&cfg=zoom.cfg&filename=E00647666.zip"">Abu Dhabi Emirate</a>, south of Madinat Zayed (one specimen, by side of road, E45), disturbed roadside verge, inland red sand dunes. However, it appears that this species is relatively widespread, occurring across the majority of inland UAE. This species has a wide global distribution from the Sahara, through the Arabian Peninsula, to Pakistan (Board of Trustees, RBG Kew 2019).
