Species
Taxon distribution as listed in assessment
This is an occasional species that is found near groundwater in wadis or springs in the Hajar Mountains in the eastern UAE (Jongbloed et al. 2003). It is more common in the Hajar Mountains than in the Ru'us al-Jibal, where it is known from a single site ('Ayn as-Sih; Feulner 2011) in Oman. This plant species has a cosmopolitan global distribution (Board of Trustees, RBG Kew 2018).

Habitat
Habitat details as listed in assessment
This species is a perennial sedge, rush-like with creeping rhizomes, found in and near freshwater (Jongbloed et al. 2003, Al Meharibi et al. 2019), in gravel wadi beds with shallow groundwater, and other freshwater features such as seepages and springs (Feulner 2011). In Wadi Wurayah, it is found beside small springs and pools, and in low numbers around the waterfall (Feulner 2016).

LC
Assessment rationale/justification
This species is found in the Hajar Mountains in the eastern UAE. It is relatively common in suitable habitat, and whilst its freshwater habitat (groundwater-fed streams and seepages, pools and wet areas) are susceptible to over-abstraction of groundwater and declines in rainfall, the species is considered Least Concern at present.

Conservation
Threats listed in assessment
The species would be susceptible to the over-abstraction of ground and surface water, however, the scope and impact of this within the range of the species in the UAE are not known. Long term declines in rainfall as a result of climate change is likely to impact the species.
