Assessment rationale/justification
This species has a restricted extent of occurrence (EOO) within the UAE and is not considered to be common within this area. The estimated EOO for this plant is around 1,430 km<sup>2</sup>, which falls within the threshold for threatened categories. The species probably occurs in more than ten threat-based locations, but the number of locations is likely to be restricted. Water abstraction and declining rainfall as a result of climate are resulting in population declines. As a result, it is cautiously assessed as Near Threatened due to the restricted distribution within the UAE and declining populations. No regional adjustment is made as the extent of any rescue effect is not known.
