There are no significant taxonomic issues associated with this name.

Cyperus cyprius is endemic to Cyprus where it is confined to the wider Troodos mountain range. The species is found at 7-12 locations with approximately 5,000 plants and an unknown population trend. The area of occupancy is suspected to be around 36 km² and is certainly less than 500 km², and the extent of occurrence is c.765 km². The habitat of the subpopulations at the higher altitudes upstream of the water reservoirs is apparently not threatened, but the river parts downstream of the reservoirs and also at the lower altitudes (close to cultivations and villages) the habitat of the species is degraded due to changes in the hydromorphology of the rivers, and a continuing decline in habitat quality is inferred. It is therefore assessed as Vulnerable [B1ab(iii)+2ab(iii)].

Cyperus cyprius is endemic to Cyprus, where it is confined to the wider Troodos mountain range at altitudes from 100-1,550 m. The species is found at seven locations: Spilia, Prodromos, Kryos Potamos, Pera Pedi, Roudias Valley, near Pachyammos and Armou village. Another location near Galata village where the plant was collected in 1880, has been searched repeatedly without results. The area of occupancy is suspected to be more than 36 km² but certainly very much less than 500 km². The extent of occurrence is c.765 km².

The total population is approximately 5,000 plants. There is no information on the population trend of C. cyprius.

Cyperus cyprius is a perennial herb with a creeping rhizome, up to 50 cm high. It has been described as occurring at streams and irrigation channels on igneous mountainside.

The main threats are change in hydrological conditions such as groundwater extraction, dams, or drought as well as management of sites where it occurs. The habitat of the subpopulations at the higher altitudes upstream of the water reservoirs is apparently not threatened. At the river parts downstream of the reservoirs and also at the lower altitudes (close to cultivations and villages) the habitat of the species is degraded due to the threats described above.

There is no evidence that this species is used.

Three subpopulations are located in state forest land (Troodos National Forest Park and Pafos Forest), which are proposed Natura 2000 sites. There is a need to monitor known populations to establish trends and thereby enable a response if there is a decline. It was listed as Vulnerable D2 on the Cyprus Red List (Tstintides et al. 2007).
