État de la populationExpert
The species has been initially described as a common Cyperaceae in savanna habitat around Neghelli (Chiovenda et al. 1939) and as rare around Mega (Chiovenda 1951). The species hasn't been listed on the Flora of Ethiopia and Eritrea (Edwards et al. 1997).

Description complète des menacesExpert
In the Somali Acacia-Commiphora bushlands and thickets ecoregion, habitats have become degraded in many places through grazing by livestock and fuelwood collection, particularly close to villages and towns. The Ethiopian montane ecoregions have also suffered as a result of conversion of land for agriculture (Magin and Mockrin 2001).
