Cyperus papyrus
Flooded areas are not the only places where it can grow, a study of the phytosociology on the islands of Lake Ziway, an Ethiopian Rift Valley lake, identified a common plant community dominated by "Ae. elaphroxylon" and "Sesbania sesban", with "Euphorbia tirucalli" and "Acacia tortilis" as co-dominant species, and characterised by the presence of "Withania somnifera". This community occurred at an altitude of 1,673m and slope of 5%. The vegetation along the shores of Lake Ziway is composed of bulrush ("Paspalidium geminatum"), papyrus ("Cyperus papyrus"), blue water lily ("Nymphaea nouchali") and "Ae. elaphroxylon". In Arsi Negele (woreda) in Oromia region in southeastern Ethiopia, where it is called "boboffee", it occurs in Kimphe Lafa forest, a remnant of dry afromontane forest. It also occurs in the Gughe-Amaro Mountains in the southwest Ethiopian highlands.
