About Cladium mariscus subsp. intermedium Kük.
Cladium mariscus, the parent species of Cladium mariscus subsp. intermedium Kük., is a flowering plant in the sedge family. Its common names include swamp sawgrass, great fen-sedge, saw-sedge, and sawtooth sedge; it was previously called elk sedge. This species is native to temperate Europe and Asia, where it grows in base-rich boggy areas and along lakesides. It can reach up to 2.5 metres (8 ft 2 in) in height, and its leaves have hard serrated edges. In the past, Cladium mariscus was an important material used to build thatched roofs. Harvesting the plant was an arduous task, because its sharp edges can cause deep lacerations.
