''Cladium'' ('''Fen-sedge''', '''Sawgrass''' or '''Twig-sedge''') is a genus of large Sedge s, with a world-wide distribution in tropical and temperate regions. These are plants characterized by long, narrow (grass-like) leaves having sharp, often serrated (sawtooth-like) margins, and Flower ing stems 1-3 m tall bearing a much-branched inflorescence. ;Species The number of species is disputed, with different authors accepting between two and 60 species as distinct. The following is a selection of species.
''C. jamaicense'' is common throughout the tropical Americas, one typical and well-known area of extensive saw-grass growth is the Florida Everglades ; saw-grass is the plant referred to by the descriptor, "River of Grass". Across the Everglades, ''C. jamaicense'' occurs in patches of dense growth surrounded by areas of very sparse growth. Because of the sharp, saw-like serrulations on the blades, dense beds of saw-grass can be dangerous to attempt to navigate through (the blades easily cut flesh). Consequently, the dense saw-grass beds harbor little animal life, but (in the Everglades) are the habitat used by Alligator s to build nests (Lodge, 1994). It is also considered to be Indigenous to the Hawaiian Islands , where it dominates a considerable portion of the largest marsh in Hawai‘i , Kawai Nui Marsh . REFERENCES
