C. jamaicense is park throughout a tropical Americas, of these average & easily-known locality of extensive saw-grass incubation is the Florida Everglades; saw-grass is the plant referred to by the descriptor, "River of Grass". Through a Everglades, C. jamaicense occurs inside patches of heavy incubation surrounded by areas of super thin incubation. Because of a sharply, saw-prefer serrulations on the blades, heavy beds of saw-grass may be unsafe to attempt to navigate across (the blades easy cut flesh). Consequently, a heavy saw-grass beds harbor little carnal life, however (in a Everglades) come the home ground utilized by alligators to build nests (Lodge, 1994). These are too considered to become indigenous to the Hawaiian Islands, where it dominates the considerable part of the big marsh around Hawai‘i, Kawai Nui Marsh.
