| Distribution | Tidewater region of the Outer Coastal Plain, including the Outer Banks.
Coastal Plain, VA to southern FL, west to eastern TX and central AR; West Indies. | |
| Abundance | Frequent to common. Populations often are dominant or co-dominant in the community and can extend for a several dozen acres in a few locales, such as near Manns Harbor (Dare County). This is clearly an S4 species, not S3 as given by the NCNHP. | |
| Habitat | Brackish and fresh-tidal river marshes, upper edges of salt marshes, interdune swales and marshes. |
| Phenology | Flowering and fruiting July-October. | |
| Identification | This is the famous Sawgrass of the Florida Everglades. Leaves are sharply scabrous along the margins and the midvein, and reach up to 5 feet tall. Flowering stems (culms) project well above the leaves and may reach 8 or 9 feet, with a branching inflorescence 1-2 feet long. You do not want to walk through a stand of Sawgrass, as you can easily cut your skin on the leaves. | |
| Taxonomic Comments | By some taxonomists include it within the near-global C. mariscus as ssp. jamaicense.
