Baker's cord grass
This cord grass is frequently found growing in brackish to fresh marshes, flatwoods, prairies, and lake margins from the peninsula west to the central panhandle of Florida (Wunderlin, 2003). It blooms from spring to fall and usually occurs in wetlands (estimated probability 67%-99%), but occasionally found in non-wetlands. Its long erect light-green leaves are almost completely rolled and tapered to sharp points making it look somewhat rush-like.
Baker’s cord grass is a large grass. from short rhizomes; stems clump-forming, 3 to 6 ft. tall; leaf blades often rolled and pointed (or somewhat flattened), to 2 1/2 ft. long, to 1/4 in. wide, sandpapery on the upper side; inflorescence 3-7 in. long, comprised of 3-14 branches that ascend near the axis; flowers conspicuous, only on the undersides of the branches; spikelets flattened.
