Quillwort Yellow-eyed Grass

Xyris isoetifolia, the quillwort yelloweyed grass, is a plant species native to southern Alabama and to the Florida panhandle, where it is found in coastal plains, Sphagnum bogs, and the edges of sinkholes.

Xyris isoetifolia is a perennial herb up to 40 cm (16 inches) tall. Leaves are rather narrow, and twisted, rarely more than 1 mm in width but up to 15 cm (6 inches) long, thus superficially resembling those of Isoetes.
