Xyris curtissii is a monoecious perennial forb/herb.[2] However there is some suggestions that X. curtissii by be annual in northern portions of its range while individuals in the southern parts are biennial or perennial.[3] It has linear leaves 5-10 cm long and 2-4 mm wide and its sheath occupies 1/3 to 1/2 the length of the straw-colored tawny leaves. Seeds are ellipsoid and around 0.4 mm long.[4]
Distribution
This species occurs from southeastern Virginia, south to northeastern Florida and westward to southern Arkansas and east-central Texas. Disjunct populations are found in southern New Jersey and Central America.[1]
