Xyris curtissii is a monoecious perennial forb/herb. However there are some suggestions that X. curtissii may be annual in northern portions of its range while individuals in the southern parts are biennial or perennial. 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.
This species occurs from southeastern Virginia, south to northeastern Florida, western and southern Arkansas, and east-central Texas. Disjunct populations are found in southern New Jersey and Central America.
X. curtissii occurs on moist savannas, pine woodlands, pine flatwoods, boggy seepage slopes, river banks, and wet depression prairies. It is also found in disturbed areas including wet open ditches, powerline corridors, and dam margins. Associated species: Rhynchospora spp., Juncus spp., Drosera spp., and Hypericum.
In the southeastern and mid-Atlantic United States, flowering occurs from July through August.
Populations of Xyris curtissii have been known to persist through repeated annual burning.
