Natural range of Xyris curtissii from USDA NRCS Plants Database.

Common Name: Curtiss's yellow-eyed grass[1][2]

Taxonomic Notes

Synonyms: X. difformis Chapman var. curtissii; X. bayardii Fernald; X. neglecta.[3]

Description

Xyris curtissii is a monoecious perennial forb/herb.[2] 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.[4] 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.[5]

Distribution

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.[1]

Ecology

Habitat

X. curtissii occurs on moist savannas, pine woodlands, pine flatwoods, boggy seepage slopes, river banks, and wet depression prairies.[1][4][6][7] It is also found in disturbed areas including wet open ditches, powerline corridors, and dam margins.[7] Associated species: Rhynchospora spp., Juncus spp., Drosera spp., and Hypericum.[7]

Phenology

In the southeastern and mid-Atlantic United States, flowering occurs from July through August.[1]

Fire ecology

Populations of Xyris curtissii have been known to persist through repeated annual burning.
