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.
