Description
A description of Xyris caroliniana is provided in The Flora of North America.
Distribution
Xyris caroliniana is common in the moist sands of pine flatwoods or savannas, well-drained sands or moist depressions of mesic to scrubby flatwoods, sandhills, and scrub throughout Florida and the Coastal Plain regions of the eastern United States[2] with disjunct populations in western Cuba.[3]
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, X. caroliniana has been found in mesic sandy meadows; seepage slopes with Rhynchospora; sandy loam of burned wiregrass-longleaf pinewoods; sandy peat of pine-palmetto flatwoods; sand of open slash pine woodland bordering Hypericum marshes; oak scrub at margin of pine flatwoods; wiregrass-palmetto-slash pine plantation; sandy peat of flatwoods bog; upper edge of grass-sedge bog; wet pine flatwoods; mixed hardwood/cabbage palm hammocks; sandy peat of hillside bogs; mixed pine-oak woodlands; dry boggy areas near small stands of cypress; sandy dune hallows; sandy loam at edge of Ilex myrtifolia depression swamp; turkey oak/longleaf pine barrens; and in sand around ephemeral ponds.[4][5] In disturbed habitats this species has been found in roadside ditches; semi-disturbed remnant of longleaf pine-saw palmetto flatwoods; borrow pit bog; and in sandy peat of drained and bulldozed flatwoods bog.[2]
Xyris caroliniana is frequent and abundant in the North Florida Mesic Flatwoods, Central Florida Flatwoods/Prairies, and Upper Panhandle Savannas community types as described in Carr et al. (2010).[6]
Substrate types include sandy loam, sand, sandy peat, and fine sand.[4]
Associated species include Rhynchospora, Hypericum, Fuirena scirpoidea, Fimbristylis caroliniana, Juncus scirpoides, Rhexia cubensis, Seymeria, Aristida stricta, Conradina, Ilex, Lyonia, Xyris elliottii, Ilex myrtifolia, Serenoa repens, Mitreola petiolata, Xyris flexuosa, Sabatia brevifolia, Kalmia hirsuta, Balduina uniflora, Polygala lutea, Sorghastrum secundum, Quercus pumila, Liatris graminifolia, and Helianthus heterophyllus.[4]
Phenology
X. caroliniana has been observed flowering in February, May through October and fruiting June through October.[4][7]
Fire ecology
Populations of Xyris caroliniana have been known to persist through repeated annual burning.[8]
