Description
A description of Xyris brevifolia is provided in The Flora of North America.
Distribution
Xyris brevifolia occurs in North Carolina, south to Florida, and westward to Mississippi. The distribution from Mississippi to Georgia and Florida, the species conservation status is not ranked/under review. In South Carolina, the species conservation status is critically imperiled. In North Carolina the species conservation status is vulnerable [1].
Ecology
Habitat
In the Coastal Plain in Florida, Xyris brevifolia can occur in cypress depression swamps, coastal mesic flatwoods, wet pine flatwoods, river floodplains, Magnolia virginiana-Persea-Nyssa hammocks, exposed shores of karst ponds, cabbage palm hammock margins, tropical hammocks, coastal swales, and seepage bogs. It has occurred in disturbed areas such as roadside depressions and bulldozed clearing in pine-palmetto flatwoods (FSU Herbarium). Soils include Mandarin (Typic Haplohumods), loamy soil, loamy sand, sandy peat, and Newnan (Ultic Haplohumods) (FSU Herbarium). Associated species include Pinus palustris, Aristida stricta, Serenoa repens, Ilex glabra, Xyris caroliniana, X. ambigua, Rhychospora plumosa, R. fernaldii, Lachnocaulon, Euphorbia telephiodes, and Drosera intermedia (FSU Herbarium). Occurs in pine-palmetto habitat in south Florida, occurrence is infrequent, and have no forage value [2].
