Fl. South. U.S.500. 1860
Phenology: Flowering late spring–summer (all year south).
Habitat: Acid sandy flatwoods, sandy shores, swales in pinelands, bog edges, coastal plain
Xyris elliottii with its densely cespitose habit, its glossy brown or red-brown, chaffy leaf sheath bases, and narrow leaves is a part of a complex including Xyris baldwiniana and X. isoetifolia. Usually it is readily distinguished by its taller habit, thicker scapes, and larger spikes, but particularly by its strongly contrasting pale, incrassate leaf blade borders. In peninsular Florida, however, this leaf border is not consistently present, particularly in the narrower-bladed populations (in these, leaf blades may be less than 1 mm wide). Such plants can be distinguished from X. baldwiniana by the staminodial brush, absent in X. baldwiniana, and from X. isoetifolia by the different spike shape, the ragged (rather than entire) bracts, and by a different seed sculpture. Hybrids between X. elliottii and X. brevifolia occur in southern Florida.
