Xyris curtissii Malme
Comments
Sometimes treated as a var. of Xyris difformis, as by Kral and FNA. However, based on field experience, it seems abundantly distinct from X. difformis s.s. and the morphological differences between the two seem more than adequate to justify treating them as separate species. Even FNA admits "Xyris difformis var. curtissii remains distinct even when mixed with the other two varieties, a common event in the southern Atlantic and Gulf coastal plains."
Habitat
Bogs, sphagnous power-line swales, and seepy pond shores. Rare, inner Coastal Plain, north to Caroline County. Suffolk added 3/4/2024, J. Stanley 1589 (WILLI)
