DistributionCollected in 2018 by Mark Basinger in Rowan County in the Alcoa Game Land. Surprisingly, this is a long-awaited first known NC record, as even during RAB (1968) times, the species had been collected from many southern SC counties, including as far north as Oconee and Lee counties. However, it is a tiny plant that can be easily overlooked.

Ranges from central-southern U.S. states east to VA and FL, and thus NC had been a "hole" in the range map (Weakley 2022a).
AbundanceVery rare, or overlooked. As it is not on the NCNHP list, the website editors suggest a Watch List status (W7) for now, even with just this one known record. It ought to be found elsewhere in the state with further examination of tiny plants in muddy ground.
HabitatDamp to slightly wet, often disturbed ground, in sunny places -- ditches, savannas, pond margins, etc. This is the type of species that perhaps is ephemeral on exposed mud along pond margins and in ditches. For example, the NC specimen was collected from "moist ruts of logging equipment" in a recently clearcut forest!
PhenologyFlowers and fruits from March to June.
IdentificationThis is a small plant that is branched from a decumbent base, with the numerous "branches" reaching only 3-5 inches high. There are numerous, small, alternate leaves, crowded along the stems -- elliptical and entire but only 3-7 mm (around 1/5-inch) long and slightly narrower in width. The tiny flowers are white and campanulate, in leaf axils -- barely visible to the naked eye.
Taxonomic CommentsHas at times been place in Anagallis and Lysimachia.
