South of W.Va. and Va., this northeastern species is known only from a few cooler Appalachian localities. It was discovered below sandstone cliffs at two close localities in WOLF by D. Dourson (Campbell et al. 1989), mostly growing on slightly drier ground above large patches of Oxalis montana on lower slopes. Without flowers, it can be mistaken for a stunted Lysimachia quadrifolia. It is much shorter (ca. 1-2 dm versus 3-9 dm), with only one whorl of leaves, but it has one of the highest chromosome numbers of North American Primulaceae; 2n = 96.
