| Distribution | Present over the southern coastal counties, and slightly inland, ranging from Carteret and Sampson counties to the SC border.
This is a Southern Coastal Plain species ranging from southeastern NC to southern FL, and west to eastern LA. | |
| Abundance | Locally uncommon to fairly common in areas with limesink ponds, though generally rare over the range as a whole. The NCNHP tracked the species as Significantly Rare until a few years ago, but has demoted it to Watch List now. | |
| Habitat | In NC, most locations for the species are in limesink ponds, though it does occur in other ephemeral pools, though not in clay-based Carolina bays (as with R. aristosa). Note that R. aristosa does occur in some limesink ponds. |
| Phenology | Blooms from June to September, and fruits shortly after flowering. | |
| Identification | This is a Rhexia with quite narrow opposite leaves, growing along a stem that may have a few branches, and reaching about 1.5-2 feet tall. The leaves are one-nerved (one main vein), linear to narrowly elliptic, about 1.5 inches long and only 1/5-inch wide or less, somewhat hairy as is the stem, and mostly entire. The flowers grow from the branch ends or upper axils and are like others in the genus, being rose to pink, with the 4 rounded petals creating a spread flower about 1.5 inches across. This species has a long capsule, with an elongated neck (longer than the rounded body) and with many glandular hairs over the capsule. Normally, to identify this species, the narrow opposite leaves with just a single obvious vein, and growing in a limesink pond, should be this species. Check the capsule to be sure. | |
