| Distribution | Verified only from New Hanover County, so far collected from 3 different places, including Carolina Beach State Park and along the road to Eagle Island. First found in 1969 in ballast near the old US 17 bridge over the Northeast Cape Fear River by Steve Leonard and Julie Hackney. A specimen from Brunswick County appears to be misidentified, as it lacks creeping stem/rhizomes, and the leaves are too short.
Pantropical, in N.A. on the Gulf Coastal Plain. Several inland and more northern records are waifs or adventives.

| Abundance | Very rare and local. | |
| Habitat | "Wet brackish soil along road to Eagle Island"; sandy ballast near old US 17 bridge; Carolina Vegetation Survey plot at Carolina Beach SP in red cedar--live oak--palmetto woodland. | |
| Phenology | Flowering and fruiting late August-October. | |
| Identification | This species grows from a creeping stem and rhizomes that root at nodes. The plant is bluish green (glaucescent). It does send up an erect inflorescence, a rather conical/triangular panicle. | |
| Taxonomic Comments | The genus Panicum in the broad sense was once very large, but with the split of Dichanthelium in the 1980s, it has been reduced to manageable size. In more recent decades, other genera have been split off: Coleataenia, Hymenachne, Kellochloa, and Phanopyrum, as examples. All 6 of these genera can be readily told from each other in the field with just a hand lens. For a more detailed discussion, see the introductory paragraphs in Weakley (2018). | |
