| Distribution | This undescribed taxon is endemic to NC. Weakley (2018) states: "So far as is known, restricted to the type site in Onslow County, NC". It is found only in "Calcareous wet savannas" (Weakley 2018). Weakley's data is based on a LeBlond specimen from Sandy Run Savannas, 6 June 2013, LeBlond 6960 (pers. herb.). | |
| Abundance | Presumed very rare, both in the state and globally (endemic to NC). The editors do not have specimen information but will assume the species is extant and not historical; we rank it as S1 for now. | |
| Habitat | "Calcareous wet savannas" (above reference). | |
| Phenology | No data. | |
| Identification | See the key in Weakley (2018). | |
| Taxonomic Comments | An undescribed taxon/species.
A note about Dichanthelium: This genus is not impossible to identify to species! But it takes applied effort over a period of time in order to learn the various species and what their morphological limits are. We strongly recommend that you read the introduction to the treatment in Weakley et al. (2023), written by Richard LeBlond. LeBlond has made order out of near chaos, and his keys work very well for our plants. Most Dichanthelium taxa ("Dichs") do not grow everywhere indiscrimminately, but prefer certain well-defined habitats. Note that most species produce flowers/fruits twice a year -- a vernal period and an autumnal period -- and that measurements of spikelets and achenes are taken from vernal plants. Some species also have a third, or summer, period. In the vernal period there is a single inflorescence at the tip of the stem. In the autumnal period, plants produce elongate branches with bunched (congested) leaves and so look quite different from vernal plants. Inflorescences are produced in leaf axils as well as at the tips of branches. NOTE: Older texts had these species essentially all within the very large genus Panicum. "Dich" species are typically named as "Witchgrass" and Panicum species named as "Panicgrass". | |
| Other Common Name(s) | None. Obviously, Sandy Run is a creek that flows through or near the savanna site, in western Onslow County. | |
