| Distribution | The BONAP map shows a record for Pitt County, and Weakley's (2020) map shows it as "rare" in the NC Coastal Plain, perhaps referring to this record/report, but saying "disjunct (perhaps introduced only) in NC and FL." Unfortunately, SERNEC does not show any collections for NC in its database. There is a single record for VA, in the far north -- an historical record for Arlington City.
This is a Northern species, ranging south to NJ, PA, IA, and OR -- and disjunct to NC and FL (where probably not native in either state). | |
| Abundance | Very rare if still present (Pitt County). The NCNHP rank it in 2022 as SU (Undetermined), with a Watch List status of W4 (Perhaps not native). Weakley's (2020) map shows Native but his text is more speculative if native or not. The website editors are a bit more skeptical -- that even if the record is confirmed -- such that it is best to consider the species of uncertain provenance, possibly not native, with a suggested rank of SE?. | |
| Habitat | Strictly in wetlands -- marshes and swamps. | |
| Phenology | Flowers and fruits from July to September. | |
| Identification | This species has slender and mostly leaning stems that can be 2-3 feet long or tall. There are small bulblets in many of the upper leaf axils. It has very slender leaflets that give it a distinctive and "sparsely-leaved" look that is quite different from the much wider leaflets of the common C. maculata. | |
