| Distribution | Mostly Coastal Plain and lower Piedmont. The gap in the Coastal Plain is an artifact of collecting. The Macon County specimen appears to be misidentified; it needs careful check.
Native of Eurasia and northern Africa; in N.A. MA to IL, MO, and OK, south to GA and TX; also B.C. to CA and AZ. | |
| Abundance | Fairly common to common in the northeastern quarter of the state; infrequent to fairly common in the southeastern Piedmont and the southern Coastal Plain. Rare in the Mountains (Macon Co., woods along creek, Walking Fern Gap Trail) and in the Sandhills proper. | |
| Habitat | Moist soil along creeks and rivers, seepages, roadside ditches, maritime swamp forests, interdune swales; occasionally in drier habitats. | |
| Phenology | Flowering and fruiting April-July. | |
| Identification | Clustered Dock grows to about 3 feet tall. The lower leaves are lance-shaped or broadly lance-shaped, 5-10 inches long; middle and upper leaves are much smaller and narrower. The inflorescences are terminal and axillary, slender, with small leafy bracts. It can be confused with R. obtusifolius, but differs in having narrower leaves and the fruit margins are entire (vs. coarsely toothed in R. obtusifolius). | |
