| Distribution | The single specimen was collected by G. McCarthy in eastern NC in 1885, most likely at a seaport such as Wilmington. BONAP maps it in New Hanover County.
Native of southern Europe; in N.A. NY and Ont. south to SC, MO, and TX; also Pacific states. | |
| Abundance | Very rare. | |
| Habitat | No NC data. | |
| Phenology | Flowering and fruiting -- no NC data. | |
| Identification | Seaport Goosefoot may recall C. album and both have ovate leaves with a few marginal teeth and 2 basal lobes or processes. Apparently C. opulifolium never has lance-shaped leaves as in some C. album, and the lateral basal lobes are large. | |
| Taxonomic Comments | Members of the genus are often found in saline to brackish sites, but also fallow fields, waste lots, and other highly disturbed places. Each flower produces male and female parts plus a calyx; they are very small and not at all showy. Weakley's (2018) key must be used with care, and a dissecting scope is almost essential for successful identification. | |
