Phytolacca rigida Small. Common name: Maritime Pokeweed. Phenology: May-Dec. Habitat: Dune slacks, dune slopes, edges of tidal marshes, disturbed areas on barrier islands, xeric sandhills near the coast. Distribution: DE (reportedly), se. VA south to FL and west to TX in the Southeastern Coastal Plain.
ID notes: In addition to the characters in the key, Phytolacca rigida is usually smaller, with smaller leaves and a "tidier" habit, than Phytolacca americana.
Origin/Endemic status: Endemic
Taxonomy Comments: Caulkins & Wyatt (1990) reduced P. rigida to varietal rank, but it seems distinct at species rank.
Other Comments: In the northern parts of our area, in NC and VA, P. rigida is rather rare, limited to the vicinity of the coast, and less weedy than P. americana.
