- Comments
- The native Phragmites genotype; see comments under the map for Phragmites australis. With some difficulty, Phragmites americanus may be distinguished morphologically from P. australis; see Saltonstall, et al., in Sida 21:683-692 (2004). However, Haines (Botanical Notes 13, 2010) makes a reasonable argument for species status. In Virginia it occurs in fresh to oligohaline marshes along tidal rivers and is presently known from only a few stations. Further field and herbarium work will likely add additional records to the map. This species is relatively "well behaved" compared to the massively invasive P. australis; it typically occurs in small, loose colonies intermixed with other native tidal species.
- Habitat
- Freshwater to slightly oligohaline tidal marshes. Apparently uncommon or rare in the upper estuarine zones along rivers of the c. and n. Coastal Plain.
- Native Status
- Native
