- Comments
- Study of the varieties of Panicum virgatum by Bruce Sorrie turned up Virginia specimens of this variety at the University of North Carolina Herbarium (NCU), published in J. Bot. Res. Inst. Texas 12(1):61-62 (2018). Careful study of specimens of P. virgatum in Virginia herbaria may reveal additional records. Field work seems to indicate the species is only of sporadic occurrence but careful study of specimens of P. virgatum in Virginia herbaria is needed to confirm this. Distinguished by broader leaves, denser panicles, longer spikelets, and culms from a knotty crown or short rhizome rather than an elongate rhizome.
- Habitat
- Oligohaline tidal marshes and upper borders of salt marshes. Apparently infrequent along estuarine rivers of the c. and n. Coastal Plain.
- Native Status
- Native
