Panicum dichotomiflorum Michaux var. puritanorum Svenson. Section: Dichotomiflora. Puritan Panicgrass. Phen: Jul-Oct. Hab: Wet sands and peats of seasonally exposed pond and lake shores. Dist: NS, NH, and NY south to DE (Sorrie & LeBlond 2008), VA, NC, and e. SC (Bradley et al. [in prep.]); disjunct in IN and IL.

Origin/Endemic status: Native

Taxonomy Comments: Plants from DE northward typically have slender culms 0.3-6 dm long and leaves 1-8 mm wide. Plants with floral characters of var. puritanorum but with nominate-like stout culms 0.8-2 m long and leaves 7-25 mm wide occur in bottomlands in se. VA, and have been recognized as P. dichotomiflorum var. imperiorum Fernald. For the time being they are placed here based on floral characters (they will key here), but need further study.
