Glyceria laxa (Lamson-Scribner) Lamson-Scribner. Common name: Lax Mannagrass. Phenology: Jun-Aug. Habitat: Bogs, fens, seeps, wet meadows. Distribution: PE south to NC, mostly Appalachian.
Origin/Endemic status: Native
Taxonomy Comments: Though often described as a hybrid of G. canadensis and either G. striata var. striata and/or G. grandis var. grandis, G. laxa ranges south of the distribution of both G. canadensis and G. grandis var. grandis. It is best considered as a species, perhaps of hybrid origin.
