Clustered Bur Reed

Sparganium glomeratum (Laest. ex Beurl.) Beurl.

Comments

provided by eFloras
Sparganium glomeratum is apparently rare, or perhaps is only rarely collected, in North America, except it is locally common in sedge-marshes and black-ash swamps near the western end of Lake Superior. The species is rather invariable throughout its circumboreal range (C. D. K. Cook and M. S. Nicholls 1986).

Sparganium glomeratum

provided by wikipedia EN

Sparganium glomeratum, the clustered bur-reed,[1] is a species of bur-reed. It is a water plant native to high elevation lakes and marshes of Europe, Asia, and North America. North American populations were doubted as introduced due to its scarce and scattered populations, but a recent herbarium survey found more localities of the species in the central of Canada, concluding the species as circumpolar species.[2]
