Marshes along the Grand Trunk Railway, three miles east and five miles west of Belleville, Ont., and in low boggy places, Crow River, close to the bridge at Marmora, Hastings Co., Ont. (Macoun.) Wet ground near the Ottawa and Prescott Railway, Prescott, Ont. (Billings.) Lakes Superior and Huron. (Richardson.) Along the Kaministiqua River twenty miles from Lake Superior; very abundant throughout the whole prairie region, and extending north to Peace River and Lake Athabasca, to the base of the Rocky Mountains at Morley, and in the Columbia Valley at Donald. (Macoun.) Nelson River, Keewatin. (B. Bell.) Cumberland House, and Fort Carleton, on the Saskatchewan. (Hooker, Fl.) This Carex produces much of the marsh hay of the prairie region, and in summer is the chief food of Indian ponies. It never grows in brackish marshes, and all ponds where it grows have good water the whole season.
Dr. Gray and Prof. Bailey place C. mirata, Dewey, under this variety, but I think they are in error, as it has not the characters which separate this form from the species, but rather those of variety imberbis. I believe, however, it is a distinct variety. An examination of Prof. Dewey's Herbarium will decide this, as he had many specimens of it, collected by myself at Belleville, Ont., over twenty years ago. Indeed, the probabilities are that both G. Bella-villa and C. mirata equal G. livida, var. divergens, Bailey.
