Var. Faxoni, Bailey, Coult. Bot. Gaz. XIII., 87.

Spikes shorter than in the species, usually short-peduncled, erect or nearly so, much more densely flowered, part of them usually contiguous at the top of the culm, rendering the shorter staminate spike inconspicuous; perigynium usually much larger. (Bailey.) Lake Mistassini, N.E.T. (J. M. Macoun.) Common at Belleville, and westward through the northern part of Ontario to Nipigon River, north of Lake Superior and south-west to Kakabeka Falls, west of that lake. This is evidently the northern form, and is quite distinct in appearance from the species. Many of the eastern references very likely belong here. (Macoun.)

C. arctata x flexilis, Bailey.

C. Knieskernii, Dew. Sill. Journ. 2d. Ser. II., 247, (1846.) I agree with Prof. Bailey in believing that this is a hybrid between C. arctata and C. flexilis. Where I gathered the specimens at Kaka-beka Falls, on the Kaministiqua, thirty miles from Fort William, Lake Superior, both of these species were found growing in profusion. Specimens of C. flexilis, sent from Tobique Lake, N.B., by Wetmore, contained a fine clump of C. Knieskernii. It is just possible that after all it is a lax form of 0. flexilis, as it certainly approaches that species very closely.

(2655.) C. flexilis, Rudge, Linn. Trans. VII., 98, (1804.)

C. blepharophora, Gray, Ann. N. Y. Lyc. III., 237, (1836.)

Newfoundland. (Budge.) Near Weldford Station; Red Bank Creek, and Tobique River; common at Petitcodiac, N.B. (Fowler, Cat.) Jupiter River, Anticosti; Falls of Ste. Anne des Monts, Gaspé Co., Q. (Macoun.) Dartmouth River, Gaspé Basin, Gaspé Co., Q. (J. Bell.) Red Bay, Lake Huron; Nipigon House, Lake Nipigon; abundant at Kakabeka Falls, at Current River, and Otter Head, Lake Superior. (Macoun.) Lake Mistassini, N.E.T. (J. M. Macoun.)

(2656.) C. Assiniboinensis, W. Boott, Bot. Gaz. IX., 91, (1884.)

A very beautiful and distinct species well described by Boott. Peri gynium few-ribbed towards the base, hairy, gradually contracted into a very long slender beak, which is white and membranous at the tip; scale white, awl-shaped, the lower ones awned and longer than the perigynium, the others about the same length. In thickets at the Assiniboine Rapids, east of Brandon, and in the Grand Valley, leading to Rapid City, 1879; on a dry limestone point at the "Narrows" of Lake Manitoba, Man., 1881. (Macoun.) Griswold, Man. (Rev. W. A. Burman.)

(2657.) C. longirostris, Torrey, Schweinitz, An. Tab. (1823.)

C. Sprengelii, Dew.; Spreng. Sys. Veg. III., 827, (1826.) C. longirostris, var. minor, Boott, Phila. Acad. Sc. 78, (1863.) C. longirostris, var. microcystis, Boeckeler, Linnaea, XLI, 241, (1877.) Growing in large tufts sparingly on rocky ledges or in thickets. Andover, and Sussex, N.B. (Fowler, Cat.) Ledges, King's Mountain, near Chelsea, Q.; abundant in a coppice at Hemlock Lake, New Edinburgh, Ottawa. (Fletcher, Fl. Ott.) On Gibson's Mountain, Prince Edward Co.; on the "Big Boulder," Trent Talley, above Trenton, and on limestone ridges, Marmora, Hastings Co., Ont. (Macoun.) River bank, London, Ont. (Burgess. Millman.) Souris River, Man. (Burgess.)

Thickets, along the Kaministiqua, twenty miles above Fort William; rather common at Portage la Prairie and westward to Fort Ellice, in the Assiniboine Valley; rather uncommon on grassy slopes near the Bow River, at Morley, Alberta. (Macoun.) Carleton House to Rocky Mountains. (Hooker, Fl.)

(2658.) C. Saskatchewana, Boeckeler, Linnaea, XL!., 159,

(1876.) This species has been described from young specimens collected by Douglas somewhere on the Saskatchewan. We have seen nothing to tally with the description, and can make no suggestion regarding its proper disposition. Boeckeler places it next to 0. vaginata, and Bailey near C. debilis. Better specimens are much needed.

(2659.) C. capillaris, Linn. (1753); Hook., Fl. II., 227.

C. capillaris, var. elongata, Olney, Prel. Cat. Wheeler's PL. 53. Quite common on the rocky borders of northern lakes and streams. Newfoundland. (La Pylaie.) Bass River, Kent Co.; Edmonton, and Kennebeccasis Bay, N. B. (Fowler, Cat.) Boundary Lake, N. B. (Pringle.) Esquimaux Island, Mingan, Q. (St. Cyr.) Salt Lake, South West Point, and Ellis Bay, Anticosti; common on exposed points, Gaspé coast; very common around Lake Superior, and northward to Lake Nipigon. (Macoun.) Lake Mistassini, N.E.T.; The Twins, James Bay. (J. M. Macoun.) Michipicotin River, Ont. (B. Bell.) Assiniboine Rapids, east of Brandon, Man.; rather common on the margins of streams and ravines from Morley westward through the Rocky Mountains to Roger's Pass, summit of the Selkirk Mountains, B.C.; McLeod's Lake, lat. 55°, and Peace River Pass, lat. 56°, B.C. (Macoun.) Lewes River, lat. 62° north of British Columbia (Dawson.) Fort Norman, Bear Lake, and Rocky Mountains. (Hooker, Fl.) Ounalashka. (Bothr. Alask.) Greenland. (Lange.)

Var. Krausei, Krantz. (MSS.)

C. Krausei, Boeckeler, Engler's Bot. Jahrb. VII., 279, (1886.) Dr. August Krantz, who has carefully examined the whole collections of Krause made in Alaska, writes me that Boeckeler's new species is only an androgynous form of 0. capillaris, and suggests the above varietal name. Alaska. (Krause.)

(2660.) C. obesa, Allioni, var. minor, Boott, Ill. 161.

C. supina, Wahl. (1802); Hook., Fl. II., 225. We know nothing of this species. None of our specimens are anything like it. Bear Lake, and Rocky Mountains. (Hooker, Fl.) Greenland. (Lange.)

* * Beak bidentate. + Perigynium smooth.

(2661.) C. fulva, Good., Linn. Trans. II., 177, (1792); Hook., Fill., 225.

C. Greeniana, Dew. Sill. Journ. XXX., 61, (1836.) Newfoundland. (Goodenough.) Specimens gathered at Ellis Bay, Anticosti, are referred here, and if correctly so, are certainly indigenous. The fertile spikes are usually two, the lower is long pedun-culed, and the upper almost sessile; staminate spike also long pedun-cled. Mr. Arthur Bennett, F.L.S., of England, has confirmed this identification.
