(2818.) D. Californica, Bolander, Proc. Calif. Acad. II., 182.
Rather common in tufts at Old Wives Lakes, east end of Red Deer Lakes, and west of Calgary, through the foot-hills of the Rocky Mountains to Canmore, within the mountains; rather common on dry soil around Cedar Hill, and throughout the southern part of Vancouver Island, and Nanaimo, Qualicum, and Alberni. (Macoun.) North point of Texada Island, B.C. (Dawson.) Near Victoria, Vancouver Island. (Fletcher.) The Vancouver Island form is between the species and D. unispicata, and seems to unite them.
(2819.) D. intermedia, Vasey.
A most interesting grass in its peculiar range and change of habit. Along Jupiter River, Anticosti; summit of Mount Albert, Gaspé, Q., alt. 4,000 feet; very abundant in the prairie region, from Portage la Prairie westward to the source of the Qu'Appelle; on the Cypress Hills, and from Calgary westward through the Bow River Pass, Rocky Mountains, to the Columbia Valley; at Goldstream, Wellington Mine, Departure Bay, summit of Mount Mark, near Qualicum, and on rocks along Barclay Sound, Vancouver Island. (Macoun.) Prairies at Emerson, Man. (Burgess.) Red River, Man., 1827. (Douglas.)
Dry sandy woods, from the Atlantic to the Pacific; not rare but local. Dry banks, Pictou, N.S. (Macoun & McKay.) Baddeck, Cape Breton. (Burgess.) Dry soil, Glenelg, Guysboro Co., N.S. (Faribault.) Dry barrens; common at Bass River, N.B. (Fowler, Cat.) Tobique River, N.B. (Hay.) Montmorency River, Q. (St. Cyr.) Tadousac. Q. (A. T. Drummond.) Vicinity of Ottawa. (Fletcher, Fl. Ott.) Abundant in sandy meadows and almost everywhere around Prescott, Ont. (Billings.) Very common on all dry and sandy soils at Belleville, and westward to Red Bay, Lake Huron. (Macoun.) Vicinity of Hamilton, Ont. (Logie.) Port Colborne, Lake Erie. (McGill Coll. Herb.) Sandy woodlands, London, Ont. (Burgess. Millman.) Lake of the Woods. (Burgess.) Little Flat Rock Portage, Lake Nipigon; twenty-five miles up the Kaministiqua, and on sandy soil around Lake Superior; Red Deer River, lat. 53°, Man.; rather common in the Rocky Mountains, at Hector, and on dry slopes, Columbia Valley; sandy woods, Nanaimo, and at Sproat Lake, Alberni, Vancouver Island. (Macoun.) Specimens approaching D. sericea were gathered at Saugeen, Ont., by Dr. Burgess, and by myself at Red Bay, Lake Huron, and Red Deer River, Man. The Vancouver Island specimens approach D. intermedia, and it seems to me that further examination will reveal the existence of intermediate forms uniting all three in one multiform species.
(2821.) D. unispicata, Munro. in Herb.
D. Californica, var. unispicata, Thurber, Bot. Calif. II., 294. Not uncommon on the south and south-western slopes of the Cypress Hills, Alberta. (Macoun.) Vancouver Island. (Fletcher.)
