1973 Notes 319 that is known from this area was collected at Fort Chipewyan at the west end of Lake Athabaska in latitude 58°42' N, in what is now the province of Alberta (Raup 1936). This specimen was cited by MacFarlane (1908) in his monograph of the Sarraceniaceae and is probably preserved at Kew. Raup substantiated its occurrence in the Lake Athabaska region when he collected Sarracenia purpurea in a muskeg near Ennuyeuse Creek on the south shore of Lake Athabaska in Saskat- chewan. In spite of the fact that it had been searched for diligently for many years by one of the authors (W.J.C.), there were no specimens specifically recorded from the District of Mac- kenzie. Thus S. purpurea was listed by Porsild and Cody (1968) as a species which was unknown but might yet be discovered in the Continental Northwest Territories. It was therefore of considerable interest when two collections were made from widely separated localities in the District of Mackenzie during the summer of 1971. Data are as follows. MAC- KENZIE DISTRICT: seismic line in a Triglochin maritimum marsh, 1.3 miles south of Mile 92 Mac- kenzie Highway, 60°54' N 116° 55' W, S. Talbot s.n., 27 July 1971 (DAO); common on a level burned part of the peat plateau, fairly moist, with Andromeda, Smilacina trifolia, and Menyanthes, Rabbitskin Creek about 14 miles east of the Mac- kenzie River, 61°45' N 120° 15' W, J. S. Rowe 1910, 16 July 1971 (DAO). At the first site, Sarracenia purpurea was abund- ant in Scorpidium-dommaied, eutrophic wet-level fen apparently similar to a 'Rimpibaunmoor" (Ruuhijarvi 1960). This is quite different from the Sphagnum peat situations in which the Pitcher Plant is frequently found. Here the dominant species were Scorpidium scorpioides, Scirpus caespitosus, Menyanthes trifoliata, Car ex limosa, Campylium stellatum, Myrica gale, Drosera angli,- ca, Andromeda polifolia, Triglochin maritimum, and Equisetum fluviatile.
