Canada V8W 3S2 ----------------------------------------------------------- LESLIE ABRAM VIERECK (1930-2008) From: _Fairbanks remembers Les Viereck_ by Chris Freiberg, published in News-Miner Sunday, September 7, 2008 and other sources To most Alaskans, Les Viereck is known for being one of the first = climbers of Mt. McKinley and a vocal critic of a =9260s plan to use nuclear = warheads to excavate a harbour on the North Slope. But to the hundreds of people who gathered on September 6, 2008 = afternoon at Georgeson Botanical Garden to remember him, Viereck was known simply as = a good friend and a loving husband and father. =93He was kind of like the Ent from =91Lord of The Rings,=92=94 said = Viereck=92s daughter, Sharon, referring to the humanoid trees from the famous novels = and films. =93He was never hasty, very cautious. That=92s sort of how my = father went through life.=94 Leslie Abram Viereck passed away at his home in Fairbanks on August 31, 2008, after struggling with numerous health issues for the last months. Les was born Feb. 20, 1930, in South Dartmouth, Mass. He grew up in a = small Atlantic fishing town but was drawn to Alaska during his Dartmouth = College years when he and two friends drove a Model A Ford up the Alaska = Highway.=20 Though Viereck loved living in Alaska, it was far from his birthplace of Massachusetts. He was drawn to the then-territory while attending = Dartmouth College, eventually driving a Model A Ford up the Alaska Highway to = settle here. He served in the Army at Fort Richardson in the =9250s, but longtime = friend Dave Klein said Viereck wasn=92t always crazy about being in the = military. =93I remember discussing it with Les, and we both considered going to = Canada, which was not as popular back then,=94 Klein said. =93But he concluded = that he had a lot to stay in Alaska for and we=92d tough it out.=94 It was while in the Army that Viereck and three other men climbed Mount McKinley. At the time, fewer than 10 parties had climbed North = America=92s tallest peak. Viereck had asked for only a month of leave from the Army before making = the ascent, but it took the group just that long to make it to the summit. =93The sergeant was really angry and wanted to place us on AWOL = (=3DAbsent Without Official Leave),=94 said George Argus, who accompanied Viereck = on the climb. =93But the base commander realized that if someone=92s feats are = written up in Life magazine, you probably don=92t want to put them on AWOL.=94 In 1959, after his Army service, Viereck took a research and teaching = job at the University of Alaska Fairbanks. One of his first projects was to = study the environmental impact of Project Chariot, a U.S. Atomic Energy = Commission proposal to detonate a series of nuclear bombs on the shore of Cape = Thompson on the North Slope, blasting a harbor from the tundra to promote the peaceful uses of nuclear power. Edward Teller, the physicist who was the inspiration for Dr. = Strangelove, traveled Alaska to promote the positive economic impact the harbor could have on the state, but Viereck and two other scientists publicized the likely disastrous environmental effects of the plan. The project did not go forward, but Viereck and two other scientists at = the university lost their jobs as a result of their criticism. n 1963, Les took a job with the U.S. Forest Service at the Institute of Northern Forestry. During his tenure with the Forest Service, he wrote a definitive book on trees and shrubs of Alaska. This book was recently republished by the University of Alaska Press.=20 A COMPILATION OF ADDITIONS TO THE FLORA OF THE CONTINENTAL PORTIONS OF NORTHWEST TERRITORIES AND NUNAVUT - NO. 2=20 From: P.M. Catling(1), G. Mitrow(1) and B.A. Bennett(2),=20 (1)Biodiversity, National Program on Environmental Health, Agriculture = and Agri-Food Canada, Wm. Saunders Bldg., Central Experimental Farm, Ottawa, Ontario, Canada K1A 0C6 Email: [catlingp@agr.gc.ca] & (2)Yukon = Department of Environment, Wildlife Viewing Program V5A, Box 2703, Whitehorse, = Yukon, Canada Y1A 2C6 Email: [Bruce.Bennett@gov.yk.ca] =20 Introduction Continuing work on the flora of continental Northwest Territories and Nunavut requires another update to the classic regional Flora produced = by Porsild and Cody (1980) to supplement the first compilation of additions (Catling et al. 2005). Since that compilation several additions have = been published and volumes 5, 19, 21 and 24 of the Flora of North America = have appeared. The maps and in these volumes have been checked for additions = to Porsild and Cody's (1980) text.=20 Although not included in this compilation, botanical research in = continental NT continued in 2006 with a botanical survey of roadsides (Oldham 2007.) = and in 2007 with collections in the region of Norman Wells (Mackenzie and Richardson Mountains) and Enterprise (Catling in prep.) and in 2008 with collections from the north shore of Great Slave Lake (Catling in prep.). The sequence of the additions is alphabetical under the sequence of = families in Porsild & Cody (1980). A list of recent reports requiring = confirmation is included. In the notes section, the species are in alphabetical order. = The common names for additions in the list are taken primarily from Kartesz = and Meacham (1999). In some cases a widely used common name is not = available. Including the 57 additions compiled here and the 94 from the previous compilation (Catling et al. 2005), the flora of Northwest Territories includes approximately 1254 species. Additions to Northwest Territories (NT) and Nunavut (NU) SPARGANIACEAE o _Sparganium fluctuans_ (Morong) B.L. Robins., FLOATING BURR-REED. This species was reported for NT by Kartesz and Meacham (1999) on the = basis of a personal communication from W.J. Cody indicating a voucher specimen = at DAO. The voucher specimen (Baker Creek at Giant Mine, Yellowknife, 62=B0 = 27' N, -114=B0 22' W, 15 Aug. 1949, W.J. Cody 3490 and J.B. McCanse, DAO = 171531) was revised to S. fluctuans by V. Harms in 1996 and has the = distinctively branched inflorescence but is immature. Since the identification appears = to be correct it is accepted in the flora.=20 POTAMOGETONACEAE o _Potamogeton robbinsii_ Oakes, FERN PONDWEED. This species was reported for NT by Porsild and Cody (1980) from a collection made on the Thelon River, now the boundary of NT and NU. The following specimen is = the first confirmed from west of the new boundary of the NT: Parson Lake district, N of Inuvik, two stems collected floating along lake shore, 68.99733, 133.57169, G.C.D. Griffiths & L. Hamilton, GR14, 30 July, 2006 (B.A. Bennett Herbarium) POACEAE o _Deschampsia sukatschewii_ (Popl.) Roschev. Previously included in _D. cespitosa_. It is widespread in NT (Barkworth 2007c).=20 o _Elymus glaucus_ Buckley, COMMON WESTERN WILD RYE. Shown at the approximate location of Fort Good Hope by Barkworth et al. (2007a,b). o _Elymus lanceolatus_ (Scrib. and G.J. Sm.) Gould (including _E. calderi_), STREAMSIDE WILD RYE. Shown at the approximate location of Tuktoyaktuk by Barkworth et al. (2007a,b).=20 o _Festuca auriculata_ Drobow, LOBE FESCUE. Shown from the approximate location of Aklavik by Darbyshire and Pavlick (2007) and also in = Barkworth et al. (2007b). The specimen used for the illustration in the Flora of = North America series was collected by W.J. Cody 12888 and S. Johansson, 17 = July 1963, at Canoe Lake on the east slope of the Richardson Mountains 25 = miles west of Aklavik (DAO). =20 o _Festuca lenensis_ Drowbow, TUNDRA FESCUE. Should be added, see under _F. ovina_ in "Notes" below. In the DAO collection there are = numerous specimens from the region of Aklavik.=20 o _Festuca viviparoidea_ Krajina ex Pavlick subsp. _viviparoidea_, VIVIPAROUS FESCUE. Shown by Darbyshire and Pavlick (2007) from the approximate location Fort Good Hope and listed for NT by Aiken et al. (1996).=20 o _Hesperostipa comata_ (Trin. & Rupr.) Barkworth, NEEDLE-AND-THREAD. Shown at the approximate location of Fort Smith by Barkworth (2007b).=20 o _Panicum capillare_ L. var. _occidentale_ Rydberg, COMMON PANIC GRASS. See Catling (2005a).=20 o _Piptatherum canadense_ (Poir.) Dorn, CANADIAN MOUNTAIN RICE GRASS. Shown for the approximate location of Fort Smith by Barkworth (2007b). o _Poa interior_ Rydberg, INTERIOR BLUE GRASS. Shown for the Mackenzie Mountains by Soreng 2006. Porsild and Cody (1980) treated this taxon as = a synonym of the widespread P. glauca M. Vahl. It was reported for NT by Scoggan (1978) as _P. nemoralis_ L. var. _interior_ (Rydb.) Butters & = Abbe.=20 o _Puccinellia nutkaensis_ (J. Presl) Fernald and Weath., ALASKA ALKALI GRASS. Mapped in the Mackenzie Delta region by Davis and Consaul (2006) and shown for this region in Barkworth et al. (2007b).=20 CYPERACEAE o _Carex stylosa_ C.A. Mey., LONG-STYLE SEDGE. This species was mapped by Hult=E9n (1968, p. 258) for the Mackenzie Mountains in NT south of = Norman Wells. Although not included in Porsild and Cody (1980), there seems to = be no particular reason to reject the report.=20 o _Eleocharis erythropoda_ Steudel, BALD SPIKE-RUSH. See Catling (2005a). o _Schoenoplectus pungens_ (Vahl) Palla (_Scirpus americanus_ auct. non Persoon), COMMON THREE-SQUARE BULRUSH. See Catling (2005a). The specimens collected would be referable to var. _longispicatus_ on the = basis of reddish-brown spikelets and some trigonous achenes but we follow the = most recent treatment in not recognizing varieties.=20 POLYGONACEAE o _Polygonum fowleri_ B.B. Robertson subsp. _fowleri_, FOWLER'S KNOTWEED. Shown for NT and NU by Costea et al. 2005. This taxon was originally reported by Cody et al. (2003) although they did not report = the subspecies. o _Polygonum fowleri_ B.B. Robertson subsp. hudsonianum (S.J. Wolf and McNeill) Costea and Tardif, FOWLER'S KNOTWEED. Shown for NT and NU by = Costea et al. (2005). This taxon was originally reported by Cody et al. (2003) = as P. hudsonianum (Wolf & McNeill) Hinds. o _Polygonum ramosissimum_ Michx. subsp. _ramosissimum_, YELLOW-FLOWER KNOTWEED. Shown for NT by Costea et al. 2005. This was originally = reported by Cody et al. (2003), but without indicating a variety.=20 CHENOPODIACEAE o _Chenopodium leptophyllum_ (Moquin-Tandon) Nutt. ex S. Wats., NARROW-LEAF GOOSEFOOT. See Catling (2005). =09 CARYOPHYLLACEAE o _Arenaria longipedunculata_ Hult., LONGSTEM SANDWORT. Shown for NT by Hartman et al. (2005). Included by Porsild and Cody (1980) in _A. humifusa_ but now recognized as a distinct species. More study of this = group is required. _Arenaria humifusa_ appears to occur primarily east of the Mackenzie River and _A. longipedunculata_ to the west.=20 o _Cerastium alpinum_ L. subsp. _lanatum_ (Lamark) Cesati, ALPINE MOUSE-EAR CHICKWEED. Shown for NT by Morton (2005b). It was previously mapped for NU by Hult=E9n (1956, p. 429). o _Minuartia elegans_ (Cham. and Schlect.) Schischkin in V.L. Komarov et al., ELEGANT STITCHWORT. Shown for NT Rabeler et al. (2005). Included = by Porsild and Cody (1980) in _Minuartia rossii_ (R. Br.) House. o _Sagina procumbens_ L., MATTED PEARLWORT. Shown for NT by Crow (2005). There are two specimens at DAO: weed in front of tourist = information centre in Yellowknife, 19 July 1994, M. Hils, J.W. Thieret. Garden in = front of Northern Frontier Visitor Centre, Yellowknife, 62.45 N, 114.35 W, 1 = Aug. 1997, V. Johnston 218, o _Silene cserei_ Baumg., BALKAN CATCHFLY. See Catling (2005a). o _Stellaria borealis_ Bigelow subsp. _borealis_, BOREAL STARWORT. Shown for NT and NU by Morton (2005c). Included by Porsild and Cody = (1980) in _S. calycantha_ (Ledeb.) Bongard. NYMPHAEACEAE=09 o _Nymphaea tetragonal_ Georgi, PYGMY WATER-LILY. Recently separated from _N. leibergii_ (N. tetragona ssp. leibergii) which also occurs in = NT. _Nymphaea tetragonal_ is currently known from several collections in NT (Catling 2005b).=20 RANUNCULACEAE o _Actaea rubra_ (Ait.) Willd. f. _neglecta_ (Gillman) Robins., RED BANEBERRY (WHITE-FRUITED FORM). See Catling (2005a) but it was actually first reported by Cody (1961) although not mentioned in Porsild & Cody (1980). MALVACEAE o _Malva neglecta_ Wallr., DWARF MALLOW. See Catling (2005a). BRASSICACEAE o _Arabis glabra_ (L.) Bernh., TOWER-MUSTARD. This species is mapped on the southern border of NT by Hult=E9n and Fries (1986), and is also reported from NT by Scoggan (1978). Although Kartesz and Meacham (1999) refer to a voucher at DAO, the folder is empty. Assuming that the = specimen is misplaced, it is accepted. =20 SAXIFRAGACEAE o _Boykinia richardsonii_ (Hook.) Rothrock, RICHARDSON'S BROOKFOAM. This species was included by Porsild and Cody (1980) because they = thought that it would likely occur in the mountains west of the Mackenzie Delta. = The type from which the species was described by Hooker (1833-1840) included = two collections; one apparently from Dr. John Richardson in 1826 (Franklin = 1828) collected during his voyage between the Mackenzie and Coppermine Rivers. Since Richardson's voyage was entirely within the present day NT it is suspected that _Boykinia_ occurred there though it is presently outside = of its known range in northern Yukon and Alaska. o _Chrysosplenium iowense_ Rydb., IOWA GOLDEN-SAXIFRAGE. This species was reported for NT by Kartesz and Meacham (1999) on the basis of the = report in Packer (1983). Although we have not seen a specimen it occurs near to = the boundary of NT in northern Alberta and seems likely so the report is accepted.=20 o _Mitella pentandra_ Hook., FIVE-STAMEN BISHOP'S-CAP. This species was reported for NT by Kartesz and Meacham (1999) on the basis of the = report by Cronquist et al. (1997). We were unaware of a specimen but it was recently collected near the Yukon border (lush, moist alpine meadow at = base of slope, facing SE, Howard's Pass, 62.44786 =B0N, -129.20757 =B0W, 11 = July 2007, R. Rosie 07-HP-015 (DAO 831959).=20 o _Saxifraga hyperborea_ R. Br., PYGMY SAXIFRAGE. This species is mapped for NU from south of Kugluktuk (previously Coppermine) by = Hult=E9n and Fries (1986). Although we have not seen a specimen, there seems no = reason to doubt the record based on its overall distribution and it is apparently = the only member of the _Saxifraga rivularis_ complex found in continental Northwest Territories (J=F8rgensen et al. 2006). Collections treated as = _S. rivularis_ from western NT are now treated as _S. hyperborea_.=20 ROSACEAE o _Potentilla villosula_ Jurtz, There are 3 specimens at DAO so identified by J. Soj=E1k in 1987 (Yohin Ridge, 61=B0 12' N, -123=B0 = 51', Nahanni National Park, 14 July 1975, S.S. Talbot T50=3D23-13, DAO 160925; Keele = River, Mother-in-law Lake, 64 =B0 13' N, -127. =B0 32' W, 27 June 1971, W.J. = Cody 19222 and G.W. Scotter, DAO 610894; Mackenzie Mountains, O'Grady Lake, = 63=B0 00' N, -129=B0 02' W, 23 July 1967, W.J. Cody 16413, DAO 182769). These specimens key to _P. villosula_ using Elven & Murray (2008). BALSAMINACEAE o _Impatiens noli-tangere_ L., WESTERN TOUCH-ME-NOT. This species was not included in Porsild and Cody (1980) although it was mapped for Fort Smith and Great Bear Lake by Hult=E9n and Fries (1986).=20 SCROPHULARIACEAE o _Chaenorhinum minus_ (L.) Lange, DWARF SNAP-DRAGON. See Catling (2005a). RUBIACEAE o _Galium aparine_ L., CLEAVERS. See Catling (2005a). ASTERACEAE o _Achillea millefolium_ L. f. _rosea_ Rand. & Redf., YARROW (ROSE FORM). See Catling (2005a). o _Achillea ptarmica_ L., PEARL YARROW. See Catling (2005a) o _Ambrosia artemisiifolia_ L., ANNUAL RAGWEED. Reported by Strother (2006) but originally reported by Scoggan (1979) from Fort Smith. o _Artemisia dracunculus_ L., DRAGON WORMWOOD. See Catling (2005a). This species was listed as "to be expected" in Porsild & Cody (1980). o _Helianthus annuus_ L., COMMON SUNFLOWER. Mapped for NT by Schilling (2006) but originally reported from NT by Scoggan (1979) from near Fort Simpson. o _Sonchus oleraceus_ L., COMMON SOW-THISTLE. Shown for NT by Hyatt (2006) and there is a specimen in DAO: Fort Simpson, 11 Aug. 1955, W.J. = Cody 9336 and J. M. Matte. =20 o _Symphyotrichum lanceolatum_ (Willd.) G.L. Nesom subsp. _hesperium_ (Gray) Nesom var. _hesperium_ (A. Gray) Semple & Chmielewski, WESTERN = WILLOW ASTER. See Catling (2005a) but first reported by Thieret (1963) from Alexandra Falls.=20 =09 REPORTS REQUIRING CONFIRMATION =09 There are no justifying specimens of the following in the DAO = collection, and we regard them as requiring confirmation.=20 POACEAE o _Agrostis clavata_ Trin., CLAVATE BENT. Mapped for the region of Fort Simpson by Harvey (2007), but not by Harvey in Barkworth et al. (2007b).=20 POLYGONACEAE o _Polygonum aviculare_ L. subsp. _buxiforme_ (Small) Costea and Tardif, AMERICAN KNOTWEED. Shown for NT by Costea et al. (2005). o _Polygonum aviculare_ L. subsp. _depressum_ (Meisner) Arcangeli, OVAL-LEAF KNOTWEED. Shown for NT by Costea et al. _2005). o _Rumex crispus_ Linnaeus, CURLY DOCK. Shown for NT by Mosyakin (2005).=20 o _Rumex sibiricus_ Hult=E9n, SIBERIAN WILLOW DOCK. Shown in NT by Mosyakin (2005). Included by Porsild and Cody (1980) in _Rumex triangulivalvis_ (Danser) Rech. f.=20 CARYOPHYLLACEAE o _Cerastium arcticum_ Lange in G.C. Oeder et al., ARCTIC MOUSE-EAR CHICKWEED. Shown for NT by Morton (2005b), but this is apparently based = on a specimen from Southampton Island (Cody 1071, DAO), and thus not to be = listed for the continental flora.=20 o _Cerastium bialynickii_ Tolmatchew. BIALYNICK'S MOUSE-EAR CHICKWEED. Shown for NT by Morton (2005b). o _Gypsophila elegans_ M. Bieberstein, SHOWY BABY-BREATH. Shown for NT by Pringle (2005). o _Minuartia groenlandica_ (Retzius) Ostenfeld, GREENLAND STICHWORT. Shown for NU by Rabeler et al. (2005). There is a specimen at MTMG = (photo DAO) collected by Anderson in 1885 on the MacKenzie River, but the = locality may be in error.=20 o _Silene sorensenis_ (B. Boivin) Bocquet, THREE-FLOWER CAMPION. Reported for NT and NU by Morton (2005a).=20 o _Spergularia canadensis_ (Persoon) G. Don var. _canadensis_, CANADIAN SANDSPURRY. Shown for NU by Hartman and Rabeler (2005), = possibly on the basis of specimens (photo DAO) once in Lepage's personal herbarium = (and likely duplicated elsewhere) from James Bay, and consequently not to be listed for the continental flora. =20 LAMIACEAE o _Galeopsis tetrahit_ L. var. _tetrahit_, BRITTLE-STEM HEMP-NETTLE. This variety is reported by Kartesz and Meacham (1999) on the basis of a personal communication.=20 NOTES Unless otherwise indicated, these changes are a result of revisions in = the Flora of North America series. More detailed explanations and common = names are provided for the species which are deleted.=20 With regard to the name changes, the old familiar names are provided = first to enable someone using the Porsild and Cody (1980) flora for = identification to conveniently check to see if a more current name is available. o _Alopecurus alpinus_ S.M. in Porsild and Cody (1980) is now correctly called _A. magellanicus_ Lam. o _Arenaria capillaris_ Poir. var. _nardifolia_ (Ledeb.) Regel in Porsild and Cody (1980) is now _Eremogone capillaris_ (Poir.) Fenzl var. _capillaris_.=20 o _Armeria maritima_ (Miller) Willdenow - only one subspecies is currently recognized in NT that being subspecies _sibirica_ = (Truczaninow) Nyman.=20 o _Aster brachyactis_ S.F. Blake in Porsild and Cody (1980) is now _Symphyotrichum ciliatum_ (Ledebour) G.L. Nesom. o _Aster ciliolatus_ Lindley in W.J. Hooker in Porsild and Cody (1980) is now _Symphyotrichum ciliolatum_ (Lindley) =C1 L=F6ve. o _Aster falcatus_ Lindley in W.J. Hooker in Porsild and Cody (1980) is now _Symphyotrichum falcatum_ (Lindley) G.L. Nesom var. _falcatum_. o _Aster junciformis_ Rydberg in Porsild and Cody (1980) is now _Symphyotrichum boreale_ (Torrey & A. Gray) =C1 L=F6ve and D. L=F6ve. o _Aster nahanniensis_ Cody in Porsild and Cody (1980) is now _Symphyotrichum nahanniense_ Semple in J.C. Semple et al. o _Aster pansus_ (S.F. Blake) Cronquist in Porsild and Cody (1980) is now _Symphyotrichum ericoides_ (L.) G.L. Nesom var. _pansum_ (S.F. = Blake) G.L. Nesom. o _Aster pauciflorus_ Nuttall in Porsild and Cody (1980) is now _Almutaster pauciflorus_ (Nuttall) =C1 L=F6ve and D. L=F6ve.=20 o _Aster pygmaeus_ Lindley in W.J. Hooker in Porsild and Cody (1980) is now _Symphyotrichum pygmeum_ (Lindley) Brouillet & S. Selliah. o _Aster spathulatus_ Lindley in W.J. Hooker in Porsild and Cody (1980) is now _Symphyotrichum spathulatum_ (Lindley) G.L. Nesom. o _Aster yukonensis_ Cronquist in Porsild and Cody (1980) is now _Symphyotrichum yukonense_ (Cronquist) G.L. Nesom. o _Astragalus robbinsii_ (Oakes) Gray var. _minor_ (Hook.) Barneby. Robins' Milk-Vetch was not reported by Porsild and Cody (1980) but was reported by Scoggan (1978, p.989) from Great Bear Lake. The record was assumed to be based on Burnaby's atlas (1964), but was not mapped by = Burnaby nor mentioned in his text for NT. There is no specimen at CAN or DAO = from the latter location but there is a specimen at CAN labelled as _A. robbinsii_ from further south in the Mackenzie Valley (63.4333 N., = -123.6333 W., D.E. Reid 700). This specimen has some flowers mostly bluish, a = short raceme and single curved branch 18 cm long that may well have been = prostrate making it a match for the widespread and common _A. alpinus_ L. subsp. _alpinus_. Consequently _A. robbinsii_ is excluded from the flora. o _Carex anguillata_ Drej. was reported by Kartesz and Meacham (1999) on the basis of three specimens at DAO, but is now treated as a synonym = of _Carex bigelowii_ Torr. ex Schwein. in _Flora of North America_.=20 o _Carex anthoxanthea_ J. Presl & C. Presl in C.B. Presl. Grassy-Slope Arctic Sedge, a species chiefly of the Pacific Coast, was reported by Scoggan (1978 p.380) on the basis of a specimen at CAN from the Taltson River. It was not reported from NT by Porsild and Cody (1980), and not recently by Murray (2002). There are no specimens from NT labelled as _Carex anthoxanthea_ at CAN or DAO. Consequently it is excluded. o _Carex exsiccate_ Bailey. Western Inflated Sedge, although shown for NT by Kartesz and Meacham (1999) based on Scoggan (1979 p. 391), was in = fact indicated by Scoggan to occur in Mackenzie District only with a question mark based on Boivin's (1967, p. 484) report which was also accompanied = by a question mark. There are no specimens of _Carex exsiccate_ from NT at = CAN or DAO, and NT was not included in the range indicated by Reznicek and Ford (2002). Thus it is excluded from the flora. o _Cirsium vulgare_ (Savi) Ten. Bull Thistle is indicated for NT by Kartesz and Meacham (1999), on the basis of Hult=E9n and Fries (1986), = but in fact there is no reference to it in the latter publication so it is to = be excluded from the flora. =20 o _Colpodium vahlianum_ (Liebm.) Nevski is now _Puccinellia vahliana_ (Liebm.) Scribn. & Merr. (Davis and Consaul 2006).=20 o _Crepis tectorum_ L. Narrow Leaved Hawk's-Beard was reported as new for NT (Catling 2005) but was previously included by Porsild and Cody (1980). =20 o _Eleocharis macrostachya_ Britton in J.K. Small. Pale Spike-Rush, although included for NT by Porsild & Cody (1980) as a synonym of _E. uniglumis_ (Link) Schultes, is now recognized as a species. It was first reported by Cody (1960), the specimens at DAO having been subsequently revised to _E. palustris_ (L.) Roemer & Schultes in J.J. Roemer et al. =20 o _Erigeron grandiflorus_ Hooker subsp. _arcticus_ Porsild in Porsild and Cody (1980) is now _Erigeron porsildii_ G.L. Nesom & D.F. Murray o _Erigeron purpuratus_ Greene. Some of the material treated as this species by Porsild and Cody (1980) has been revised to _E. denalii_ A. Nelson (Nesom 2006). See also Nesom & Murray (2004) for more information = on this group. o _Erigeron nivalis_ Nuttall, . Reported in NT by Nesom (2006) and listed by Porsild & Cody (1980) as _E. acris_ L. var. _debilis_ Gray. o _Festuca ovina_ L. subsp. _alaskana_ Holmen in Porsild and Cody (1980) is now _Festuca brevissima_ Jurtzev. A number of collections initially identified as the former (at DAO) have been revised to _F. lenensis_.=20 o _Grindelia squarrosa_ (Pursh) Dunal in Porsild and Cody (1980) is now treated as a different species, _Grindelia hirsutula_ Hooker & = Arnott. =20 o _Helictotrichon hookeri_ (Scribn.) Henry in Porsild and Cody (1980) is now treated as _Avenula hookeri_ (Scribn.) Holub.=09 o _Hesperis matronalis_ L. Mother-of-the-Evening was reported by Kartesz and Meacham (1999) on the basis of a communication from W.J. = Cody. The specimen at DAO (W.J. Cody 8567 and J.M. Matte, 4 July 1955) was collected along a _Caragana_ hedge in front of a school at Fort = Providence and is indicated on the label to have been possibly planted; = consequently it is excluded from the flora. o _Hierochloe alpine_ (Sw.) R.S. in Porsild and Cody (1980) is now treated as _Anthoxanthum monticola_ (Bigelow) Veldkamp. o _Hierochloe odorata_ (L.) Beauv. in Porsild and Cody (1980) is now _Anthoxanthum hirtum_ (Schrank) Y. Schouten & Veldkamp. o _Hierochloe pauciflora_ R.Br. in Porsild and Cody (1980) is now treated as _Anthoxanthum arcticum_ Veldkamp. o _Hippuris montana_ Ledeb. Mountain Mare's-Tail was reported from the District of Mackenzie by Scoggan (1979, p.148) and Porsild and Cody = (1980). The justifying specimen for these reports from Brintnell Lake (62.0833 N-127.5833 W, M. Raup and J.H. Soper 9720, CAN) is without flowers or = fruits so differences in these characters (see Hitchcock and Cronquist 1973) = cannot be used to identify it. Although Porsild and Cody (1980) and Cody = (1996) used only the height of the stems to distinguish this species, we = consider this character of little value since small, depauperate plants of _H. vulgaris_ cannot be separated. One of the stems is 16 cm tall, more = then 1.5 times the limit given by Cody (1996) and Porsild and Cody (1980). = This species is excluded from the flora pending collection of specimens more clearly referable to it.=20 o _Leontodon autumnalis_ L. subsp. _autumnalis_, Hawkbit was reported from NT by Kartesz and Meacham (1999), believed to be based a personal communication from W.J. Cody. The only specimen in DAO is a rosette = lacking flowers and fruit and dubiously referable to this species (collected at Inuvik). It is therefore excluded from the flora.=20 o _Melandrium affine_ J. Vahl is now _Silene involucrate_ (Cham. and Schlecht.) Bocquet. o _Melandrium apetalum_ (L.) Fenzl in Porsild and Cody is now _Silene uralensis_ (Ruprecht) Bocquet (as follows) but the synonymy of the group requires further clarification. o _Melandrium apetalum_ (L.) Fenzl subsp. _arcticum_ (Fr.) Hult=E9n is now _Silene uralensis_ (Ruprecht) Bocquet subsp. _uralensis_. o _Melandrium apetalum_ (L.) Fenzl subsp. _attenuatum_ (Farr) in Porsild and Cody (1980) is now _Silene uralensis_ (Ruprecht) Bocquet = subsp. _uralensis_. o _Melandrium drummondii_ (Wats.) Porsild in Porsild and Cody (1980) is now _Silene drummondii_ Hook. o _Melandrium ostenfeldii_ Porsild in Porsild and Cody (1980) is now _Silene taimyrensis_ (Tolm.) Bocquet. o _Melandrium taimyrense_ Tolm., in Porsild and Cody (1980) is now _Silene taimyrensis_ (Tolm.) Bocquet. o _Melandrium taylorae_ (Robins.) Tolm., in Porsild and Cody (1980) is now _Silene involucrata_ (Cham. & Schlecht.) Bocquet subsp. _tenella_ (Tolm.) Bocquet. o _Petasites arcticus_ A.E. Porsild in Porsild and Cody (1980) is now _Petasites frigidus_ (L.) Fries var. _palmatus_ (Aiton) Cronquist. o _Petasites frigidus_ (L.) Fries in Porsild and Cody (1980) is now _Petasites frigidus_ (L.) Fries var. _frigidus_. o _Petasites hyperboreus_ Rydberg in Porsild and Cody (1980) is now _Petasites frigidus_ (L.) Fries var. _frigidus_. o _Petasites palmatus_ (Aiton) A. Gray in Porsild and Cody (1980) is now _Petasites frigidus_ (L.) Fries var. _palmatus_ (Aiton) Cronquist.=20 o _Petasites sagittatus_ (Banks ex Pursh) A. Gray in Porsild and Cody (1980) is now _Petasites frigidus_ (L.) Fries var. _sagittatus_ (Banks = ex Pursh) Cherniawsky.=20 o _Petasites vitifolius_ Greene in Porsild and Cody (1980) is now _Petasites frigidus_ (L.) Fries var. X _vitifolius_ (Greene) = Cherniawsky. o _Phacelia campanularia_ A. Gray. This annual is cultivated as the "California Bluebell," a plant native to the deserts of California. It = was introduced to Fort Saskatchewan, Alberta and a population remained there = for at least 12 years as a garden weed. It was collected once at Norman = Wells (rare in grass near buildings, W.J. Cody 7412 and R.L. Gutteridge, 20 = July 1953, DAO 178352). It may have been planted and without evidence of a self-perpetuating population at Norman Wells is excluded from the flora. = =20 o _Phleum commutatum_ Gaudin in Porsild and Cody (1980) is correctly called _Phleum alpinum_ L. o _Phragmites australis_ (Cav.) Tried. ex Steud. has recently been divided into a North American and Eurasian subspecies within North = America. The North American subspecies and the one occurring in NT is _P. = australis_ subsp. _americanus_ Saltonstall, P.M. Peterson and Soreng.=20 o _Poa laxa_ Haenke. This species was reported by Kartesz and Meacham (1999) on the basis of a personal communication from W.J. Cody with a specimen at DAO. The specimen cannot be located and may have been = revised to another species and so P. laxa is excluded. o _Polygonum alaskanum_ (Small) Wight is now _Aconogonom alaskanum_ (Small) Soj=E1k. o _Polygonum amphibium_ L. in Porsild and Cody (1980) is now _Persicaria amphibian_ (L.) Gray. o _Polygonum lapathifolium_ L. is now _Persicaria lapathifolia_ (L.) Gray. o _Polygonum viviparum_ L. in Porsild and Cody (1980) is now _Bistorta vivipara_ (L.) Delarbre.=20 o _Potamogeton amplifolius_ Tuckerman. Large-Leaf Pondweed was reported for NT by Kartesz and Meacham (1999) on the basis of a personal communication from W.J. Cody indicating a voucher specimen at DAO. The specimen was revised to _P. illinoensis_ T. Morong by E. Ogden in 1966 = and confirmed as that by B. Boivin in 1967 and by R. Haynes in 1995. We = agree with this identification so that _P. amplifolius_ is to be excluded from = the flora of the NT.=20 o _Potentilla villosa_ Pallas ex Pursh, This species was reported for NT by Kartesz and Meacham (1999) on the basis of a personal = communication from W.J. Cody indicating a voucher specimen at DAO. However, we have = not been able to locate a voucher at DAO and _P. villosa_ apparently does = not occur in continental Northwest Territories (Elven & Murray 2008).=20 o _Saxifraga aizoon_ Jacq. var. _neogaea_ Butters, now called _Sedum aizoon_ L. (Aizoon Stonecrop) was known previously in NT only from the extreme E end of Great Slave Lake was reported from another location in Great Slave Lake (62.73325, -110.73238) but the specimen has not been = seen (D. Downing, pers. comm.)=20 o _Sedum lanceolatum_ Torr. Although Lance-Leaf Stonecrop was shown for NT by Kartesz and Meacham (1999) based on Porsild and Cody (1980), = it was in fact only included by Porsild and Cody on the basis of = expectation and since no recent record or justifying specimens have come to our attention, we recommend that it be excluded from the flora.=20 o _Senecio streptanthifolius_ Greene in Porsild and Cody (1980) is now _Packera streptanthifolia_ (Greene) W.A. Weber and =C1 L=F6ve. o _Senecio atropurpureus_ (Ledebour) B. Fedtschenko in Porsild and Cody (1980) is now _Tephroseris frigida_ (Richardson) Holub. o _Senecio congestus_ (R. Brown) de Candolle in Porsild and Cody (1980) is now _Tephroseris palustris_ (L.) Reichenbach. o _Senecio cymbalaria_ Pursh in Porsild and Cody (1980) is now _Packera cymbalaria_ (Pursh) =C1 L=F6ve and D. L=F6ve. o _Senecio hyperborealis_ Greenman in Porsild and Cody (1980) is now _Packera hyperborealis_ (Greenman) =C1 L=F6ve and D. L=F6ve. o _Senecio indecorus_ Greene in Porsild and Cody (1980) is now _Packera indecora_ (Greene) =C1 L=F6ve and D. L=F6ve. o _Senecio kjellmanii_ A.E. Porsild in Porsild and Cody (1980) is now _Tephroseris kjellmanii_ (Porsild) Holub. o _Senecio lindstroemii_ (Ostenfeld) A.E. Porsild in Porsild and Cody (1980) is now _Tephroseris lindstroemii_ (Ostenfeld) =C1 L=F6ve and D. = L=F6ve. o _Senecio ogotorukensis_ Packer in Porsild and Cody (1980) is now _Packera ogotorukensis_ (Packer) =C1 L=F6ve and D. L=F6ve. o _Senecio pauciflorus_ Pursh in Porsild and Cody (1980) is now _Packera pauciflora_ (Pursh) =C1 L=F6ve and D. L=F6ve. o _Senecio pauperculus_ Michaux in Porsild and Cody (1980) is now _Packera paupercula_ (Michaux) =C1 L=F6ve and D. L=F6ve. o _Senecio yukonensis_ A.E. Porsild in Porsild and Cody (1980) is now _Tephroseris yukonensis_ (A.E. Porsild) Holub. o _Solidago canadensis_ L. var. _salebrosa_ (Piper) M. E. Jones in Porsild and Cody (1980) is now treated as _Solidago lepida_ de Candolle subsp. _lepida_ var. _salebrosa_ (Piper) Semple.=20 o _Solidago decumbens_ Greene in Porsild and Cody (1980) is now _Solidago simplex_ Kunth var. _simplex_. o _Spergularia marina_ (L.) Grisebach in Porsild and Cody (1980) is now called Spergularia salina J. Presl and C. Presl. o Thalictrum occidentale Gray. Western Meadow-Rue was reported for NT by Kartesz and Meacham (1999) on the basis of a specimen at DAO and the literature report of Scoggan (1978a). Male plants are difficult to = identify and the specimen from Fisherman Lake west of Fort Liard (9 June 1973, = Sheila Lamont FL-53, DAO 333723) is male. The filaments are mostly less then = 3.5 mm suggesting _Thalictrum venulosum_ Trelease, and on this basis, _T. occidentale_ is to be excluded from the flora.=20 Acknowledgements Dr. David Murray and Dr. Adolf Ceska provided useful comments.=20 Literature Cited Aiken, S.G., M.J.
