17 December 2014 TAXACEAE (Yew Family) __ Taxus canadensis Canada Yew FIELD CHECKLIST OF THE VASCULAR PLANTS OF JOKERS HILL King Township, Regional Municipality of York PINACEAE (Pine Family) C.S Blaney and P.M. Kotanen* __ Larix laricina Tamarack *Correspondence author: __ Picea glauca White Spruce Department of Ecology & Evolutionary Biology __ Pinus strobus White Pine University of Toronto at Mississauga __ Pinus sylvestris Scots Pine 3359 Mississauga Road North __ Tsuga canadensis Eastern Hemlock Mississauga, ON Canada CUPRESSACEAE (Cypress Family) e-mail: [email protected] __ Juniperus communis Common Juniper __ Juniperus virginiana Eastern Red Cedar The following list is based on observations and collections by the authors between 1997 and 1999, __ Thuja occidentalis Eastern White Cedar with later additions by numerous observers. It includes all species known to be growing outside of cultivation within the Jokers Hill property. Also listed are native species found in land adjacent to the TYPHACEAE (Cat-tail Family) Jokers Hill property, but not yet found on the site (scientific name preceded by "*" - 13 species). A __ Typha angustifolia Narrow-leaved Cat-tail total of 631 taxa (species and hybrids) are listed; 450 taxa are considered native to Jokers Hill (those __ Typha latifolia Common Cat-tail listed in bold typeface) and 181 are considered non-native (listed in regular typeface). Determining native versus non-native status required a few rather arbitrary judgements. SPARGANIACEAE (Bur-reed Family) __ Sparganium chlorocarpum Green Bur-reed Several people assisted in the preparation of this list. P. Ball of the University of Toronto at Mississauga and A. Reznicek of the University of Michigan assisted with a number of difficult POTAMOGETONACEAE (Pondweed Family) identifications, especially in the Cyperaceae. T. Dickinson and J. Bull of the Royal Ontario Museum __ Potamogeton pectinatus Sago Pondweed identified the Crataegus specimens. Warren Wagner at the United States National Herbarium identified Oenothera biennis, Oenothera parviflora, and Oenothera villosa subsp. villosa. Peter NAJADACEAE (Naiad Family) Kotanen formatted the document for the world wide web __ Najas flexilis Flexible Naiad (http://www.zoo.utoronto.ca/jokershill/jhplants.html). Jarmo Jalava of the Ontario Natural Heritage Information Center compiled the pre-existing information on the site. ALISMATACEAE (Water-plantain Family) __ Alisma plantago-aquatica Water-plantain (A. triviale) Taxonomy, with only a few exceptions, follows Morton and Venn (1990). Where widely used __ Sagittaria latifolia Common Arrowhead synonyms or other potentially confusing alternate binomials exist, these are listed below the species' scientific name. As there are no standard English names for plant species, common names have been POACEAE (Grass Family) taken from a variety of sources. Although we have visited all parts of the property looking for __ Agrostis gigantea Redtop plants, many additional species will still be found with further field work. Information on any __ Agrostis scabra Tickle Grass (A. hyemalis) additional species (preferably with specimens) or other comments on the list would be welcomed by __ Agrostis stolonifera Creeping Bent Grass the authors. __ Alopecurus aequalis Short-awn Foxtail __ Avena sativa Oats ------------------------------------------------------------------------------------------------------------------------ __ *Brachyeletrum erectum Bearded Shorthusk EQUISETACEAE (Horsetail Family) __ Bromus ciliatus Fringed Brome __ Equisetum arvense Field Horsetail __ Bromus inermis Awnless Brome __ Equisetum fluviatile Water Horsetail __ Calamagrostis canadensis Canada Bluejoint __ Equisetum hyemale Rough Horsetail __ Cinna latifolia Drooping Woodreed __ Equisetum pratense Meadow Horsetail __ Dactylis glomerata Orchard Grass __ Equisetum scirpoides Dwarf Scouring-rush __ Danthonia spicata Poverty Grass __ Equisetum sylvaticum Woodland Horsetail __ Digitaria ischaemum Smooth Crab-grass __ Equisetum variegatum Variegated Horsetail __ Digitaria sanguinalis Large Crab-grass __ Echinochloa crusgalli Barnyard Grass LYCOPODIACEAE (Club-moss Family) __ Echinochloa wiegandii Western Barnyard Grass __ Lycopodium clavatum Staghorn Clubmoss __ Elymus repens Quack Grass (Agropyron repens) __ Lycopodium digitatum Running Ground-cedar (L. flabelliforme) __ Elymus virginicus Virginia Wild Rye __ Lycopodium lucidulum Shining Clubmoss __ Festuca arundinacea Fall Fescue (F. elatior, in part) __ Lycopodium obscurum (s.st.)
