  • Norris Whiston’s Index & Keys for Trees & Shrubs of the Maritimes by Todd Boland (2012)
    Norris has prepared a detailed index and a variety of keys to aid in use of Todd Boland’s illustrated guide to over 230 native and introduced species of trees and shrubs in the Maritimes. Norris suggests attaching the 6 pages to the inside of the front cover. The index provides a quick reference to distinguishing different species within a taxon, e.g., under “hawthorne” he cites: hawthorn: 132 (6 or 8 lobes with large teeth); English hawthorn 134 (3-7 deep lobes); heather: woolly 40 (yellow); Scottish 41; pine barren golden 34;. His keys group species by Leaf Types, Flower Types, Seeds, Fragrance, Fall Colours, Bark and Twigs. NS Wild Flower folk who gave it a test-run found it very user-friendly.

  • A list of vascular plant species in the Nova Scotia flora

  • Atlantic Canada Conservation Data Centre: Species Ranks

Lists are organized by province and by taxonomic group. Newfoundland and Labrador are treated separately for ecological reasons.” For N.S. there are close to 2000 native and naturalized species listed; approx. 38% are naturalized species.
  • NatureServe Explorer
    is “An online encyclopedia of plants, animals, and ecosystems of the U.S. and Canada.. an authoritative source for information on more than 70,000 plants, animals, and ecosystems of the United States and Canada.

  • The Plant List
    The Plant List is a working list of all known plant species. Version 1 aims to be comprehensive for species of Vascular plant (flowering plants, conifers, ferns and their allies) and of Bryophytes (mosses and liverworts). Collaboration between the Royal Botanic Gardens, Kew and Missouri Botanical Garden enabled the creation of The Plant List by combining multiple checklist data sets held by these institutions and other collaborators. The Plant List provides the Accepted Latin name for most species, with links to all Synonyms by which that species has been known. It also includes Unresolved names for which the contributing data sources did not contain sufficient evidence to decide whether they were Accepted or Synonyms.
  • Angiosperm Phylogeny Website
    This website is maintained by Peter F. Stevens, Curator of the Missouri Botanical Gardens. Stevens is one of the Angiosperm Phylogeny Group authors of the initial APG classification (1998) and its successor, APG II (2002). “At the web site, set up with Hilary Davis’s help, I marry morphological, anatomical and chemical variation patterns with the most recent well-supported estimates of phylogeny. The variation is placed in a strictly hierarchical context as far as is possible. The site is updated every six months or so, and generally follows the Angiosperm Phylogeny GroupsÕs consensus classification [APGIII], albeit a little more elaborated as the site can be kept more current both in terms of phylogenetic hypotheses and morphology..”
