- Norris Whiston’s Fruit, Seeds, and Animals
A 4 page document, 3 columns with 4 items per column, each illustrated with a colour photo by Norris and divided into categories (e.g., Conical or Upright Drupes Clusters, Hanging Drupe / Berry Chains) to facilitate quick ID. The text provides info on the use of fruits and seeds by animals. May be downloaded for individual use.
- 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.

- Integrated Taxonomic Information System (ITIS) Canada: Biological Name Search
Provided by the Canadian Biodiversity Information Facility. Enter a scientific or vernacular name to view the taxonomic hierarchy (Family, Order..) for a species and its “Taxonomic Credibility Rating“. It is a work in progress: see Some of the problems that CBIF will address.
- A list of vascular plant species in the Nova Scotia flora
A page on this website. The list was generated from Wild Species 2005: From the Status of Species in Canada Overview using the General Status Search Tool. it’s a place to start rather than an authoritative list.
- Atlantic Canada Conservation Data Centre: Species Ranks
“The Atlantic CDC maintains comprehensive lists of plant and animal species, with a rarity rank and legal status for eachÉThrough the links you can access lists of species, including rare species, for each Atlantic province. 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. Explorer includes particularly in-depth coverage for rare and endangered species.” The NatureServe Conservation Status of a species is given for individual states and provinces
- 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..”

- International Plant Names Index
“The International Plant Names Index (IPNI) is a database of the names and associated basic bibliographical details of all seed plants, ferns and fern allies. Its goal is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names. IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and the Australian National Herbarium.”

All of the nomenclatural, bibliographic, and specimen data accumulated in MBG’s electronic databases during the past 25 years are publicly available here. This system has over 1.2 million scientific names and 4.0 million specimen records. “
