VASCAN, the database of vascular plants of Canada

VASCAN is a comprehensive list of the vascular plants of Canada, Greenland (Denmark) and Saint Pierre and Miquelon (France). For each species, sub-species and variety, VASCAN provides the accepted scientific name (in Latin), accepted vernacular name in French and English, synonyms or alternative names, plant distribution status (native, introduced, etc.) and habit of the plant (tree, shrub, herb or vine). VASCAN also includes a distribution map by province or territory and can generate lists of taxa according to various criteria (distribution, habit, etc.). VASCAN data can be downloaded.
