This exhaustively researched project brings together for the first time a complete listing of Alberta's rare vascular plants with detailed plant descriptions, habitat information and notes of special interest. Accompanied by numerous colour photographs, B&W illustrations and frequency maps, this text is essential for naturalists, botanists, students, and others interested in the flora of Alberta.

This list was compiled to promote awareness of rare plants in Canada's flora, and also to promote awareness of their ecosystems and the need to preserve them. The list includes all native taxa, above the rank of form, that are rare in each of the provinces and/or territories in which they occur. Hybrids and naturalized species are not included. Information given for each includes scientific name and authority, synonyms, family name, references, endemism, nature conservancy rank, Canadian priority, and Committee on the Status of Endangered Wildlife in Canada status. Plants are also listed by family, endemic, province or territory, and priority.
