Book Description
The Botrychiaceae is a family of small, inconspicuous, perennial ferns with five genera, three of which are found in Alberta. This publication begins with an overview of the characteristics of this family, the history of its taxonomy, Botrychiaceae habitats in Alberta & priorities for conservation, the life history of the Botrychiaceae, and fossils of the Botrychiaceae discovered in Alberta. The main section presents an identification key & descriptions of 19 Botrychiaceae found in Alberta. The descriptions include information on habitat, geographic distribution, rarity status, and chromosome number if known.

Book Description
Moonworts, or ferns belonging to the genus Botrychium, are the largest group of rare ferns in Alberta. This report synthesizes the data collected in a project to identify potential threats to these species and their habitats in Alberta. The objectives of the project were to revisit known populations of rare Botrychium species, search for new populations, document the characteristics of their habitats, and evaluate potential threats to their security. The report begins with a review of the research methods used, a summary of moonwort habitat characteristics & conservation strategies, and presents management recommendations for eight general regions that were visited during the 2001 field season. Species of concern in each region are identified.

Book Description
"Packer and Gould have provided an invaluable service for anyone interested in western North American botany by creating a simple, user-friendly and portable key to the Alberta species found in the 30-volume set of Flora of North America. Designed to be carried into the field for handy reference and use, this work incorporates the new names and taxonomical understandings that have accumulated over the years. Part 1 of what will be a three-volume set contains the up-to-date classification of the ferns, fern allies, gymnosperms, and monocots found in Alberta according to the latest taxonomic findings."--

Book Description
This book constitutes a unique, encyclopedic reference work that systematizes and categorizes for the first time in such comprehensive fashion all known fern spores. The dominant feature of the work are the over 350 plates of electron micrographs showing the morphological characteristics of typical representatives of each spore type. The purpose of the book is to provide a complete survey of the available data on the fine structure and composition, development, and evolu- tionary significance of different types of spore walls, which have proven resistant to fossilization throughout geological ages. The classification system developed by the authors as the result of many years of research will be a point of reference, if not "the" systematic basis, for all future publication on the subject. The book will be of great interest to all botanists and evolutionary biologists working with spores and/or ferns, but it will also be of major importance to paleobotanists, palynologists, stratigraphers, and exploration geologists, since the focus of this treatise is on spores as highly adapted and longlived reproductive forms.
