Published posthumously, this volume reflects renowned botanist Arthur Cronquist's long-time interest in the Asterales & completes the work on the Asteridae begun in Volume Four.

This volume covers a great many of the most difficult families found in the flora of the intermountain region. The largest sections of this volume are dedicated to four families: Polemoniaceae, Hydrophyllaceae, Boraginaceae, & Scrophulariaceae.

"The taxonomic treatments for Intermountain Flora were published between 1972 and 2012 in eight parts, volumes 1, 2A, 2B, 3A, 3B, 4, 5, and 6. Included in this, the ninth part of the series, are miscellany that did not fit conveniently in the volumes with taxonomic treatments. For the past three years, we have informally referred to this volume as the 'Supplement, ' but because of the mixed nature of the contents, we have decided to call it volume 7, 'the potpourri volume.' It contains acknowledgments of individuals and institutions; keys to all families; an alphabetical list of families with volume numbers and authors; a history of the project; biographies of Bobbi Angell, Rupert C. Barneby, Arthur Cronquist, Arthur H. Holmgren, Noel H. Holmgren, Patricia K. Holmgren, Jeanne R. Janish, Bassett Maguire, James L. Reveal, and Arnold (Jerry) Tiehm; photographs of authors, artists, and plant collectors of the Intermountain West; an update to the 1984 treatment of Intermountain Penstemon published in volume 4; a list of general references and online resources; an expanded glossary; a list of nomenclatural innovations, typifications, and chromosome data; an index to people whose photographs appear in Intermountain Flora; and a cumulative index for all seven volumes. The eight earlier volumes include descriptions of 146 vascular plant families (plus three cultivated families [Aquifoliaceae, Thymelaeaceae, and Tropaeolaceae] incidentally mentioned), 898 genera, 3847 species, and 1571 varieties. An additional 426 cultivated species and 551 extralimital taxa are treated in keys and/or discussions. The five largest families are Asteraceae (volume 5), Poaceae (volume 6), Fabaceae (volume 3B), Brassicaceae (volume 2B), and Scrophulariaceae (volume 4). The five largest genera are Astragalus (volume 3B), Eriogonom (volume 2A), Penstemon (volume 4), Carex (volume 6), and Erigeron (volume 5). The four authors (Barneby, Cronquist, Noel and Patricia Holmgren) based at the New York Botanical Garden prepared manuscript for 82% of the 3867 pages in the volumes with taxonomic treatments. In addition, Noel did the page composition and layout of illustrations, and Pat edited the manuscripts and compiled the index. In this volume, Noel designed the photo albums and prepared the keys to families, the history, the biographies of authors, artists, and Maguire, the Penstemon update, and the glossary, and Pat compiled the list of families and the indices, gathered photographs of the artists, authors, and collectors, and prepared the biography of Tiehm."--Introduction to volume 7.

Originally published by the U.S. Department of Transportation's Federal Highway Administration (FHWA), Office of Natural Environment to promote the planting and care of native plants along highway rights-of-way, this unique handbook provides managers of roadsides and adjacent lands with the information and background they need to make site-specific decisions about what kinds of native plants to use, and addresses basic techniques and misconceptions about using native plants. It brings together in a single volume a vast array of detailed information that has, until now, been scattered and difficult to find.The book opens with eighteen short essays on principles of ecological restoration and management from leading experts in the field including Reed F. Noss, J. Baird Callicott, Peggy Olwell, and Evelyn Howell. Following that is the heart of the book, more than 500 pages of comprehensive state-by-state listings that offer: a color map for each state with natural vegetations zones clearly marked comprehensive lists of native plants, broken down by type of plant (grasses, forbs, trees, etc.) and including both scientific and common names, with each list having been verified for completeness and accuracy by the state's natural heritage program contact names, addresses, and phone numbers for obtaining current information on invasive and noxious species to be avoided resources for more information, including contact names and addresses for local experts in each state The appendix adds definitions, bibliography, and policy citations to clarify any debates about the purpose and the direction of the use of native plants on roadsides.Roadside Use of Native Plants is a one-of-a-kind reference whose utility extends far beyond the roadside, offering a toolbox for a new aesthetic that can be applied to all kinds of public and private land. It can help lead the way to a cost-effective ecological approach to managing human-designed landscapes, and is an essential book for anyone interested in establishing or restoring native vegetation.
