In the summer of 1891, Per Axel Rydberg and his assistant, Julius Hjalmar Flodman, collected plants in western Nebraska for the United States Department of Agriculture. They collected many first-records for Nebraska as well as some that became type specimens of Rydberg's and other botanists' names. In the following autumn and winter, Ryd-berg made a detailed, typewritten, carbon copied 35-page Report and 37-page List of specimens from that trip; one carbon copy is in the Bessey Herbarium (NEB) at the University of Nebraska-Lincoln. It is these documents that we present here, extensively annotated with our geographic clarifications, original and updated nomenclature, and citations of specimens in NEB and elsewhere.
Rydberg, one of the most productive scientists at the New York Botanical Garden during its first century, possessed a wealth of knowledge on the flora of the Rocky Mountain region & the Great Plains of North America. This Memoir celebrates the man & his deeds & includes a 215- item bibliography.

"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.

This volume, the fourth in a series of books that collectively update and expand P.A. Johnsgard's 1975 The Waterfowl of North America, summarizes research findings on this economically and ecologically important group of waterfowl. The volume includes the mostly tropical perching duck tribe Cairinini, of which two species, the muscovy duck and the wood duck, are representatives. Both species are adapted for foraging on the water surface, mostly on plant materials, but typically perch in trees and nest in elevated tree cavities or other elevated recesses. This volume also includes the dabbling, or surface-feeding, duck tribe Anatini, a large assemblage of duck species that mainly forage on the water surface but nest on the ground, or only very rarely in elevated locations. Of this tribe, 12 species that regularly breed in North America are included, among them such familiar species as mallards, wigeons, pintails, and teal. Descriptive accounts of the distributions, populations, ecologies, social-sexual behaviors, and breeding biology of all these species are provided, together with distribution maps. Five additional Eurasian and West Indian species have been reported several times in North America; these have been included with more abbreviated accounts, but all 17 species are illustrated by drawings, photographs, or both. The text includes about 84,000 words and contains more than 1,000 references. There are also 12 distribution maps, 21 drawings, 28 photographic plates, and 58 anatomical or behavioral sketches.
This remarkable history encompasses not only the achievements of the early inventors and astronomers but also the less frequently recounted stories of the instrument makers and of the actual instruments. A model of unsurpassed, comprehensive scholarship, this volume covers many fields, including professional and amateur astronomy. 196 black-and-white illustrations.
Containing thousands of entries of both vernacular and scientific names of Great Plains plants, the literature that informs this exhaustive listing spans nearly 300 years. Author Elaine Nowick has drawn from sources as diverse as Linnaeus, Lewis and Clark, and local university extension publications to compile the gamut of practical, and often fanciful, common plant names used over the years. Each common name is accompanied by a definitive scientific name with references and authority information. Interspersed with scientifically-correct botanical line drawings, the entries are written in standard ICBN format, making this a useful volume for scholars as well as lay enthusiasts alike. Volume 2 indexes the scientific names of those species, followed by listings of all the common names applied to them. Both volumes refer the common and scientific names back to a list of 190 pertinent authoritative sources.
