Vascular Flora of Illinois

by Robert H. Mohlenbrock

2002 · SIU Press

The first flora of Illinois was prepared in 1846 by Dr. Samuel B. Mead, a physician from Augusta, Illinois. Between 1846 and 1963, several people published plant lists and floras for various parts of Illinois. In 1975, Robert H. Mohlenbrock published his first edition of Guide to the Vascular Flora of Illinois, followed by a second expanded and revised edition in 1986. This latest Vascular Flora of Illinois includes over thirty-two hundred species, an increase of almost three hundred since 1986. In addition, for the first time, taxa below the rank of species are recognized and may be identified by keys. Investigating seldom-visited patches of prairies, wetlands, and forested canyons, Mohlenbrock has added several native species to this flora. And while there has been extensive exploration for plants, Mohlenbrock has also researched the herbaria in an attempt to verify previous reports of records of Illinois plants. Because of a reinterpretation of existing genera, the number of genera of Illinois plants has increased markedly. Recent biosystematic techniques have begun to substantiate the genera that botanists such as John Kunkel Small, Per Axel Rydberg, and Edmund C. Greene proposed nearly a century ago. The sequence of groups in this book is ferns, conifers, and flowering plants, with dicotyledons given before monocotyledons. Within each group, the families are arranged alphabetically, as are the genera within each family and the species within each genus. For each taxon recognized in this book, Mohlenbrock gives a common name if one is generally used in Illinois. He follows this by an indication of flowering time for flowering plants and of spore-production time for ferns and their relatives. He also provides a habitat statement and a general comment on distribution in Illinois for each taxon. Synonyms for some other scientific names used previously for a taxon appear in italics. This book contains indexes both for common names and for family and genus names.

Junipers of the World: The Genus Juniperus, 4th Edition

by Dr. Robert P. Adams

2014 · Trafford Publishing

The Junipers of the World contains a synthesis of data on evolution by examining: Geographic Variation: Pan-Arctic variation in Juniperus communis, etc. Speciation in sections of the genus: Species concepts, Speciation in Juniperus section Juniperus, etc. In addition, Keys to Juniperus are provided by region: Eastern Hemisphere, Europe (including Azores, Canary Islands, Asia Minor and Africa), Central Asia (Turkmenistan to western Himalayas), China, Far East (Japan, Korea, Sakhalin Island, Taiwan), Western Hemisphere, Continental North America, United States and Canada, Mexico and Guatemala, and the Caribbean. Also included are Species' Descriptions, Distribution Maps and Plant Photos, and chapters on Hybridization, Ecology, Cultivated Junipers, Commercial uses of leaf and wood oils of Juniperus, a Cross Indexed Synonymy of Juniperus, and Tables on the Leaf essential oils by species in sections. This book supplements the web site www.juniperus.org and the reader will find literature citations and a detailed discussion of data that is not present on the web site. "The Junipers of the World is now the authoritative reference for Juniperus" "Prof. Adams has presented arguments for the recognition of species and varieties by showing the data analyses that led to taxonomic decisions. This is one of the few treatments that really integrates data and the reasoning behind taxonomic decisions. In addition, Prof. Adams is candid in admitting that the recognition of some taxa are not well supported and deserve additional study." "An essential reference book that will be useful for herbaria, museums, wildlife biologists, Range scientist, foresters, ecologists and all who are involved in identification and study of Juniperus species."

2009 · SIU Press

This second edition updates the status of the Polygonaceae, Hamamelidaceae, Platanaceae, Fagaceae, Betulaceae, and Corylaceae in Illinois. Each of the newly discovered species has been added and is fully illustrated. Updated nomenclature as well as Illinois distributional data are included for each species. In addition to the fourteen new plant illustrations, the appendix contains new information on the descriptions and the geographical locations of plants in the first edition, and revised identification keys.
