Packed with more than 4,000 alphabetically arranged entries, A Dictionary of Plant Sciences is an essential resource for students of botany, plant sciences and plant biology, environmental science, and horticulture, as well as for amateur botanists and naturalists, and for the general reader with an interest in botany. Revised and updated to account for recent research, and with over 250 completely new entries, the third edition of this dictionary offers broad coverage of all aspects related to the field of plant sciences, including biochemistry, plant physiology, cytology, ecology, genetics, evolution, biogeography, earth history, and earth sciences. New entries such as evo-devo, sister relationship, polytomy , and parallel sequencing make this the most up-to-date and comprehensive dictionary available and forty-seven line drawings add to the clarity and accessibility of the text. In addition, useful appendices (The Universal Genetic Code, The Geologic Time-Scale, SI Units, Plant Classification, Fungi Classification) and a dedicated companion website (featuring links to relevant online resources) support and enhance the coverage found in the paperback.
