Original studies address key aspects of the conservation and biodiversity of plants. Articles are all peer-reviewed primary research papers, contributed by leading biodiversity researchers from around the world. Collectively, these articles provide a snapshot of the major issues and activities in global plant conservation. Many of the articles can serve as excellent case studies for courses in ecology, restoration, biodiversity, and conservation.

A unique addition to the botanical literature, this book presents the flora of China in its astonishing diversity.

Written as a reference to be used within University, Departmental, Public, Institutional, Herbaria, and Arboreta libraries, this book provides the first starting point for better access to data on medicinal and poisonous plants. Following on the success of the author's CRC World Dictionary of Plant Names and the CRC World Dictionary of Grasses, the author provides the names of thousands of genera and species of economically important plants. It serves as an indispensable time-saving guide for all those involved with plants in medicine, food, and cultural practices as it draws on a tremendous range of primary and secondary sources. This authoritative lexicon is much more than a dictionary. It includes historical and linguistic information on botany and medicine throughout each volume.
