This dictionary of botany draws on information from the Oxford Dictionary of Natural History and expands it to include a wide coverage of topics such as biochemistry, plant physiology, cytology, ecology, genetics, evolution, bio-geography, earth history, and the earth sciences. There is also worldwide coverage of taxonomic groups: one-third of the entries are devoted to taxa, from bacteria and fungi to the main groups of flowering and non-flowering plants.

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories. It includes names, plant symbols, checklists, distributional data, species abstracts, characteristics, images, crop information, automated tools, onward Web links, and references. This information primarily promotes land conservation in the United States and its territories, but academic, educational, and general use is encouraged. PLANTS reduces government spending by minimizing duplication and making information exchange possible across agencies and disciplines.
