Philosophia Botanica (The Science of Botany), by Carl Linnaeus, was originally published in Latin in Stockholm and Amsterdam in 1751. It is a greatly expanded revision of his Fundamenta Botanica (Foundations of Botany) of 1736, summarizing his work on the classification and taxonomy of plantswhile adding substantial new material. The book represents a critical stage in the evolution of binomial nomenclature, with a single word to describe the genus and another for the species. Special importance is attached to accurate description of the parts of plants, and to the correct use of technical terms. There are also explanationsof the effects of soil and climatic conditions on plant growth. The book includes 10 original engravings, with 167 figures showing the shapes of leaves and other parts of the plant, and 6 short memoranda describing Linnaeus' botanical excursions, detailing his ideas for garden and herbarium construction, and outlining what is required of a botanist and hispupils. There are also indexes of technical terms, genera, and subjects. The first full English translation of this classic work since 1775, this beautiful book will be highly attractive to botanists and all those interested in the history of science.
