The Ecological Relations of Roots (1919) is a book by John Ernest Weaver (1884 – 1966),  an American biologist and prairie ecologist. During his life, Weaver published a series of books on the relationship between plant species, their climate and the specific soils they inhabit. This book focuses on the roots of native plants in desert climates, featuring more than 140 species chosen after the examination of more than 1000 individual plants across different territories. 

The text is beautifully illustrated, with detailed section drawings depicting the relationship between the plants emerging over the soil and its underneath root system. The drawings were either made from photographs or at the same time as the root was excavated featuring precise measurements. 

Series of grids and scales illustrate very efficiently the varying proportions of the different species. For Weaver, one of the main aims of this publication is to understand the root distribution to ultimately find “a more intelligent solution to the ecological problems of grazing.”

In the last section of the publication, a series of photographs show the plants and their roots over a black background. While both illustrations and photos are employed for scientific purpose, they reveal an underlying aesthetic pleasure in their composition and execution.

In the introduction of the book, John Ernest Weaver thanks Miss Annie Mogensen and Mrs F. C. Jean for their assistance in drawing many of the root systems…

As we dig it, we might spare a thought for Hieronymus Bock; he died on this date in 1554. A Lutheran minister, physician, and botanist, he began the transition from medieval to modern scientific botany by arranging and naming (over 700) plants by their relation or resemblance. His was the first documented use of the modern word “Riesling” (in 1552).
