With a claim to be the first work to document in detail the history of allelopathy, Willis s text provides an account of the concept of allelopathy as it has occurred through the course of botanical literature from the earliest recorded writings to the modern era. A great deal of information is presented here in a consolidated and accessible form for the first time. The book offers a unique insight into the historical factors which have influenced the popularity of allelopathy.

Allelopathy is a fascinating and perplexing topic that concerns the chemical interactions of plants. It has profound implications in agriculture and forestry where species are grown artificially in mixture, with no evolutionary history of co-existence. The topic of allelopathy is widely credited as commencing in 1937, when the term a ~allelopathya (TM) was coined by Molisch. However, the concept of allelopathy has been recorded since Greek and Roman times, became extremely controversial in the first half of the 19th century, and remains so today.

This book concerns a virtually unknown treatise by Justus Ludewig von Uslar, published in 1844, which emerges as the first book entirely devoted to the concept of allelopathy. The book provides the historical background to allelopathic knowledge, from antiquity to c. 1840. It also provides for the first time a biography of Justus Ludewig von Uslar, who is best known as the first Consul-General for Hannover in Mexico, and Director of the Mexican Company, a British venture mining company. In many ways von Uslar epitomises the tradition of the gentleman scientist of the 19th century. The book then offers a full translation into English of von Uslar's rare treatise, which foreshadows many ideas current in allelopathic research.

Allelopathy is the study of the chemical interactions of plants. This concept has been known since antiquity, and first appears unambiguously in written form in about 350 B.C. in the works of Theophrastus. This book gives a detailed account of the concept of allelopathy as it has occurred through the course of botanical literature from the earliest recorded writings to the modern era.

In the ancient world, the negative and positive interaction of plants was expressed within the framework of antipathy and sympathy of things. As such, antipathy and sympathy were more widely understood than generally appreciated, and indeed were assimilated in aspects of culture outside of botany and agriculture.

This book firstly addresses the question of what is allelopathy, as allelopathy is one of these unfortunate terms in ecology that has no unified definition. The book then examines the major episodes in the history of allelopathy: the writings from classical Greece and Rome; mediaeval Arabic, Indian and Chinese work; the advent of printing and promulgation of information in the 16th and 17th centuries; the 18th century and the theory of root excretion; the 19th century and the influence of A.P. de Candolle; the early 20th century and the work of Pickering and the USDA Bureau of Soils; and the years leading to the current era.

The work draws extensively on original sources, and consequently many of the assertions published in relation to the background of allelopathy, are shown to be incorrect, or at best very inadequate. There is a great deal of information presented, in a consolidated or accessible form, for the first time. The book endeavours to set the history of allelopathy within both a scientific and sociological context.
