Originally published in 1913, as part of the Cambridge Nature Study Series, this book was written by the renowned Irish botanist and author Robert Lloyd Praeger (1865–1953). Intended for the younger reader, it provides an introduction to the ways in which weeds grow and spread, also showing how 'the function of different parts of plants, and indeed all the lessons of elementary botany, can be studied to full advantage among our common weeds'. Numerous illustrative figures are included. This is a highly accessible volume that will be of value to anyone with an interest in the writings of Praeger, the history of botany and books for children.
