These four volumes were originally published in the years between 1957 and 1965. Their purpose was the accurate identification of all British plants, including a large number of commonly grown related garden plants and well-established aliens. In addition, invaluable information concerning the ecology, geographical distribution, evolutionary history and agricultural significance of the plants is provided. These volumes will still be of particular interest and relevance to amateur botanists and anyone wishing to know more about British plant life.
