Plant Variation and Evolution

<p>Natural populations of plants show intricate patterns of variation. European botanists of the eighteenth and nineteenth centuries used this variation to classify different "kinds" into a hierachy of family, genus, and species. Although useful, these classifications were based on a belief in the fixity of species and the static patterns of variation. Darwin's theory of evolution changed this view; populations and species varied in time and space and were part of a continuing process of evolution. The development of molecular techniques has transformed our understanding of microevolution and the evolutionary history of the flowering plants. This revised, extended edition describes the historical background to plant variation studies and considers the remarkable insights that molecular biology has recently given into the processes of evolution in populations of cultivated, wild and weedy species; the threats of extinction faced by many endangered species and the wider evolutionary history of the flowering plants as revealed by cladistic methods.</p>

<p>This flora, published in 1964, was the first comprehensive account of Cambridgeshire's plants since Babington's of 1860. Based on records to the end of 1962, it details 1509 species. These comprise 27 pteridophytes, 3 gymnosperms, 1223 angiosperms and 256 bryophytes. The following information is provided for each of the species: scientific name; well-known vernacular name, if any; first known record of the plant in the county; synonyms; habitat; notes on rare, difficult or interesting species; distribution by OS grid reference numbers. The introduction examines local topography, climate, the main geological areas and vegetation types, together with a history of botanical investigation in the county. Important localities are noted, highlighting key species that could then be found. Botanists, conservationists and naturalists will find this historic flora provides a valuable baseline for contemporary studies, including those focusing on biodiversity, extinction or the effects of climate change.</p>
