The illustrated encyclopedia of wild flowers and flora of the Americas : an authoritative guide to more than 750 wild flowers of the USA, Canada, Central and South America, beautifully illustrated with 1750 specially commissioned watercolours, photographs and maps

This lavishly illustrated and expert new reference work provides an invaluable guide to the flora of the Americas, from exotic orchids to familiar meadow blooms. It shows how to recognize the different parts of a plant, including petals, buds, fruit, seeds and stigma, and explains the role that each plays in the developing life of the plant. The diversity of leaf and flower form, shape, structure and habit are discussed, with advice on how to use these features to identify plants. The life cycle of a wild flower is clearly explained, from tiny seed to bud, open flower, pollination, seedhead and finally seed dispersal.
