A century of research on heterostylous plants has passed since the publication of Charles Darwin's book "The Different Forms of Flowers on Plants of the Same Species" in 1877 summarizing his extensive observations and experiments on these complex breeding systems involving genetic polymorphisms of floral sex organs. Since then heterostylous plants have provided a rich source of material for evolutionary biologists and today they represent one of the classic research paradigms for approaches to the study of evolution and adaptation. The present book is the first modern and comprehensive accont of the subject. In 10 chapters it is concerned with the evolution, genetics, development, morphology, and adaptive significance of heterostyly. Broad syntheses of research on heterostyly as well as new theoretical ideas and experimental data are included.

This book is part of the TREDITION CLASSICS. It contains classical literature works from over two thousand years. Most of these titles have been out of print and off the bookstore shelves for decades. The book series is intended to preserve the cultural legacy and to promote the timeless works of classical literature. Readers of a TREDITION CLASSICS book support the mission to save many of the amazing works of world literature from oblivion. With this series, tredition intends to make thousands of international literature classics available in printed format again - worldwide.

“A survey of the botanical experimenting and theorizing that occupied Darwin’s golden years. . . . with expert evolutionary commentary.” —New York Review of Books For many people, Charles Darwin’s trip to Galapagos Islands on the Beagle, where he saw a biodiversity of birds, inspired him to write his theory of evolution. But this simplified narrative leaves out a major part of Darwin’s legacy. He published On the Origin of Species nearly thirty years after his voyages. And much of his life was spent experimenting with and observing plants. Darwin was a brilliant and revolutionary botanist whose observations and theories were far ahead of his time. With Darwin’s Most Wonderful Plants, biologist and gardening expert Ken Thompson restores this important aspect of Darwin’s biography while also delighting in the botanical world that captivated the famous scientist. We learn from Thompson how Darwin used plants to shape his most famous theory and then later how he used that theory to further push the boundaries of botanical knowledge. Both Thompson and Darwin share a love for our most wonderful plants and the remarkable secrets they can unlock. This book will instill that same joy in casual gardeners and botany aficionados alike. “In this quietly riveting study, plant biologist Ken Thompson reveals Charles Darwin as a botanical revolutionary.” —Nature “This is a fascinating insight into the scientist’s sheer delight in observing the minutiae of living organisms.” —Gardens Illustrated “Thompson revisits Darwin’s botany, showing us how insightful he was, where (rarely) he was wrong and the marvelous discoveries that have been made since. . . . Darwin himself would have loved this book.” —Jonathan Silvertown, author of Dinner with Darwin: Food, Drink, and Evolution

This 1862 publication describes the flower structure of orchids and their pollination to illustrate aspects of Darwin's evolutionary theory.

On the Origin of Species (or, more completely, On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life),[3] published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation of evolutionary biology.[4] Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.

A quorum of scientists offer reviews and results to celebrate the 150th anniversary of 'On The Various Contrivances By Which British And Foreign Orchids Are Fertilised By Insects, And On The Good Effects Of Intercrossing' (1862). Authors of the first ten chapters follow research on the pollination and breeding systems of the same orchid lineages that interested Darwin, including temperate and tropical species. Authors on the last two chapters provide information on the floral attractants and flowering systems of orchids using protocols and technologies unavailable during Darwin's lifetime.
