For biologists, 2009 was an epochal year: the bicentennial of Charles Darwin’s birth and the 150th anniversary of the publication of a book now known simply as The Origin of Species. But for many botanists, Darwin’s true legacy starts with the 1862 publication of another volume: On the Various Contrivances by Which British and Foreign Orchids Are Fertilised by Insects and on the Good Effects of Intercrossing, or Fertilisation of Orchids. This slim but detailed book with the improbably long title was the first in a series of plant studies by Darwin that continues to serve as a global exemplar in the field of evolutionary botany. In Darwin’s Orchids, an international group of orchid biologists unites to celebrate and explore the continuum that stretches from Darwin’s groundbreaking orchid research to that of today. Mirroring the structure of Fertilisation of Orchids, Darwin’s Orchids investigates flowers from Darwin’s home in England, through the southern hemisphere, and on to North America and China as it seeks to address a set of questions first put forward by Darwin himself: What pollinates this particular type of orchid? How does its pollination mechanism work? Will an orchid self-pollinate or is an insect or other animal vector required? And how has this orchid’s lineage changed over time? Diverse in their colors, forms, aromas, and pollination schemes, orchids have long been considered ideal models for the study of plant evolution and conservation. Looking to the past, present, and future of botany, Darwin’s Orchids will be a vital addition to this tradition.

Recent studies have revealed remarkable complexity and diversity in orchid-pollinator relationships. These studies comprise a vast literature currently scattered in numerous, often obscure, journals and books. The Pollination Biology of North American Orchids brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators. This, the first of two volumes, furnishes a brief introduction to the general morphology of the orchid flower and the terminology used to describe orchid breeding systems and reproductive strategies. It treats the lady’s-slippers of genus Cypripedium, subfamily Cypripedioideae, and nine genera of the subfamily Orchidoideae, including the diverse rein orchids of genus Platanthera. The Pollination Biology of North American Orchids will be of interest to both regional and international audiences including: Researchers and students in this field of study who are currently required to search through the scattered literature to obtain the information gathered here. Researchers and students in related fields with an interest in the co-evolution of plants and insects. Conservation specialists who need to understand both the details of orchid reproduction and the identity of primary pollinators in order to properly manage the land for both. Orchid breeders who require accurate and current information on orchid breeding systems. General readers with an interest in orchid biology. Charles Argue, Ph.D., is a plant biologist at the University of Minnesota specializing in the study of pollen grains. His articles have appeared in numerous journals including the American Journal of Botany, International Journal of Plant Sciences (formerly Botanical Gazette), Botany (formerly Canadian Journal of Botany), Grana, Pollen et Spores, North American Native Orchid Journal, The Native Orchid Conference Journal, Fremontia, and as chapters in a number of books.

There are few other structures in nature from which evolution has generated such wide diversity as the flower or inflorescence, and this diversity is commonly attributed to the influence of their animal visitors. By outsourcing their mate choice to pollinators, plants have left themselves - and especially their flowers - subject to the selective forces imposed by the behaviour, cognition and perception of the pollinators that serve them. The orchids provide some of the most remarkable and extreme examples of adaptations to specific animal pollinators. Perhaps one of the most peculiar of these strategies is sexual deception, whereby male insects are lured to the flower by mimicry of the female sex pheromone. This seemingly unlikely strategy has evolved multiple times independently on different continents in different parts of the orchid phylogeny which raises the question of what adaptive advantages might underlie such a strategy. This multidisciplinary thesis studies gene flow and pollinator behaviour in two sympatric sexually deceptive orchids in the genus Chiloglottis. The two species attract their specific wasp pollinators through emission of distinct species - specific semiochemicals. Since floral volatiles play a pre-eminent role in pollinator attraction, Chiloglottis provides an excellent case study for examining the interaction between floral volatile chemistry, pollinator behaviour and the evolutionary dynamics of populations. The thesis begins with a review of floral volatiles and their role in pollinator attraction and plant speciation. The literature is used to develop a research framework of six testable hypotheses under which we might productively explore the influence of floral volatiles on plant evolution. These hypotheses are then explored in the study system over the following chapters. A study of pollinator specificity, neutral genetic differentiation and floral chemistry demonstrates that the chemical mimicry crucial to sexual deception is responsible for reproductive isolation and potentially even speciation. Mating system and paternity analysis provide the first genetic evidence for multiple paternity in orchid broods. Extensive outcrossing is found to predominate and paternity assignment shows evidence for long distance pollen flow supporting the hypothesis that sexual deception promotes outcrossing and so minimizes the potentially deleterious effects of selfing. Lastly, an innovative new method is developed for tracking wasps in the field. Application of this technique to a population of orchid-pollinating wasps reveals detailed information about their movement and mating behaviour. The findings support the conclusion that sexual deception is a superb adaptive solution to the problem flowers face of simultaneously attracting pollinators and persuading them to leave quickly.

The male thynnine wasp's extreme sexual enthusiasm is crucial to reproduction of hammer orchids in the wild. Hammer orchids have co-evolved to produce odors identical to those manufactured by female thynnine wasps. The male wasp's superb sensitivity to the scent of his female mate is the basis for the hammer orchid's deceit--in effect, orchids exploit the male insect's highly adaptive sense of smell for their own propagation. While pollinating orchids is a waste of time, and thus a maladaptive activity for a wasp, his mistake comes about because he must react quickly whenever he senses a possible mate nearby. Alcock suggests that, "for insects, he who hesitates is lost, although perhaps it would be better to say that he who hesitates often loses a chance to pass on his genes." This book abounds with clever explanations for how these exceptionally complex flowers came to be shaped as they are. The reader can explore many aspects of orchid biology and history ranging from how some species avoid inbreeding, to the origins of orchids from an ancestor that belonged to the asparagus family. Examining each component of an orchid's flower, Alcock explains how the various parts work together to produce the plant's minute offspring. Each element of an orchid, as quirky as it may seem, is biologically significant, bearing the imprint of natural selection. Readers can share in the delight that Darwin and all other orchid enthusiasts have felt in making sense of even the smallest of details of these most wonderful plants.

This book provides a first hand and complete information on orchid biotechnology for orchid lovers, graduate students, researchers and industry growers. It contains comprehensive genomics and transcriptomics data, and a thorough discussion of the molecular mechanism of orchid floral morphogenesis. The contributors to the book are all orchid enthusiasts with more than 20 years' experience in the field.With more than 25,000 species, orchids are the most species-rich of all angiosperm families. They show wide diversity of epiphytic and terrestrial growth forms and have successfully colonized almost every habitat on earth. Orchids are fantastic for their spectacular flowers with highly evolved petal, labellum, and fused androecium and gynoecium, gynostemium, to attract pollinators for effective pollination. In addition, orchids have attracted the interest of many evolutionary biologists due to their highly specialized evolution and adaptation strategies.Orchid Biotechnology III covers the most update knowledge of orchid biotechnology research on Phalaenopsis, Oncidium, Cymbidium, Anoectohilus, Paphiopedilum, and Erycina pusilla. It will provide graduate students, researchers, orchid lovers and breeders with an opportunity to understand the mechanism why the orchids are so mysterious and spectacular. Hopefully, this information will be helpful for breeders to enhance orchid breeding and create even more elegant and grace flowers.
