As lushly illustrated as it is informative, this book reveals the immense variation found among members of this extraordinary genus.

Pictorial Guide is a new and comprehensive photographic atlas with nearly 1000 new color photographs illustrating most of the wild species of Passiflora known to science. Bursting with a wealth of images of exotic species taken in the wild as well as those that most gardeners are likely to encounter in the horticultural trade, this book showcases elegant blossoms of these fantastic tropical vines, shrubs, and trees and captures the imagination with spectacular colors, dramatic forms, and amazing variations. Comprehensive and scientifically accurate, this survey of the genus Passiflora is the first reference book on passionflowers published in more than 15 years and the only pictorial reference guide of its kind. The splendor of more than 280 wild passionflower species as they appear in nature, as well as 11 hybrids, represents the culmination of the author's 30-year fascination with this exotic genus and his more than 120 trips to Costa Rica and Ecuador observing and collecting the vines. Simple to use, the species are arranged alphabetically. The geographic range is given for every species, based on the latest verified identifications from world databases. At least one flower is shown for each entry, and very importantly, unlike other guides, a photograph of a leaf or often a fruit is shown. The author's special accumulated knowledge of which specific butterfly feeds on which kind of plant is shared through notes under the respective host plants. A colorful appendix to the coevolved Heliconius butterflies rounds out the volume. The author Ronald Boender is an expert on passionflower butterflies and a pioneer in breeding and exhibiting butterflies. In 1988 he developed and opened the first commercial butterfly farm and public exhibition in the Americas, called Butterfly World, in Coconut Creek, near Fort Lauderdale, Florida. Quickly becoming a renowned expert on growing passionflowers, he developed the largest collection of species and has contributed much knowledge, not only to horticulture, but also the scientific understanding of the relationship between the vines and the butterflies. In 1990 he founded the Passiflora Society International (PSI), and until recent years was president and prime mover. Through his lifelong interest in nature photography, he started a collection of passionflower photos which has grown now into this pictorial atlas. Completed by renowned Passiflora authority, Ronald Boender, together with John MacDougal, Ph.D., and John Vanderplank, Ph.D. comprehensively highlights the breadth and beauty of the species occurring in the wild. Lavish contributions by 27 other photographers expand the photographic atlas to other climates, including cool-loving Andean species. Readers will delight in exploring page after page of amazing and intricate flowers and leaves of every color and form. This beautiful informational guide will be instructive and engaging to all readers -- gardeners, hobbyists, and scientists alike. This is a wonderful gift for any nature lover or gardener or anyone interested in tropical plants or nature photography.

The Study of Plants in a Whole New Light “Matt Candeias succeeds in evoking the wonder of plants with wit and wisdom.” ―James T. Costa, PhD, executive director, Highlands Biological Station and author of Darwin's Backyard #1 New Release in Nature & Ecology, Plants, Botany, Horticulture, Trees, Biological Sciences, and Nature Writing & Essays In his debut book, internationally-recognized blogger and podcaster Matt Candeias celebrates the nature of plants and the extraordinary world of plant organisms. A botanist’s defense. Since his early days of plant restoration, this amateur plant scientist has been enchanted with flora and the greater environmental ecology of the planet. Now, he looks at the study of plants through the lens of his ever-growing houseplant collection. Using gardening, houseplants, and examples of plants around you, In Defense of Plants changes your relationship with the world from the comfort of your windowsill. The ruthless, horny, and wonderful nature of plants. Understand how plants evolve and live on Earth with a never-before-seen look into their daily drama. Inside, Candeias explores the incredible ways plants live, fight, have sex, and conquer new territory. Whether a blossoming botanist or a professional plant scientist, In Defense of Plants is for anyone who sees plants as more than just static backdrops to more charismatic life forms. In this easily accessible introduction to the incredible world of plants, you’ll find: • Fantastic botanical histories and plant symbolism • Passionate stories of flora diversity and scientific names of plant organisms • Personal tales of plantsman discovery through the study of plants If you enjoyed books like The Botany of Desire, What a Plant Knows, or The Soul of an Octopus, then you’ll love In Defense of Plants.

"Whatever your level of interest or curiosity, Vanderplank has provided the information for further exploration. Separate chapters explain the classification and structure of passion flowers, the legend and etymology, cultivation, propagation, hybridization, pests and diseases, and the unique interactions of butterflies and passion flowers. The bulk of the book provides detailed information on 100 taxa, including specific botanical descriptions, along with a narrative covering their discovery, distribution, and the author's experience with these species or hybrids. Appending the text is a useful identification key in chart form, lists of addresses and suppliers, a glossary, and a brief bibliography. . . . John Vanderplank's Passion Flowers is the most comprehensive work on the subject in more than fifty years." -- Steven Foster, American Horticulturist (review of the first edition) "Lost flower of the Andes is blooming in Britain." This headline in the Daily Telegraph celebrated the last remaining example of Passiflora lourdesae, a herbaceous climber from a rapidly developing region of Venezuela that was raised from a cutting by John Vanderplank -- the only successful attempt from a dozen cuttings sent to botanists around the world. The story of this dramatic recovery from extinction is one of the delights of this new edition of Passion Flowers. This edition adds 53 new species, bringing the total number of species documented to over 150, and includes 41 new color photographs. The book now illustrates nearly a quarter of all known species. In addition there are 50 new line drawings -- all showcased in a new, larger format.

The diseases are among the main factors responsible for the low productivity and losses in commercial passion fruit crops. Among the agents that cause pathologies, Fusarium oxysporium S, Fusarium solani Sacc and Phytophora spp., deserve attention. The use of tolerant cultivars stands out as one of the most effective, economic and ecological measures in the control of the disease. In the case of passion fruit, this strategy is essential based on the high susceptibility of current cultivars. Fusarium spp normally compromises the efficiency of the root system, as well as the conductive vessels of the sage, reducing the longevity of the plant and limiting the use of the areas contaminated by the fungus. Tolerance to F. solani was found in Passiflora gibertti N.E. Brown, P. nítida Kunth, P. macrocarpa Mast, P. quadrangularis L., P. setacea L., P. alata Curtis and P. caerulea L., presenting grafting with the use of tolerant species a viable alternative to attenuate the problems caused by this fungi. Thus, with the use of tolerant wild species as rootstocks, it allows coexistence with premature death of plants and provides the formation of healthier and uniform crops. However, there is little information on the effect of wild Passiflora species such as passion fruit rootstock.

The Heliconius butterflies are one of the classic systems in evolutionary biology and have contributed hugely to our understanding of evolution over the last 150 years. Their dramatic radiation and remarkable mimicry has fascinated biologists since the days of Bates, Wallace, and Darwin. The Ecology and Evolution of Heliconius Butterflies is the first thorough and accessible treatment of the ecology, genetics, and behaviour of these butterflies, exploring how they offer remarkable insights into tropical biodiversity. The book starts by outlining some of the evolutionary questions that Heliconius research has helped to address, then moves on to an overview of the butterflies themselves and their ecology and behaviour before focussing on wing pattern evolution, and finally, speciation. Richly illustrated with 32 colour plates, this book makes the extensive scientific literature on Heliconius butterflies accessible to a wide audience of professional ecologists, evolutionary biologists, entomologists, and amateur collectors.
