Sacred Leaves of Candomblé
African Magic, Medicine, and Religion in Brazil
By Robert A. Voeks
University of Texas Press, 1997

Winner, Hubert Herring Book Award, Pacific Coast Council on Latin American Studies

Candomblé, an African religious and healing tradition that spread to Brazil during the slave trade, relies heavily on the use of plants in its spiritual and medicinal practices. When its African adherents were forcibly transplanted to the New World, they faced the challenge not only of maintaining their culture and beliefs in the face of European domination but also of finding plants with similar properties to the ones they had used in Africa.

This book traces the origin, diffusion, medicinal use, and meaning of Candomblé's healing pharmacopoeia—the sacred leaves. Robert Voeks examines such topics as the biogeography of Africa and Brazil, the transference—and transformation—of Candomblé as its adherents encountered both native South American belief systems and European Christianity, and the African system of medicinal plant classification that allowed Candomblé to survive and even thrive in the New World. This research casts new light on topics ranging from the creation of African American cultures to tropical rain forest healing floras.

The Saguaro Cactus
A Natural History
David Yetman, Alberto Búrquez, Kevin Hultine, and Michael Sanderson, with Frank S. Crosswhite
University of Arizona Press, 2020
The saguaro, with its great size and characteristic shape—its arms stretching heavenward, its silhouette often resembling a human—has become the emblem of the Sonoran Desert of southwestern Arizona and northwestern Mexico. The largest and tallest cactus in the United States, it is both familiar and an object of fascination and curiosity.

This book offers a complete natural history of this enduring and iconic desert plant. Gathering everything from the saguaro’s role in Sonoran Desert ecology to its adaptations to the desert climate and its sacred place in Indigenous culture, this book shares precolonial through current scientific findings.

The saguaro is charismatic and readily accessible but also decidedly different from other desert flora. The essays in this book bear witness to our ongoing fascination with the great cactus and the plant’s unusual characteristics, covering the saguaro’s: history of discovery, place in the cactus family, ecology, anatomy and physiology, genetics, and ethnobotany. The Saguaro Cactus offers testimony to the cactus’s prominence as a symbol, the perceptions it inspires, its role in human society, and its importance in desert ecology.

Saving Orchids
Stories of Species Survival in a Changing World
Philip Seaton and Lawrence W. Zettler
University of Chicago Press, 2025

A gorgeously illustrated ode to the beauty and significance of orchids—and to those fighting to save these unique plants across the globe.

Until recently, a myriad of lifeforms enriched our lives. In parts of the United States, listening to a nighttime chorus of frogs in the neighborhood marsh was an archetypal touchstone of childhood. Children would search for tadpoles, just steps away from native Lady’s Tresses orchids. Year by year, the chorus became quieter. Today, only a few frogs and orchids remain. Is this the world we want our children to inherit? Do we want orchids to slip through our fingers and, eventually, to vanish?

Philip Seaton and Lawrence W. Zettler have traveled the world over the past three decades, studying orchids—the flagship group for plant conservation. This book is a culmination of stories about the people—young and old alike—dedicated to protecting these remarkable plants from extinction. In the 19th century, vast numbers of orchids were removed from the wild, shipped, and sold by collectors. Today, remnants of these original habitats remain that scientists are striving to protect undeterred by impending climate change. Readers will be taken on a journey into the life history of an orchid (e.g., bizarre pollination mechanisms, risky liaison with fungi) through the lens of science, and how this information is applied to modern conservation efforts.

Scorched Earth
How the Fires of Yellowstone Changed America
Rocky Barker
Island Press, 2005

In 1988, forest fires raged in Yellowstone National Park, destroying more than a million acres. As the nation watched the land around Old Faithful burn, a longstanding conflict over fire management reached a fever pitch. Should the U.S. Park and Forest Services suppress fires immediately or allow some to run their natural course? When should firefighters be sent to battle the flames and at what cost?

In Scorched Earth, Barker, an environmental reporter who was on the ground and in the smoke during the 1988 fires, shows us that many of today's arguments over fire and the nature of public land began to take shape soon after the Civil War. As Barker explains, how the government responded to early fires in Yellowstone and to private investors in the region led ultimately to the protection of 600 million acres of public lands in the United States. Barker uses his considerable narrative talents to bring to life a fascinating, but often neglected, piece of American history. Scorched Earth lays a new foundation for examining current fire and environmental policies in America and the world.

Our story begins when the West was yet to be won, with a colorful cast of characters: a civil war general and his soldiers, America's first investment banker, railroad men, naturalists, and fire-fighters-all of whom left their mark on Yellowstone. As the truth behind the creation of America's first national park is revealed, we discover the remarkable role the U.S. Army played in protecting Yellowstone and shaping public lands in the West. And we see the developing efforts of conservation's great figures as they struggled to preserve our heritage. With vivid descriptions of the famous fires that have raged in Yellowstone, the heroes who have tried to protect it, and the strategies that evolved as a result, Barker draws us into the very heart of a debate over our attempts to control nature and people.

This entertaining and timely book challenges the traditional views both of those who arrogantly seek full control of nature and those who naively believe we can leave it unaltered. And it demonstrates how much of our broader environmental history was shaped in the lands of Yellowstone.

Seasonally Dry Tropical Forests
Ecology and Conservation
Edited by Rodolfo Dirzo, Hillary S. Young, Harold A. Mooney, and Gerardo Ceballos
Island Press, 2010
Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject.
 
Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests.
 
The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use.
 
Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

Carex
Robert H. Mohlenbrock
Southern Illinois University Press, 2011
Sedges: Carex is the fourteenth vol­ume of the Illustrated Flora of Illinois series and the sixth and last volume devoted to monocots—plants that have a single seed leaf, or coty­ledon, upon germination.
 
Since the volume’s original publica­tion in 1999, thirty-four additional species of plants have been recog­nized in Illinois. Some are discover­ies from recent field work, some are from more thorough searches of herbaria, and others are from differ­ent taxonomic philosophies.
 
For each species of Carex in Illinois, there is a full illustration showing the habit of the plant and close-ups of various vegetative and reproduc­tive structures that are crucial for the identification of the individual species. There is also a complete description of each species as well as a detailed discussion of the no­menclature and habitats. Range maps show the county distribution of each species in Illinois. A new and detailed key is provided for identification of the species.

Carex
Robert H. Mohlenbrock. Illustrated by Paul Nelson
Southern Illinois University Press, 1999
Sedges: Carex is the fourteenth volume of the Illustrated Flora of Illinois series and the sixth and last volume devoted to monocots, or plants that have a single seed-leaf, or cotyledon, upon germination. For each of the 159 species of Carex in Illinois, there is a full illustration showing the habit of the plant and close-ups of various vegetative and reproductive structures that are crucial for the identification of the individual species. There is also a complete description of each species as well as a discussion of the nomenclature and habitats. Range maps show the county distribution of each species in Illinois. A detailed key is provided for identification of the species.



Unique in several respects, Carex is by far the most numerous genus of plants in Illinois. Because of the vast number of species, the similarity of many of the species, and the relatively small size of the critical reproductive structures, the members of this genus are extremely confusing to identify. This book, with its detailed descriptions, key, and precise illustrations, should aid the interested person in the identification of these plants.



Since more than three-fourths of the species of Carex in Illinois are inhabitants of wetlands, an understanding of the genus is critical for those working in wetlands. Amateur and professional botanists will find the information extremely valuable, as well as environmental and conservation groups, garden clubs, farm bureaus, home extension groups, scout organizations, and school libraries. Persons working in natural areas programs and in rare and endangered species programs and those working on environmental impact assessments and wildlife management projects will also find the information pertinent.

Cyperus to Scleria
Robert H. Mohlenbrock
Southern Illinois University Press, 2001

This second edition of Sedges: Cyperus to Scleria brings up to date the identification of species of sedges in Illinois (except Carex) since publication of the first edition in 1976.

During the intervening years, several additions to the sedge flora of Illinois have been made, and many new distributional records have been added. Also, a large number of nomenclatural changes have taken place, resulting in several alterations of scientific names. New illustrations have been provided for all of the additions. 

In his introductory material, Robert H. Mohlenbrock discusses the morphology of sedges and the habitats where they can be found. Although the semitechnical keys and descriptions are familiar to experienced botanists, he has simplified them as much as possible to accommodate the novice in sedge identification. He has also included a new key to the sedges and to each genus in which additional species have been added.

For each species, Mohlenbrock has provided a description, statement of habitat and range, Illinois distribution map, discussion, synonymy, and line illustrations showing its diagnostic features. Sedges: Cyperus to Scleria contains 128 illustrations.

Seeds
A Natural History
Carolyn Fry
University of Chicago Press, 2016
From the magnificence of a towering redwood to the simple elegance of a tiny dandelion, seed-bearing plants abound on planet Earth. The sheer diversity of plants thriving today is largely thanks to the evolution of the seed, as this made plants resilient to environmental changes by enabling them to await optimum conditions for growth before springing to life. In a time of declining biodiversity, studying seeds is now helping scientists preserve this plant diversity for future generations.

With Seeds, Carolyn Fry offers a celebration of these vital but unassuming packages of life. She begins with a sweeping tour through human history, designed to help us understand why we should appreciate and respect these floral parcels. Wheat, corn, and rice, she reminds us, supply the foundations of meals eaten by people around the world. Countless medicines, oils, clothing materials, and building supplies are available only because of the versatility and variety of seed-bearing plants. Fry then provides a comprehensive history of the evolution of seeds, explaining the myriad ways that they have adapted, survived, and thrived across the globe. Delving deeper into the science of seeds, she reveals the fascinating processes of dormancy, reproduction, germination, and dispersal, and showcases the estimable work conservationists are doing today to gather and bank seeds in order to prevent species from going extinct.

Enriched by a stunning array of full-color images, Seeds offers a comprehensive exploration of some of the most enduring and essential players in the natural world.

Sex on the Kitchen Table
The Romance of Plants and Your Food
Norman C. Ellstrand
University of Chicago Press, 2018
At the tips of our forks and on our dinner plates, a buffet of botanical dalliance awaits us. Sex and food are intimately intertwined, and this relationship is nowhere more evident than among the plants that sustain us. From lascivious legumes to horny hot peppers, most of humanity’s calories and other nutrition come from seeds and fruits—the products of sex—or from flowers, the organs that make plant sex possible. Sex has also played an arm’s-length role in delivering plant food to our stomachs, as human handmade evolution (plant breeding, or artificial selection) has turned wild species into domesticated staples.

In Sex on the Kitchen Table, Norman C. Ellstrand takes us on a vegetable-laced tour of this entire sexual adventure. Starting with the love apple (otherwise known as the tomato) as a platform for understanding the kaleidoscopic ways that plants can engage in sex, successive chapters explore the sex lives of a range of food crops, including bananas, avocados, and beets, finally ending with genetically engineered squash—a controversial, virus-resistant vegetable created by a process that involves the most ancient form of sex. Peppered throughout are original illustrations and delicious recipes, from sweet and savory tomato pudding to banana puffed pancakes, avocado toast (of course), and both transgenic and non-GMO tacos.

An eye-opening medley of serious science, culinary delights, and humor, Sex on the Kitchen Table offers new insight into fornicating flowers, salacious squash, and what we owe to them. So as we sit down to dine and ready for that first bite, let us say a special grace for our vegetal vittles: let’s thank sex for getting them to our kitchen table.

Shrubs and Vines of Iowa
Peter J. van der Linden, Donald R. Farrar
University of Iowa Press, 2016
Shrubs and vines, often literally overshadowed by trees, also receive much less attention than their taller neighbors, and yet they are very important elements of the region’s natural landscape. A guide to these interesting and useful plants, this book identifies all 150 shrubs and vines native to Iowa, along with frequently seen naturalized ones. Here you’ll find the widely distributed buttonbush, the distinctive pagoda dogwoods, sumacs with their striking fall foliage, the adaptable ninebark, the attractive grape honeysuckle, the many species of Rubus and wild grapes that provide food for birds and animals, willows with their graceful promise of spring, and the diverse viburnums.

Like trees, shrubs and vines are woody plants that are easy to observe year round. The first part of this book will help you identify them. Illustrated keys take you through the identification process one step at time; these are followed by images and descriptions of all but the rarest species. Noted naturalists Peter van der Linden and Donald Farrar also provide information about each species’ distribution, ecology, and uses. Summer and winter features are covered separately to facilitate identification at these two very different times of year.

Chapters about the culture and natural history of shrubs and vines explain why the plants grow where they do in nature and show how to use them effectively in outdoor spaces. Plants native to Iowa have much to offer to the landscaper: winter hardiness, resistance to drought and climatic extremes, and food and shelter for native wildlife and pollinators. Many natives are ornamental as well, providing attractive flowers, bright autumn displays, and colorful stems or fruits in winter. The authors offer tips for selecting, planting, and caring for these plants effectively. With native plants, you can create a landscape that is sustainable, authentic to place, and satisfying to you.

Iowa and midwestern arborists, conservationists, horticulturists, landscape architects, gardeners, and all those who appreciate the beauty and value of native plants will find Shrubs and Vines of Iowa immensely useful.

Snowdrop
Gail Harland
Reaktion Books, 2016
Now in paperback, a beautifully illustrated guide to the white and green sign of spring.

Elegant flowers dressed in simple white and green, snowdrops look far too fragile to deal with wintry weather. But that’s just what they do, and they have become treasured by horticulturalists for their ability to flower in the earliest parts of the year. In this book, Gail Harland explores the role snowdrops have played in gardens and popular culture alike, as a treasured genus for enthusiast growers and an important symbol of hope and consolation.
           
Harland explores a variety of cultural meanings for the deceptively petit flower. In Victorian England snowdrop bands encouraged chastity among young women. They have been favorite subjects in paintings in many different eras, and today they are the iconic symbols of several hope-giving charities. Poets and writers have written extensively about them, as have pharmacists, who have used their chemical, galantamine, in the treatment of Alzheimer’s disease. Today some of their rarer bulbs can fetch record-breaking sums, and annual festivals that celebrate them draw people from all over the world. Walking among their brilliant white beds, Harland offers an ideal companion for any plant-lover who has ever eagerly awaited this treasured sign of spring.

Sunflowers
Stephen A. Harris
Reaktion Books, 2018
From iconic paintings by Vincent van Gogh to their much-spat seeds at baseball games, the massive, golden blossoms of sunflowers have become a part of our literary and visual cultures and daily lives, inspiring artists and poets and used by advertisers to promote countless products. But sunflowers are only the most recognizable members of the world’s largest family of plants, Asteraceae, which includes lettuce, chrysanthemums, asters, dahlias, and weeds. And in this book, Stephen A. Harris unearths the extraordinary history of this entire sunflower bouquet.

Unraveling the interplay between human cultures and the biology of these spectacular blooms over the last six thousand years, Sunflowers explores our persistent fascination with this family and how our uses of the plants have changed over millennia. Found in almost all habitats, from the driest deserts and tallest mountains to grasslands and urban wastelands, the sunflower family includes more than 32,000 species. It produces hugely popular and economically valuable ornamental flowers, as well as familiar flavorings such as tarragon and artemesia, and its members are also used in the production of antimalarial drugs, artificial sweeteners, insecticide, and fish poisons. Illustrated with many rarely seen images of the sunflower family, this beautiful volume sheds surprising new light on these familiar, sunniest of flowers.
