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.

Second Growth
The Promise of Tropical Forest Regeneration in an Age of Deforestation
Robin L. Chazdon
University of Chicago Press, 2014
For decades, conservation and research initiatives in tropical forests have focused almost exclusively on old-growth forests because scientists believed that these “pristine” ecosystems housed superior levels of biodiversity. With Second Growth, Robin L. Chazdon reveals those assumptions to be largely false, bringing to the fore the previously overlooked counterpart to old-growth forest: second growth.

Even as human activities result in extensive fragmentation and deforestation, tropical forests demonstrate a great capacity for natural and human-aided regeneration. Although these damaged landscapes can take centuries to regain the characteristics of old growth, Chazdon shows here that regenerating—or second-growth—forests are vital, dynamic reservoirs of biodiversity and environmental services. What is more, they always have been.

With chapters on the roles these forests play in carbon and nutrient cycling, sustaining biodiversity, providing timber and non-timber products, and integrated agriculture, Second Growth not only offers a thorough and wide-ranging overview of successional and restoration pathways, but also underscores the need to conserve, and further study, regenerating tropical forests in an attempt to inspire a new age of local and global stewardship.

Sedges
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.

Sedges
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.

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.

The Social Lives of Forests
Past, Present, and Future of Woodland Resurgence
Edited by Susanna B. Hecht, Kathleen D. Morrison, and Christine Padoch
University of Chicago Press, 2014
Forests are in decline, and the threats these outposts of nature face—including deforestation, degradation, and fragmentation—are the result of human culture. Or are they? This volume calls these assumptions into question, revealing forests’ past, present, and future conditions to be the joint products of a host of natural and cultural forces. Moreover, in many cases the coalescence of these forces—from local ecologies to competing knowledge systems—has masked a significant contemporary trend of woodland resurgence, even in the forests of the tropics.

Focusing on the history and current use of woodlands from India to the Amazon, The Social Lives of Forests attempts to build a coherent view of forests sited at the nexus of nature, culture, and development. With chapters covering the effects of human activities on succession patterns in now-protected Costa Rican forests; the intersection of gender and knowledge in African shea nut tree markets; and even the unexpectedly rich urban woodlands of Chicago, this book explores forests as places of significant human action, with complex institutions, ecologies, and economies that have transformed these landscapes in the past and continue to shape them today. From rain forests to timber farms, the face of forests—how we define, understand, and maintain them—is changing.
