The Itza’ Maya of the Petén in Guatemala preside over a unique rainforest biosphere in danger of disappearing. Equally at risk is their own botanical knowledge, from taxonomy to medicinal uses. This volume contains a history of the Petén Itza’ Maya; explanation of Itza’ taxonomy; tables and keys to plant usage; common names in English, Spanish, and several indigenous languages; and much more.

Plants are an indispensable part of our everyday lives. From the coffee bean that gets roasted for our morning brew to the grasses that feed the animals we eat to the rubber tree that provides the raw materials used in the tires of our cars, we depend on plants for nearly every aspect of our lives.
           
With What Have Plants Ever Done for Us?, Stephen Harris takes readers step by chronological step through the role of plants in the rise of the Western world, with sojourns through the history of trade, travel, politics, chemistry, and medicine. Plants are our most important food source. Some, such as barley, have been staples since the earliest times. Others, like the oil palm, are relative newcomers to the Western world. Over time, the ways we use some plants has also dramatically changed: Beets, a familiar sight on the dinner plate, were once thought to be an effective treatment for leprosy and now show significant promise as a sustainable biofuel. What, one wonders, might the future thus hold for the mandrake or woad? Plants have also held potent cures to some of our most prevalent diseases. An extract from the bark of the yew tree, for instance, is commonly used in the treatment of cancer.
           
Wide-ranging and thoroughly engaging, What Have Plants Ever Done for Us? will help readers cultivate a deeper appreciation for our branched and rooted friends who ask little in return for their vast contributions save for a little care and water.

Aimed at practitioners in governmental institutions and NGOs working in Africa and Latin America, this book has been written to promote the conservation and sustainable use of wild multipurpose plant species in conservation, agriculture, and forestry projects, addressing the UN Sustainable Development Goals “to end poverty, protect the planet and ensure prosperity for all.”
The publication forms one of the main dissemination achievements of The MGU–Useful Plants Project, developed under Kew’s Millennium Seed Bank partnership, to conserve and use sustainably wild plants important for rural communities in Botswana, Kenya, Mali, South Africa, and Mexico. Institutional partners led the project in each country, involving rural communities, local authorities, and schools. A scientific approach was applied throughout.
The core of this book presents detailed species profiles of 110 plants selected for their importance to communities and livelihoods. The profiles are structured in a clear and consistent format, providing information on taxonomy and nomenclature, plant descriptions, fruit and seed structures, distribution, habitat, uses, known hazards and safety, conservation status, seed conservation, propagation, and trading, along with key references from the literature.
 

Originally published in 1999, Wildflowers and Other Plants of Iowa Wetlands was the first book to focus on the beauty and diversity of the wetland plants that once covered 1.5 million acres of Iowa. Now this classic of midwestern natural history is back in print with a new format and all-new photographs, just as Iowa’s wetlands are getting the respect and attention they deserve.

In clear and accessible prose, authors Sylvan Runkel and Dean Roosa provide common, scientific, and family names; the Latin or Greek meaning of the scientific names; habitat and blooming times; and a complete description. Plants are presented by habitat (terrestrial or aquatic), then refined by habit (e.g., emergent, floating, or submerged) or taxonomic group (e.g., ferns and allies or trees, shrubs, and vines). Particularly interesting is the information on the many ways in which Native Americans and early pioneers used these plants for everything from pain relief to tonics to soup and the ways that wildlife today use them for food and shelter. Each of the more than 150 species accounts is accompanied by a brilliant full-page color photograph by botanist Thomas Rosburg, who has also updated the nomenclature and descriptions for certain species.

After decades of being considered an enemy of the settler, the farmer, and the citizen, Iowa’s wetlands have come into their own. We are finally caring for these important habitats. Runkel and Roosa’s updated field companion will be a valuable guide to today’s preservation and restoration initiatives.

This classic of midwestern natural history is back in print with a new format and new photographs. Originally published in 1979, Wildflowers of Iowa Woodlands introduced many naturalists to the beauty and diversity of the native plants of the wooded communities that once covered more than 6 million acres of the state. Now redesigned with updated names and all-new images, this reliable field companion will introduce woodland wildflowers to a new generation of outdoor enthusiasts in the Upper Midwest.

The species accounts are accompanied by brilliant full-page color photographs by Larry Stone, Thomas Rosburg, and Carl Kurtz. In clear, straightforward, and accessible prose, authors Sylvan Runkel and Alvin Bull provide common, scientific, and family names; the Latin or Greek meaning of the scientific names; habitat and blooming times; and a complete description of plant, flower, and fruit. Particularly interesting is the information on the many ways in which Native Americans and early pioneers used these plants for everything from pain relief to insecticides to tonics.

Iowa’s original savannas, woodlands, and forests were cleared with amazing thoroughness, yet enough beauty and diversity remain to give joy to hikers, birders, and mushroomers. Wildflowers of Iowa Woodlands will inspire both amateurs and professionals with the desire to learn more about the wonders of today’s woodlands.
