“What is a weed,” opined Emerson, “but a plant whose virtues have not yet been discovered?” While that may be a worthy notion in theory, these plants of undiscovered virtue cause endless hours of toil for backyard gardeners. Wherever they take root, weeds compete for resources, and most often win. They also wreak havoc on industry—from agriculture to golf courses to civic landscape projects, vast amounts of money are spent to eradicate these virile and versatile invaders. With so much at stake, reliable information on weeds and their characteristics is crucial. Richard Dickinson and France Royer shed light on this complex world with Weeds of North America, the essential reference for all who wish to understand the science of the all-powerful weed.

Encyclopedic in scope, the book is the first to cover North American weeds at every stage of growth. The book is organized by plant family, and more than five hundred species are featured. Each receives a two-page spread with images and text identification keys. Species are arranged within family alphabetically by scientific name, and entries include vital information on seed viability and germination requirements.

Whether you believe, like Donald Culross Peattie, that “a weed is a plant out of place,” or align with Elizabeth Wheeler Wilcox’s “weeds are but unloved flowers,” Dickinson and Royer provide much-needed background on these intrusive organisms. In the battle with weeds, knowledge truly is power. Weeds of North America is the perfect tool for gardeners, as well as anyone working in the business of weed ecology and control.

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.
 

Describing more than 1,100 species, this is a comprehensive guide to wildflowers in Wisconsin and parts of Minnesota, Michigan, Illinois, Indiana, Iowa, and Ontario. A new introduction to this second edition discusses wildflowers in the context of their natural communities. Packed with detailed information, this field guide is compact enough to be handy for outdoors lovers of all kinds, from novice naturalists to professional botanists. It includes:

• more than 1,100 species from 459 genera in 100 families
• many rare and previously overlooked species
• 2,100 color photographs and 300 drawings
• Wisconsin distribution maps for almost all plants
• brief descriptions including distinguishing characteristics of the species
• Wisconsin status levels for each species of wildflower (native, invasive, endangered, etc.)
• derivation of Latin names.

Many recreational hikers have stopped along the trail to admire a wildflower only to wonder what, exactly, they are looking at. Wildflowers of the Mountain West is a useful field guide that makes flower identification easy for the general outdoor enthusiast.

Many available plant guides are too technical or cumbersome for non-specialists to embrace. Covering New Mexico, Colorado, Wyoming, Idaho, Utah, Nevada and Oregon, this book is perfect for the enthusiasts who has little botanical knowledge but would like to know more about the wildflowers they are seeing. Organized by flower color for easy reference, plant records include the common and scientific names, a description of typical characteristics, habitat information and distribution maps, look-alike species, color photographs, and informative commentary. In addition, the book provides a useful introduction to the Mountain West region, along with line drawings to illustrate basic flower parts, shapes, and arrangements; a glossary of common botanical terms; a quick search key; and an index.

The book is spiral-bound, making it easy to bring along while hiking, backpacking, or biking, and stunning full color photographs make visual confirmation of flower type simple and straightforward.
 

Edwardian botanist Ernest Wilson was the foremost plant collector of his generation, singlehandedly responsible for introducing more than one thousand plant species to Western gardens, many of them collected during his extensive travels in China.

In this book, Peter Bernhardt takes us on a grand tour of the botanical realm, weaving engaging descriptions of the lovely shapes and intriguing habits of flowering plants with considerations of broader questions, such as why there are only six basic shapes of flowers and why the orchid family is so numerous and so bizarre. Everyone from amateur naturalists and gardeners to plant scientists will find Wily Violets and Underground Orchids a lively guide to botanical lore.

Compared to the obvious complexity of animals, plants at a glance seem relatively simple in form. But that simplicity is deceptive: the plants around us are the result of millennia of incredible evolutionary adaptations that have allowed them to survive, and thrive, under wildly changing conditions and in remarkably specific ecological niches. Much of this innovation, however, is invisible to the naked eye.
            With Wonders of the Plant Kingdom, the naked eye gets an unforgettable boost. A stunning collaboration between science and art, this gorgeous book presents hundreds of images of plants taken with a scanning electron microscope and hand-colored by artist Rob Kesseler to reveal the awe-inspiring adaptations all around us. The surface of a peach—with its hairs, or trichomes, and sunken stomata, or breathing pores—emerges from these pages in microscopic detail. The dust-like seeds of the smallest cactus species in the world, the Blossfeldia liliputana—which measures just twelve millimeters fully grown—explode here with form, color, and character, while the flower bud of a kaffir lime, cross-sectioned, reveals the complex of a flower bud with the all-important pistil in the center.
            Accompanying these extraordinary images are up-to-date explanations of the myriad ways that these plants have ensured their own survival—and, by proxy, our own. Gardeners and science buffs alike will marvel at this wholly new perspective on the world of plant diversity.

A comprehensive guide that includes a vast range of species and plant communities and employs thorough, original keys. Based primarily on vegetative characteristics, the keys don't require that flowers or other reproductive features be present, like many plant guides. And this guide's attention to woody plants as a whole allows one to identify a much greater variety of plants. That especially suits an arid region such as Utah with less diverse native trees. Woody plants are those that have stems that persist above ground even through seasons that don't favor growth, due to low precipitation or temperatures.

Woody Plants of Utah employs dichotomous identification keys that are comparable to a game of twenty questions. They work through a process of elimination by choosing sequential alternatives.

Detailed, illustrated plant descriptions complement the keys and provide additional botanical and environmental information in relation to a useful introductory categorization of Utah plant communities. Supplementary tools include photos, distribution maps, and an illustrated glossary.

Woody Plants of Western African Forests is an illustrated guide to the identification of 2200 trees, lianes and shrubs found in the forests of West Africa, from Senegal to Ghana. This is all the woody plants and more than 80% of the higher plants in the forests of this region, known to biogeographers as Upper Guinea. This represents 5% of all flowering plant genera in the world—1% of the species — so the book is relevant to anyone interested in tropical plants, especially but not only in the forests of tropical Africa.

Laid out as keys and with short descriptions of each species, it contains over 5,600 photographs, line drawings and maps. And, while many guides only offer hints to naming plants when they are not in flower, here the authors have based identification on leaves, bark, shoots, scent ,taste and other characters easily observed at most times.

Funded by the European Union, through its ECOSYN project (based at Wageningen University), which supports forest biodiversity and management in Upper Guinea, this magnificent, beautiful book is an indispensable reference for everyone committed to the conservation and sustainable development of Africa’s forest.

The palm family, considered to be second only to the grasses among monocotyledonous plants of economic importance, is of immense significance to man, especially among rural communities in the tropics, where wild palms are intensively utilised. The 'World Checklist of Palms' is the unique resource that lists all validly published names of palms, providing the source of their publication and indication of which names are currently accepted and which are synonyms. Geographical distribution is also included for all accepted species.
