How herbaria illuminate the past and future of plant science Collections of preserved plant specimens, known as herbaria, have existed for nearly five centuries. These pressed and labeled plants have been essential resources for scientists, allowing them to describe and differentiate species and to document and research plant changes and biodiversity over time--including changes related to climate. Maura C. Flannery tells the history of herbaria, from the earliest collections belonging to such advocates of the technique as sixteenth-century botanist Luca Ghini, to the collections of poets, politicians, and painters, and to the digitization of these precious specimens today. She charts the growth of herbaria during the Age of Exploration, the development of classification systems to organize the collections, and herbaria's indispensable role in the tracking of climate change and molecular evolution. Herbaria also have historical, aesthetic, cultural, and ethnobotanical value--these preserved plants can be linked to the Indigenous peoples who used them, the collectors who sought them out, and the scientists who studied them. This book testifies to the central role of herbaria in the history of plant study and to their continued value, not only to biologists but to entirely new users as well: gardeners, artists, students, and citizen-scientists.
Botany is a subfield of biology that focuses on the study of plant life and growth from a scientific standpoint. It is an expansive scientific field that studies a wide range of topics related to plants i.e.algae, fungi, Pteridophytes, Gymnosperm etc. These topics include growth, reproduction, metabolism, development, illnesses, chemical qualities, and the evolutionary links between the many groups of organisms. Botany is one of the oldest disciplines, and its origins may be traced back to early human efforts to identify which plants were safe to eat, which were useful for medicine, and which were harmful to humans. The study of botany has expanded to include more than 550000 species at this point in time. This significance may be seen via a variety of lenses, such as the influence that it has on farming, medicine, and efforts to preserve the natural world. The use of botany in agricultural settings is among its most significant uses. Research in botany has resulted in the creation of new and better crop types that are more resistant to invasive organisms, infectious illnesses, and the effects of environmental stress. This has significantly contributed to an increase in global food security as well as a reduction in poverty in a number of developing nations.
The wilderness is much closer than you think. Passed through, negotiated, unnamed, unacknowledged: the edgelands - those familiar yet ignored spaces which are neither city nor countryside - have become the great wild places on our doorsteps. In the same way the Romantic writers taught us to look at hills, lakes and rivers, poets Paul Farley and Michael Symmons Roberts write about mobile masts and gravel pits, business parks and landfill sites, taking the reader on a journey to marvel at these richly mysterious, forgotten regions in our midst. Edgelands forms a critique of what we value as 'wild', and allows our allotments, railways, motorways, wasteland and water a presence in the world, and a strange beauty all of their own.

A masterpiece, full of charm and humor." --Dr. Rebecca W. Dolan, Director, Friesner Herbarium, Butler University Whether it's urban, suburban, or rural, nearly every property has some shade, if only on the north side of the house. Countless more are "blessed" with giant trees planted decades ago that screen out the sunlight. Under such conditions, you may think that it's impossible to have an interesting garden without a lot of work. Not so if you are willing to learn about the plethora of easygoing horticultural gems that don't require full sun. Most gardeners think only of impatiens and hostas for their shady areas, but shade gardening can be far more interesting, and even exciting--and you need not work too hard at it if you incorporate some lesser-known but easy-to-grow plants into your landscape. Judiciously mixing the common plants with the more unusual ones can help the busy, tired, or lazy gardener create a special and unique retreat. Carolyn Harstad, author of the best-selling Go Native!, organizes this book around the principle that an interesting shade garden is well balanced and has a variety of plantings. Early chapters focus on designing the low-maintenance garden. Further chapters discuss small trees, shrubs, dwarf conifers, vines, ground covers, ferns, grasses, perennials, woodland wildflowers, spring bulbs, and annuals (yes, there are annuals that enjoy shade!). She discusses hundreds of shade-tolerant plants hardy in Zones 4-8, suggests how they may be used and combined, and recommends methods to reduce garden maintenance--a universal concern in this fast-paced world. With its informative text, accurate drawings, and colorful photographs, this book is a "must have" for gardeners across much of North America.
Grasses are among the most ubiquitous plants on the planet. They inhabit a wide geographic range and are found in a variety of natural habitats. The small parts of the grass flower and specialized terminology, however, can make identifying grasses a challenging endeavor. Sarah Chamberlain’s Field Guide to Grasses of the Mid-Atlantic makes identification simpler for everyone—regardless of their previous botanical knowledge. Featuring an easy-to-use dichotomous key, this is a user-friendly guide to more than 300 types of grasses found from the Blue Ridge Mountains and southern plains to the Appalachians and the Allegheny Plateau. Each major entry contains detailed species diagrams as well as common names, habitats, and distribution. The book’s opening sections outline the parts of grass flowers and describe stem, leaf, and sheath characteristics. With a wealth of illustrations, instructions on how to use the key, and a glossary of terms, Field Guide to Grasses of the Mid-Atlantic is an indispensable reference for naturalists and conservationists, botanists, land management professionals, and students and scholars of mid-Atlantic flora.
