Book Description
The legacy of Alexander von Humboldt (1769–1859) looms large over the natural sciences. His 1799–1804 research expedition to Central and South America with botanist Aimé Bonpland set the course for the great scientific surveys of the nineteenth century, and inspired such essayists and artists as Emerson, Goethe, Thoreau, Poe, and Church. The chronicles of the expedition were published in Paris after Humboldt’s return, and first among them was the 1807 “Essay on the Geography of Plants.” Among the most cited writings in natural history, after the works of Darwin and Wallace, this work appears here for the first time in a complete English-language translation. Covering far more than its title implies, it represents the first articulation of an integrative “science of the earth, ” encompassing most of today’s environmental sciences. Ecologist Stephen T. Jackson introduces the treatise and explains its enduring significance two centuries after its publication.

Book Description
This meticulously researched compendium provides every aspect of growing, identifying, harvesting, preserving, and using more than 500 species of herbs. Thorough profiles provide a plant's botanical name and family, whether it is an annual or perennial, its height, hardiness, light requirements, water consumption, required soil type, and pH. The often fascinating history of the plant, the chemistry of its essential oils, and its culinary, landscape, and craft uses are also included, as is advice on how to propagate. For the first edition of their work, both authors received The Gertrude B. Foster Award for Excellence in Herbal Literature from the Herb Society of America. This new edition adds important species and includes updated nomenclature.

Book Description
Fourteen informative papers dealing with their DNA, species interactions, adventiveness, host specificity, potential as boi-contol agents of weeds, chemical control, behaviour, their role in fungal pathogen epidemiology, influence in forests and on ornamentals, collecting and mounting techniques and their interaction with crops are presented here. This is an extensive and valuable contribution to eriophyoid science and a must for present and future researchers in this field.
