Book Description
This study was originally planned to follow certain regional papers with a similar account of the family Scrophulariaceae (figwort or foxglove family) for the Middle Atlantic & N. Central States. But it soon seemed preferable to include the southern Appalachians & the whole Atlantic Coastal Plain. The flora of the northern states has been profoundly modified by the glacial epoch, & any understanding of the composition & distribution of our northern flora should also consider the adjoining southern territory where vegetation was little or not affected & from which the north was again populated. So, it was decided to include again the South Atlantic & the West Gulf States. The plan of this study is both more thorough & more comprehensive than earlier efforts. Illus.

Book Description
This study is based upon the collections made over more than 30 years prior to 1943 by Ralph Steward at Rawalpindi in northwestern India. It was in 1911, as a young instructor there, that Steward commenced the gathering of specimens, & in 1912 that he made his first trip into Kashmir. Since then he had been repeatedly into the Himalayas, spending vacations in Kashmir & collecting in adjacent territory north to Baltistan & east to Ladakh; he traversed the mountains of Lahul & Kulu, & also summered at Landour above Dehra Dun. Author Pennell made Stewart¿s acquaintance in 1914 & 1915. Pennell asked that on his return to India he would pay particular attention to the Scrophulariaceae, a request that Stewart amply answered. 25 plates.

Book Description
The European Garden Flora is the definitive manual for the accurate identification of cultivated ornamental flowering plants. Designed to meet the highest scientific standards, the vocabulary has nevertheless been kept as uncomplicated as possible so that the work is fully accessible to the informed gardener as well as to the professional botanist. This new edition has been thoroughly reorganised and revised, bringing it into line with modern taxonomic knowledge. Although European in name, the Flora covers plants cultivated in most areas of the United States and Canada as well as in non-tropical parts of Asia and Australasia. Volume 5 completes the series, and includes many important ornamental families, such as Labiatae, Solanaceae, Scrophulariaceae, Acanthaceae, Campanulaceae, and the largest family of Dicotyledons, the Compositae.

Book Description
This volume presents a detailed description of more than thirty-five wildflower species of the Northeast, describing their colors, habitats, range, pollination, history, cultural lore, medicinal uses, and literary and artistic references. The spring-blooming wildflowers looked at range from old favorites to lesser-known species. Featuring more than 500 full-color photos in large-sized format, the book delves deep into the life histories, lore, and cultural uses of more than 35 plant species. The narrative covers topics such as the naming of wildflowers; the reasons for taxonomic changes; pollination of flowers and dispersal of seeds; uses by Native Americans; related species in other parts of the world; herbivores, plant pathogens, and pests; medicinal uses; and wildflower references in history, literature, and art. The photos capture the beauty of these plants and also illustrate the concepts discussed in the text.
