Lone Star Field Guide to Wildflowers, Trees, and Shrubs of Texas [EPUB ebook] 

With the Rocky Mountains to the west, the Great Plains to the North, the Chihuahan Desert to the south and the Gulf of Mexico to the east, Texas lies at the biological crossroads of North America. More than 5, 000 flowering plants, from tiny herbs to towering trees, grow in these vast and diverse habitats. This book describes more than 600 species of the most common Texas wildflowers, trees, shrubs, and cacti in a well-illustrated, easy-to-use format. With over 400 color photographs, drawings, identification keys, and range maps for each species, the book uses a step-by-step process to easily identify major plant features. (Wildflowers, for example, are arranged by color for easy identification.) Essentially three books in one, this handy guide will be invaluable for weekend naturalists, gardeners, and nature lovers in general.
