Plant Variation and Classification

The earth sprouts a huge diversity of plant life--including 250,000 known species of flowering plants--and many more are waiting to be discovered and classified. Each plant species is carefully divided into categories by its characteristics such as its root system, leaf pattern, and whether it produces seeds. This book provides a detailed account of plants and the methods by which they are classified. Helpful diagrams, drawings, photographs, and sidebars will fascinate readers.
