Published in Association with the New York Botanical GardenThe Manual of Leaf Architecture is an essential reference for describing, comparing, and classifying the leaves of flowering plants. This manual, illustrated with dozens of line drawings and more than 300 photographs of prepared stained leaves, provides a framework with comparative examples allowing consistent and detailed description of both modern and fossil leaves. This one-of-a-kind resource will be invaluable to a broad range of people who work with plants, from paleobotanists to systematists to tropical ecologists.The Manual allows for the description and identification of plants independently of their flowers, offering especially useful assistance in the case of fossil leaves (usually found in isolation) and tropical plants, whose flowering cycles can be brief and irregular, and whose fruits and flowers may be difficult to access. It provides long-needed guidelines for characterizing the organization, shape, venation, and margins of the leaves of flowering plants.Beginning with a set of illustrated definitions of leaf characters, this manual proceeds to define and illustrate the variations on each of these characters. The system presented here is based on a widely tested scheme but has been significantly expanded and refined through the detailed examination of thousands of living and fossil leaves.

This is an essential reference for describing, measuring and classifying the foliage of flowering plants. The presented system provides long-needed guidelines for characterizing the organization, shape, venation, and surface features of angiosperm leaves. In contrast to systems focusing on reproductive characters for identification, the emphasis is on macroscopic features of the leaf blade including leaf characters, venation, and tooth characters. The advantage of this system is that it allows for the classification of plants independently of their flowers, which is especially useful for fossil leaves (usually found in isolation) and tropical plants (whose flowering cycles are brief and irregular, and whose fruits and flowers may be difficult to access). An illustrated terminology including detailed definitions and annotated illustrations is the focus of the classification system, the aim of which is to provide a framework with comparative examples to allow both modern and fossil leaves to be described and classified consistently.
