Outlines of Structural and Physiological Botany

Outlines Of Structural And Physiological Botany by Arthur Henfrey. This work offers a concise survey of the present state of plant science, emphasizing the unity of plan that runs through the Vegetal Kingdom and the primacy of observation and generalization. It covers chemical composition of vegetables (inorganic constituents, organic constituents and essential organic compounds), the elementary structure of cells, tissues and organs, and the growth and propagation of plants. It details the axis, leaf, root, and stem, the anatomy of vascular bundles, epidermis, and the parenchyma, and the development of tissues and cells. It proceeds to the physiology of vegetation, including absorption, circulation, respiration, and assimilation, as well as secretion and the formation of chlorophyll, starch, gums, and resinous substances. The later chapters treat reproductive systems (flowerless and flowering plants), inflorescence, the flower in general, the calyx, corolla, stamens, pistil, ovules, and seeds, and the maturation of fruits. The Preface explains the aim to present knowledge up to date with clarity and prudence.
