This Essay first appeared in the ninth volume of the 'Journal of the Linnean Society,' published in 1865. It is here reproduced in a corrected and, I hope, clearer form, with some additional facts. The illustrations were drawn by my son, George Darwin. Fritz Muller, after the publication of my paper, sent to the Linnean Society (Journal, vol. ix., p. 344) some interesting observations on the climbing plants of South Brazil, to which I shall frequently refer.
Recently two important memoirs, chiefly on the difference in growth between the upper and lower sides of tendrils, and on the mechanism of the movements of twining-plants, by Dr. Hugo de Vries, have appeared in the 'Arbeiten des Botanischen Instituts in Wurzburg,' Heft. iii., 1873. These memoirs ought to be carefully studied by every one interested in the subject, as I can here give only references to the more important points. This excellent observer, as well as Professor Sachs, 1 attributes all the movements of tendrils to rapid growth along one side; but, from reasons assigned towards the close of my fourth chapter, I cannot persuade myself that this holds good with respect to those due to a touch. In order that the reader may know what points have interested me most, I may call his attention to certain tendril-bearing plants; for instance, Bignonia capreolata, Cobaea, Echinocystis, and Hanburya, which display as beautiful adaptations as can be found in any part of the kingdom of nature. It is, also, an interesting fact that intermediate states between organs fitted for widely different functions, may be observed on the same individual plant of Corydalis claviculata and the common vine; and these cases illustrate in a striking manner the principle of the gradual evolution of species.
Appendix to Preface (1882).
Since the publication of this Edition two papers by eminent botanists have appeared; Schwendener, 'Das Winden der Pflanzen' (Monatsberichte der Berliner Akademie, Dec. 1881), and J. Sachs, 'Notiz uber Schlingpflanzen' (Arbeiten des botanischen Instituts in Wurzburg, Bd. ii. p. 719, 1882). The view "that the capacity of revolving, on which most climbers depend, is inherent, though undeveloped, in almost every plant in the vegetable kingdom" ('Climbing Plants,' p. 205), has been confirmed by the observations on circumnutation since given in 'The Power of Movement in Plants.'
Errata.
On pp. 28, 32, 40, 53, statements are made with reference to the supposed acceleration of the revolving movement towards the light. It appears from the observations given in 'The Power of Movement in Plants,' p. 451, that these conclusions were drawn from insufficient observations, and are erroneous.

The Variation of Animals and Plants under Domestication is a book by Charles Darwin that was first published in January 1868. A large proportion of the book contains detailed information on the domestication of animals and plants but it also contains in Chapter XXVII a description of Darwin's theory of heredity which he called pangenesis.
First published in book form in 1877, this volume of Darwin's pioneering research on the heterostylous reproductive systems in flowering plants remains the basis of much exciting original research in the field of botany today. Darwin himself revealed, “I do not think anything in my scientific life has given me so much satisfaction as making out the meaning of the structure of these plants."
There was only one man in Raegan's heart, and it was Mitchel. In the second year of her marriage to him, she got pregnant. Raegan's joy knew no bounds. But before she could break the news to her husband, he served her divorce papers because he wanted to marry his first love. After an accident, Raegan lay in the pool of her own blood and called out to Mitchel for help. Unfortunately, he left with his first love in his arms. Raegan escaped death by the whiskers. Afterward, she decided to get her life back on track. Her name was everywhere years later. Mitchel became very uncomfortable. For some reason, he began to miss her. His heart ached when he saw her all smiles with another man. He crashed her wedding and fell to his knees while she was at the altar. With bloodshot eyes, he queried, "I thought you said your love for me is unbreakable? How come you are getting married to someone else? Come back to me!"
One year into marriage, Yvonne realized she was nothing more than a substitute for someone else's memory. When his true love reappeared, Julian tossed a divorce contract her way. "She's back. We're finished," he said flatly. The secret of her pregnancy stayed hidden. Yvonne fought the urge to cry, signed her freedom, and disappeared. Five years on, cameras flashed as Yvonne, radiant in red, strode across a film festival stage with her bright-eyed son. Julian's hands clenched as he watched. "Sir, the boy's four and a half," whispered his shaken assistant. Then, he rushed to the film set only to witness an A-list actor gently wrapping his arm around Yvonne's waist. "I've booked your favorite restaurant for tonight's celebration." The little boy blinked his innocent eyes at Julian, asking, "Who are you? One of my mom's crazy admirers?" He cornered her in the dressing room, his voice hoarse as he said, "Let's remarry." Her lips curled slightly, but the smile didn't reach her eyes. "The curtain's down; it's time to end this scene." But this time, he wasn't letting go.
