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."
After a one-night stand with a stranger, Roselyn woke up to find only a bank card without a PIN number. Still in a daze, she was detained on charges of theft. Just as the handcuffs were about to close, the mysterious man reappeared, holding her pregnancy report. "You're pregnant with my child," he said coldly. Shocked, Roselyn was whisked away in a helicopter to the presidential palace, where she learned the truth: the man from that night was none other than the country's most powerful and influential leader!
When her half-sister stole her fiancé, scarred her face, and threw her from a skyscraper, Amelia thought it was the end-until fate gave her a second chance. Reborn with bitter clarity, she vowed not to repeat the same mistakes. In her past life, she had been kind to a fault; now, she would wear a mask of innocence to outmaneuver every snake in the grass. One by one, she tore down their schemes-leaving her treacherous sister begging, her stepmother pleading, her worthless father groveling, and her ex-fiancé crawling back. Her response was a cold smirk and two words: "Get lost." But the one thing she never anticipated was crossing paths with Damien Taylor-the most powerful and untouchable man in the capital-on the very first day of her new life. They said he was ruthless, ice-cold, immune to any woman's charm. Amelia believed it. until she learned the truth: the man was dangerously cunning. "Miss Johnson, I saved you. How about dinner?" "Miss Johnson, I helped you. Don't you owe me a favor?" Backed against the wall, Amelia felt his low voice vibrate through her: "You owe me too much, Amelia. It's time to pay up-starting with you." Only much later would she realize. she'd been owing him all along.
Gianna Benton, a woman who came from a great family, a family with ancient history, had always lived a life that's overshadowed by her younger sister, Quinn. After her unfair death with her unborn baby at the hands of the man she loved, Gianna got reborn. Now with the opportunity to live again, Gianna rejects her mate and gives herself to alpha Axel, falling into an unexpected contract marriage. Both plans to use each other, and falling in love isn't part of the deal for them. Gianna plans to get her revenge on her former lover, alpha Nathan, who killed her in the past because of her younger sister, but surprisingly to her, alpha Nathan wants his mate back, and Gianna is determined not to let the past repeat itself. ------------------------------------------------- "Is this hell?" "Gianna, what's wrong with you? I know that you are excited, but you need to stop acting weird." Mom said. I reach out my hands to touch her face, but she slaps my hands away. This is real, I thought. Somehow, I have gone back in time to the day I got married to Alpha Nathan. "I need to take a picture of you, but I can't do it without your sister. Wait here for me while I go get your sister." Mom left the room, leaving me alone with my thoughts. My hands formed a fist in anger as I thought of Quinn and Alpha Nathan. I don't know how I have traveled back to the past, but I'm not going to let myself make the same mistake I did in my past life; I'm not getting married to alpha Nathan. No matter what, I need to put a stop to this wedding.
Elliana, the unfavored "ugly duckling" of her family, was humiliated by her stepsister, Paige, who everyone admired. Paige, engaged to the CEO Cole, was the perfect woman-until Cole married Elliana on the day of the wedding. Shocked, everyone wondered why he chose the "ugly" woman. As they waited for her to be cast aside, Elliana stunned everyone by revealing her true identity: a miracle healer, financial mogul, appraisal prodigy, and AI genius. When her mistreatment became known, Cole revealed Elliana's stunning, makeup-free photo, sending shockwaves through the media. "My wife doesn't need anyone's approval."
Her ex-husband declared, "The person I admired most was that legendary racer." She smiled thinly. "Hate to break it to you-that was me." He said, "Jealous I blew a fortune on a world-famous jeweler for Violet?" She let out a cool laugh. "Funny, that designer trained under me." He scoffed, "Buying a dying firm won't put you in my league. Snap out of it." She shrugged. "Weird-I just steered your company off a cliff." Stunned, he blurted out, "Baby, come back. I'll love you forever." She wrinkled her nose. "Hard pass. Keep your cheap love." Then she took a mogul's arm and never looked back.
