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."
Corinne devoted three years of her life to her boyfriend, only for it to all go to waste. He saw her as nothing more than a country bumpkin and left her at the altar to be with his true love. After getting jilted, Corinne reclaimed her identity as the granddaughter of the town's richest man, inherited a billion-dollar fortune, and ultimately rose to the top. But her success attracted the envy of others, and people constantly tried to bring her down. As she dealt with these troublemakers one by one, Mr. Hopkins, notorious for his ruthlessness, stood by and cheered her on. "Way to go, honey!"
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.
Dayna had worshiped her husband, only to watch him strip her late mother's estate and lavish devotion on another woman. After three miserable years, he discarded her, and she lay broken-until Kristopher, the man she once betrayed, dragged her from the wreckage. He now sat in a wheelchair, eyes like tempered steel. She offered a pact: she would mend his legs if he helped crush her ex. He scoffed, yet signed on. As their ruthless alliance caught fire, he uncovered her other lives-healer, hacker, pianist-and her numb heart stirred. But her groveling ex crawled back. "Dayna, you were my wife! How could you marry someone else? Come back!"
Kaelyn devoted three years tending to her husband after a terrible accident. But once he was fully recovered, he cast her aside and brought his first love back from abroad. Devastated, Kaelyn decided on a divorce as people mocked her for being discarded. She went on to reinvent herself, becoming a highly sought-after doctor, a champion racer, and an internationally renowned architectural designer. Even then, the traitors sneered in disdain, believing Kaelyn would never find someone. But then the ex-husband’s uncle, a powerful warlord, returned with his army to ask for Kaelyn’s hand in marriage.
Seven years ago, my fiancé, Don Dante Moretti, sent me to prison to take the fall for my adopted sister, Chiara. He called it a gift—a way to protect me from a worse fate. Today, he picked me up from prison only to abandon me at my family's estate. His reason? Chiara was having another one of her "episodes." My parents then informed me I'd be staying in the third-floor storage room, so as not to disturb the fragile girl who stole my life. They celebrated her "recovery" with a lavish dinner party, while I was treated like a ghost. When I refused to join, my mother hissed that I was ungrateful, and my father called me jealous. They assumed I couldn't understand their venomous whispers. But prison was my university. I learned Spanish. I understood every word. It was then I realized I wasn't just a sacrifice; I was disposable. The love I once felt for all of them had turned to ash. That night, in the dusty storage room, I logged onto an encrypted channel I'd set up years ago. A single message was waiting: "The offer stands. Do you accept?" My hands, scarred and steady, typed back, "I accept."
A year into the marriage, Thea rushed home with radiant happiness-she was pregnant. Jerred barely glanced up. "She's back." The woman he'd never let go had returned, and he forgot he was a husband, spending every night at her hospital bed. Thea forced a smile. "Let's divorce." He snapped, "You're jealous of someone who's dying?" Because the woman was terminal, he excused every jab and made Thea endure. When love went cold, she left the papers and stormed off. He locked down the city and caught her at the airport, eyes red, dropping to his knees. "Honey, where are you going with our child?"
