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."
Eighteen days after giving up on Brendan Maynard, Jayde Rosario cut off her waist-length hair and called her father, announcing her decision to move to California and attend UC Berkeley. Her father, surprised, asked about the sudden change, reminding her how she' d always insisted on staying with Brendan. Jayde forced a laugh, revealing the painful truth: Brendan was getting married, and she, his stepsister, could no longer cling to him. That night, she tried to tell Brendan about her college acceptance, but his fiancée, Chloie Ellis, interrupted with a bubbly call, and Brendan' s tender words to Chloie twisted a knife in Jayde' s heart. She remembered how his tenderness used to be hers alone, how he had protected her, and how she had poured out her heart to him in a diary and a love letter, only for him to explode, tearing the letter and yelling, "I'm your brother!" He had stormed out, leaving her to painstakingly tape the shredded pieces back together. Her love, however, didn't die, not even when he brought Chloie home and told her to call her "sister-in-law." Now, she understood. She had to put that fire out herself. She had to dig Brendan out of her heart.
"Stella once savored Marc's devotion, yet his covert cruelty cut deep. She torched their wedding portrait at his feet while he sent flirty messages to his mistress. With her chest tight and eyes blazing, Stella delivered a sharp slap. Then she deleted her identity, signed onto a classified research mission, vanished without a trace, and left him a hidden bombshell. On launch day she vanished; that same dawn Marc's empire crumbled. All he unearthed was her death certificate, and he shattered. When they met again, a gala spotlighted Stella beside a tycoon. Marc begged. With a smirk, she said, ""Out of your league, darling."
Abandoned as a child and orphaned by murder, Kathryn swore she'd reclaim every shred of her stolen birthright. When she returned, society called her an unpolished love-child, scoffing that Evan had lost his mind to marry her. Only Evan knew the truth: the quiet woman he cradled like porcelain hid secrets enough to set the city trembling. She doubled as a legendary healer, an elusive hacker, and the royal court's favorite perfumer. At meetings, the directors groaned at the lovey-dovey couple, "Does she really have to be here?" Evan shrugged. "Happy wife, happy life." Soon her masks fell, and those who sneered bowed in awe.
Rejected by her mate, who had been her long-time crush, Jasmine felt utterly humiliated. Seeking solace, she headed to a party to drown her sorrows. But things took a turn for the worse when her friends issued a cruel dare: kiss a stranger or beg her mate for forgiveness. With no other choice, Jasmine approached a stranger and kissed him, thinking that would be the end of it. However, the stranger unexpectedly wrapped his arms around her waist and whispered in her ear, "You're mine!" He growled, his words sending shivers down her spine. And then, he offered her a solution that would change everything...
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.
My husband was in the shower, the sound of water a familiar rhythm to our mornings. I was just placing a cup of coffee on his desk, a small ritual in our five years of what I thought was a perfect marriage. Then, an email notification flashed on his laptop: "You're invited to the Christening of Leo Thomas." Our last name. The sender: Hayden Cleveland, a social media influencer. An icy dread settled in. It was an invitation for his son, a son I didn't know existed. I went to the church, hidden in the shadows, and saw him holding a baby, a little boy with his dark hair and eyes. Hayden Cleveland, the mother, leaned on his shoulder, a picture of domestic bliss. They looked like a family. A perfect, happy family. My world crumbled. I remembered him refusing to have a baby with me, citing work pressure. All his business trips, the late nights-were they spent with them? The lie was so easy for him. How could I have been so blind? I called the Zurich Architectural Fellowship, a prestigious program I had deferred for him. "I' d like to accept the fellowship," I said, my voice eerily calm. "I can leave immediately."
