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."
Gabriela learned her boyfriend had been two-timing her and writing her off as a brainless bimbo, so she drowned her heartache in reckless adventure. One sultry blackout night she tumbled into bed with a stranger, then slunk away at dawn, convinced she'd succumbed to a notorious playboy. She prayed she'd never see him again. Yet the man beneath those sheets was actually Wesley, the decisive, ice-cool, unshakeable CEO who signed her paychecks. Assuming her heart was elsewhere, Wesley returned to the office cloaked in calm, but every polite smile masked a dark surge of possessive jealousy.
After hiding her true identity throughout her three-year marriage to Colton, Allison had committed wholeheartedly, only to find herself neglected and pushed toward divorce. Disheartened, she set out to rediscover her true self-a talented perfumer, the mastermind of a famous intelligence agency, and the heir to a secret hacker network. Realizing his mistakes, Colton expressed his regret. "I know I messed up. Please, give me another chance." Yet, Kellan, a once-disabled tycoon, stood up from his wheelchair, took Allison's hand, and scoffed dismissively, "You think she'll take you back? Dream on."
"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."
I just got my billionaire husband to sign our divorce papers. He thinks it's another business document. Our marriage was a business transaction. I was his secretary by day, his invisible wife by night. He got a CEO title and a rebellion against his mother; I got the money to save mine. The only rule? Don't fall in love. I broke it. He didn't. So I'm cashing out. Thirty days from now, I'm gone. But now he's noticing me. Touching me. Claiming me. The same man who flaunts his mistresses is suddenly burning down a nightclub because another man insulted me. He says he'll never let me go. But he has no idea I'm already halfway out the door. How far will a billionaire go to keep a wife he never wanted until she tried to leave?
Vivian clutched her Hermès bag, her doctor's words echoing: "Extremely high-risk pregnancy." She hoped the baby would save her cold marriage, but Julian wasn't in London as his schedule claimed. Instead, a paparazzi photo revealed his early return-with a blonde woman, not his wife, at the private airport exit. The next morning, Julian served divorce papers, callously ending their "duty" marriage for his ex, Serena. A horrifying contract clause gave him the right to terminate her pregnancy or seize their child. Humiliated, demoted, and forced to fake an ulcer, Vivian watched him parade his affair, openly discarding her while celebrating Serena. This was a calculated erasure, not heartbreak. He cared only for his image, confirming he would "handle" the baby himself. A primal rage ignited her. "Just us," she whispered to her stomach, vowing to sign the divorce on her terms, keep her secret safe, and walk away from Sterling Corp for good, ready to protect her child alone.
Lyric had spent her life being hated. Bullied for her scarred face and hated by everyone-including her own mate-she was always told she was ugly. Her mate only kept her around to gain territory, and the moment he got what he wanted, he rejected her, leaving her broken and alone. Then, she met him. The first man to call her beautiful. The first man to show her what it felt like to be loved. It was only one night, but it changed everything. For Lyric, he was a saint, a savior. For him, she was the only woman that had ever made him cum in bed-a problem he had been battling for years. Lyric thought her life would finally be different, but like everyone else in her life, he lied. And when she found out who he really was, she realized he wasn't just dangerous-he was the kind of man you don't escape from. Lyric wanted to run. She wanted freedom. But she desired to navigate her way and take back her respect, to rise above the ashes. Eventually, she was forced into a dark world she didn't wish to get involved with.
