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."
"It was just one night stand, and now I'm pregnant with triplets? Gosh!" Josephine Jade never thought that she would have to run away from her own family while pregnant. She was alone, without money, without connections, with three fetuses in her stomach. How can she survive? However, Josephine couldn't give up now, until she managed to reclaim her arbitrarily seized property and get back at everyone who tried to get rid of her. A sick child, a past crush that comes back, a mysterious eccentric man, and a family that hates her, will weave together the journey of Josephine Jade's new life. "You have no right to separate me from my children, you bastard! I will survive and you will submit to me. Just watch!"
"I will marry you. Wait for me!" Mabel woke up. She had that dream again. In her dream, a man said he would marry her. Just a dream. Five years ago, she was set up by her stepsister and became pregnant out of wedlock. She lost everything, including her baby. Five years later, she was forced to marry her stepsister's fiance, Jayden, who was sick and going to pass away. Having no choice, Mabel decided to marry Jayden, not expecting that Jayden was the man...
Five years into marriage, Hannah caught Vincent slipping into a hotel with his first love-the woman he never forgot. The sight told her everything-he'd married her only for her resemblance to his true love. Hurt, she conned him into signing the divorce papers and, a month later, said, "Vincent, I'm done. May you two stay chained together." Red-eyed, he hugged her. "You came after me first." Her firm soon rocketed toward an IPO. At the launch, Vincent watched her clasp another man's hand. In the fitting room, he cornered her, tears burning in his eyes. "Is he really that perfect? Hannah, I'm sorry... marry me again."
For financial gain, Isla's father married her to Theodore, a comatose heir. Unconscious, he duped her; awake, he claimed she'd groped him and flirted nonstop. When she discovered she was pregnant, his "lost love" appeared, and he slid divorce papers across the bed. Isla slapped his hush money back and left. They crossed paths again, with Isla lauded as a hacker, race champ, composer, and screenwriter-and the elusive doctor Theodore coveted. He begged, "One more chance." She said, "Prove it with your life." He did, but what he didn't know was that she always knew the "lost love" was only a decoy.
Sunlit hours found their affection glimmering, while moonlit nights ignited reckless desire. But when Brandon learned his beloved might last only half a year, he coolly handed Millie divorce papers, murmuring, "This is all for appearances; we'll get married again once she's calmed down." Millie, spine straight and cheeks dry, felt her pulse go hollow. The sham split grew permanent; she quietly ended their unborn child and stepped into a new beginning. Brandon unraveled, his car tearing down the street, unwilling to let go of the woman he'd discarded, pleading for her to look back just once.
A twist of fate bound Allison to Derek in marriage-she, a powerful heiress with countless hidden identities; he, the city's most admired man, now lying silent in a coma. For three years, Allison used her unmatched medical skills to heal him, all while quietly falling in love. But when Derek's long-lost love returned from abroad, he handed Allison divorce papers without a second thought. Resolved to stop chasing shadows, Allison signed the papers and turned her back on love-rising to fame as a dazzling force in business, medicine, and more. Only when she stood high above the world did Derek finally see her worth. He knelt before her, eyes brimming with regret. "Will you take me back?" he whispered.
