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."
Trigger/Content Warning: This story contains mature themes and explicit content intended for adult audiences(18+). Reader discretion is advised. It includes elements such as BDSM dynamics, explicit sexual content, toxic family relationships, occasional violence and strong language. This is not a fluffy romance. It is intense, raw and messy, and explores the darker side of desire. ***** "Take off your dress, Meadow." "Why?" "Because your ex is watching," he said, leaning back into his seat. "And I want him to see what he lost." ••••*••••*••••* Meadow Russell was supposed to get married to the love of her life in Vegas. Instead, she walked in on her twin sister riding her fiance. One drink at the bar turned to ten. One drunken mistake turned into reality. And one stranger's offer turned into a contract that she signed with shaking hands and a diamond ring. Alaric Ashford is the devil in a tailored Tom Ford suit. Billionaire CEO, brutal, possessive. A man born into an empire of blood and steel. He also suffers from a neurological condition-he can't feel. Not objects, not pain, not even human touch. Until Meadow touches him, and he feels everything. And now he owns her. On paper and in his bed. She wants him to ruin her. Take what no one else could have. He wants control, obedience... revenge. But what starts as a transaction slowly turns into something Meadow never saw coming. Obsession, secrets that were never meant to surface, and a pain from the past that threatens to break everything. Alaric doesn't share what's his. Not his company. Not his wife. And definitely not his vengeance.

To most, Verena passed for a small-town clinic doctor; in truth, she worked quiet miracles. Three years after Isaac fell hopelessly for her and kept vigil through lonely nights, a crash left him in a wheelchair and stripped his memory. To keep him alive, Verena married him, only to hear, "I will never love you." She just smiled. "That works out-I'm not in love with you, either." Entangled in doubt, he recoiled from hope, yet her patience held him fast-kneeling to meet his eyes, palm warm on his hair, steadying him-until her glowing smile rekindled feelings he believed gone forever.
