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."

COALESCENCE OF THE FIVE SERIES BOOK ONE: THE 5-TIME REJECTED GAMMA & THE LYCAN KING BOOK TWO: THE ROGUES WHO WENT ROGUE BOOK THREE: THE INDOMITABLE HUNTRESS & THE HARDENED DUKE *** BOOK ONE: After being rejected by 5 mates, Gamma Lucianne pleaded with the Moon Goddess to spare her from any further mate-bonds. To her dismay, she is being bonded for the sixth time. What’s worse is that her sixth-chance mate is the most powerful creature ruling over all werewolves and Lycans - the Lycan King himself. She is certain, dead certain, that a rejection would come sooner or later, though she hopes for it to be sooner. King Alexandar was ecstatic to meet his bonded mate, and couldn’t thank their Goddess enough for gifting him someone so perfect. However, he soon realizes that this gift is reluctant to accept him, and more than willing to sever their bond. He tries to connect with her but she seems so far away. He is desperate to get intimate with her but she seems reluctant to open up to him. He tries to tell her that he is willing to commit to her for the rest of his life but she doesn’t seem to believe him. He is pleading for a chance: a chance to get to know her; a chance to show her that he’s different; and a chance to love her. But when not-so-subtle crushes, jealous suitors, self-entitled Queen-wannabes, an old flame, a silent protector and a past wedding engagement threaten to jeopardize their relationship, will Lucianne and Xandar still choose to be together? Is their love strong enough to overcome everything and everyone? Or will Lucianne resort to enduring a sixth rejection from the one person she thought she could entrust her heart with?
"There will be no falling in love, we will only act as a loving couple when we are in public, we will share a room to make it believable, but no intimacy, touching is off-limits. We'll only have sex once a month, and that's solely to produce an heir. You won't interfere in my business, and I won't interfere in yours. You will be my wife in every sense and you will not be involved with any other man," he said, arrogance seeping from every word. I watch his mouth move, I'm not ready to fall in love with any man, especially not one as arrogant and egoistic as him. I can handle acting as a loving couple, and as for intimacy once a month. I can agree to that just to satisfy my sexual cravings with no strings attached. "Where can I sign?" I asked since I had nothing to lose. *** Nadine's wedding dreams turned to nightmares when she caught her sister and fiancé cheating! With a secret recording, she's ready for revenge.
