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."
Life was a bed of roses for Debra, the daughter of Alpha. That was until she had a one-night stand with Caleb. She was sure he was her mate as determined by Moon Goddess.

"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."
