Outlines of Lessons in Botany, Part I; from Seed to Leaf But twiners have one disadvantage: to rise ten feet they must produce fifteen feet of stem or thereabouts, according to the diameter of the support, and the openness or closeness of the coil. Darwiniana; Essays and Reviews Pertaining to Darwinism If we consider leaf-climbers alone, the idea that they were primordially twiners is forcibly suggested. The Movements and Habits of Climbing Plants It is, however, probable, from reasons which I have assigned in my memoir, that this will have occurred only with plants which had already acquired the power of revolving, and had thus become twiners. The Origin of Species by means of Natural Selection, 6th Edition In accordance with this view we find LEAF-CLIMBERS, which may be looked on as incipient tendril-bearers, occurring in the same genera with simple twiners. Darwin and Modern Science On the view here given, it may be asked, Why have the species which were aboriginally twiners been converted in so many groups into leaf- climbers or tendril-bearers? The Movements and Habits of Climbing Plants This is the case: thus the several leaf-climbing species of the Antirrhineae, of Solanum, Cocculus, and Gloriosa, have within the same family and even within the same genus, relatives which are twiners. The Movements and Habits of Climbing Plants Several leaf-climbing genera are closely allied to other genera which are simple twiners. The Movements and Habits of Climbing Plants Has, for instance, any tendril- bearing plant assumed its present structure without having previously existed as a leaf-climber or a twiner? The Movements and Habits of Climbing Plants One of these is the finding of a support, and this is common to twiners and tendrils. Darwin and Modern Science The internodes of all, without exception, revolve in exactly the same manner as twiners; some few can still twine well, and many others in an imperfect manner. The Movements and Habits of Climbing Plants These roots therefore seem to be true twiners, though they use their powers to descend, instead of to ascend like twining plants. The Movements and Habits of Climbing Plants From analogous reasons, it is probable that all tendril-bearers were primordially twiners, that is, are the descendants of plants having this power and habit. The Movements and Habits of Climbing Plants Lastly, a species of Bignonia is at the same time both a leaf-climber and a tendril-bearer; and other closely allied species are twiners. The Movements and Habits of Climbing Plants We have seen in the Table in the first chapter that Mikania scandens is a regular twiner, and F. Muller informs me that in S. Brazil there is another species which is a leaf-climber. The Movements and Habits of Climbing Plants Differently from most twiners, there is a strong tendency in the same shoot to revolve first in one and then in an opposite direction. The Movements and Habits of Climbing Plants SOLANACEAE.—Solanum jasminoides.—Some of the species in this large genus are twiners; but the present species is a true leaf-climber. The Movements and Habits of Climbing Plants In the two other families I can hear of no twiners; and the internodes rarely have the power of revolving, this power being confined to the tendrils. The Movements and Habits of Climbing Plants CLEMATIS.—C. glandulosa.—The thin upper internodes revolve, moving against the course of the sun, precisely like those of a true twiner, at an average rate, judging from three revolutions, of 3 hrs.
