The Movements and Habits of Climbing Plants Canes short, slender, dark reddish-brown; nodes flattened; internodes short; tendrils intermittent, bifid or trifid. Manual of American Grape-Growing The richer and the more abundant the supply of the food solution, the greater the vegetative activity, the larger the leaves and the larger and stouter the internodes.

Manual of American Grape-Growing The cion is made with about two and one-half inches of internode below the bud and one-half inch above, a sharp knife being the best tool for making the cuts. Manual of American Grape-Growing The young internodes sweep large circles, one being completed in 2 hrs. The Movements and Habits of Climbing Plants The thirty-sixth revolution was performed at the usual rate; so was the last or thirty-seventh, but it was not completed; for the internode suddenly became upright, and after moving to the centre, remained motionless. The Movements and Habits of Climbing Plants Bignonia capreolata.—We now come to a species having tendrils of a different type; but first for the internodes. The Movements and Habits of Climbing Plants Canes long, numerous, thick, dark reddish-brown, heavily pubescent, spiny; nodes prominent; internodes short; tendrils continuous, long, bifid. Manual of American Grape-Growing I may add that the tendrils, or the internodes, or both, of Vicia sativa revolve. The Movements and Habits of Climbing Plants Whether the internodes likewise revolve I did not observe. The Movements and Habits of Climbing Plants With the Hop we have seen that three internodes were at the same time revolving; and this was the case with most of the plants observed by me. The Movements and Habits of Climbing Plants The two or three upper internodes, whilst young, steadily revolve; those on one plant made two circles, against the course of the sun, in 3 hrs. The Movements and Habits of Climbing Plants Canes long, thick, dark reddish-brown; nodes enlarged, flattened; internodes long; shoots pubescent; tendrils continuous, long, bifid, sometimes trifid. Manual of American Grape-Growing In certain species of Tropaeolum, both the spontaneous movements of the internodes and the sensitiveness of the petioles have become much enfeebled, and in one species have been completely lost. The Movements and Habits of Climbing Plants The main petiole of the leaf, whilst young, moves spontaneously, and follows nearly the same irregular course and at about the same rate as the internodes. The Movements and Habits of Climbing Plants As each internode loses from age its power of revolving, it likewise loses its power of spirally twining. The Movements and Habits of Climbing Plants The internode afterwards straightens itself, excepting the part in actual contact with the stick. The Movements and Habits of Climbing Plants Canes dark brown with light bloom, surface roughened; nodes enlarged, flattened; internodes short; tendrils intermittent, short, bifid or trifid. Manual of American Grape-Growing I rubbed some internodes one day on one side, and the next day either on the opposite side or at right angles to the first side; and the curvature was always towards the rubbed side. The Movements and Habits of Climbing Plants The internodes in one case made two circles, each in 2 hrs. The Movements and Habits of Climbing Plants With all, if in full health, two internodes revolved; so that by the time the lower one ceased to revolve, the one above was in full action, with a terminal internode just commencing to move. The Movements and Habits of Climbing Plants By these combined movements of the internodes, petioles, and grapnel- like tendrils, the latter are soon brought into contact with surrounding objects. The Movements and Habits of Climbing Plants Canes short, slender, brown with a red tinge; nodes enlarged, flattened; internodes short; tendrils continuous, short, bifid. Manual of American Grape-Growing An internode bearing immature tendrils made two revolutions, each in 3 hrs. The Movements and Habits of Climbing Plants Such strongly marked interruptions in the movements of the internodes I have observed in hardly any other plant. The Movements and Habits of Climbing Plants This action of the light is remarkable, when we reflect how little the leaves are developed on the young and thin revolving internodes. The Movements and Habits of Climbing Plants By these combined movements of the young internodes, petioles, and tendrils, a considerable space is swept in search of a support. The Movements and Habits of Climbing Plants Canes numerous, dark brown; nodes flattened; internodes short; tendrils continuous, trifid or bifid. Manual of American Grape-Growing I painted a red line on the straight internodes of a Humulus, Mikania, Ceropegia, Convolvulus, and Phaseolus, and saw it become twisted as the plant wound round a stick. The Movements and Habits of Climbing Plants With the majority of tendril-bearing plants the young internodes revolve in more or less broad ellipses, like those made by twining plants; but the figures described, when carefully traced, generally form irregular ellipsoidal spires. The Movements and Habits of Climbing Plants An upper internode made three revolutions, following the sun, at an average rate of 1 hr. The Movements and Habits of Climbing Plants The mature tendrils of Bignonia littoralis move much slower than the internodes. The Movements and Habits of Climbing Plants Canes short, few, slender, brownish; nodes enlarged; internodes short; tendrils intermittent, bifid. Manual of American Grape-Growing In B. littoralis the tendrils, petioles, and internodes, all revolve spontaneously. The Movements and Habits of Climbing Plants In the allied Eccremocarpus the internodes, petioles, and much- branched tendrils all spontaneously revolve together. The Movements and Habits of Climbing Plants I allowed the top to grow out almost horizontally to the length of 31 inches; this now consisted of three long internodes, terminated by two short ones. The Movements and Habits of Climbing Plants To ascertain more precisely what amount of movement each internode underwent, I kept a potted plant, during the night and day, in a well-warmed room to which I was confined by illness. The Movements and Habits of Climbing Plants Canes short, few in number, slender; nodes enlarged; internodes very short; tendrils continuous, bifid or trifid. Manual of American Grape-Growing After the twenty-first revolution, the penultimate internode was 2.5 inches long, and probably revolved in a period of about three hours. The Movements and Habits of Climbing Plants When the movement ceased, the lower internode was 9 inches, and the penultimate 6 inches in length; so that, from the twenty-seventh to thirty-seventh revolutions inclusive, three internodes were at the same time revolving. The Movements and Habits of Climbing Plants Moreover, the revolving movement commenced in the young internode before any twisting of its axis could be detected. The Movements and Habits of Climbing Plants This swaying movement was certainly due to the movement of the lower internodes, which, however, had not force sufficient to swing the whole shoot round the central supporting stick. The Movements and Habits of Climbing Plants Canes long, thick, cylindrical; internodes long; tendrils continuous, trifid. Manual of American Grape-Growing The two or three, or even more, internodes which are first formed above the cotyledons, or above the root-stock of a perennial plant, do not move; they can support themselves, and nothing superfluous is granted. The Movements and Habits of Climbing Plants Tropaeolum azureum.—An upper internode made four revolutions, following the sun, at an average rate of 1 hr. The Movements and Habits of Climbing Plants A line painted along the convex surface of a revolving internode becomes first lateral, then concave, then lateral and ultimately again convex. The Movements and Habits of Climbing Plants Tropaeolum peregrinum.—The first-formed internodes of a young plant did not revolve, resembling in this respect those of a twining plant. The Movements and Habits of Climbing Plants Canes slender, dark reddish-brown; nodes flattened; internodes short, bifid. Manual of American Grape-Growing Clematis microphylla, var. leptophylla.—The long and thin internodes of this Australian species revolve sometimes in one direction and sometimes in an opposite one, describing long, narrow, irregular ellipses or large circles. The Movements and Habits of Climbing Plants In an older plant the four upper internodes made three irregular revolutions, in a course opposed to the sun, at an average rate of 1 hr. The Movements and Habits of Climbing Plants They are thus enabled to catch hold of any twig with which they may be brought into contact by the revolving movement of the internodes. The Movements and Habits of Climbing Plants The short and stiff internodes revolve irregularly, describing small oval figures. The Movements and Habits of Climbing Plants Canes short, numerous, slender, dark brown; nodes enlarged; internodes short; tendrils intermittent, short, bifid. Manual of American Grape-Growing Tropaeolum tuberosum.—On a plant nine inches in height, the internodes did not move at all; but on an older plant they moved irregularly and made small imperfect ovals. The Movements and Habits of Climbing Plants A young internode made two circles, each in 1 hr. The Movements and Habits of Climbing Plants The young internodes, likewise revolved irregularly in ellipses or spires; so that by these combined movements a considerable space was swept for a support. The Movements and Habits of Climbing Plants With due deference to this great observer, I think he was mistaken, owing to his not having secured the internodes. The Movements and Habits of Climbing Plants Canes short, few, slender, dark green with an ash-gray tinge, surface covered with thin bloom, often roughened with a few small warts; nodes much enlarged, strongly flattened; internodes short; tendrils intermittent, bifid or trifid. Manual of American Grape-Growing A young upper internode revolved, judging from three revolutions, at an average rate of 1 hr. The Movements and Habits of Climbing Plants But their movement is slower and much less regularly elliptical than that of the internodes. The Movements and Habits of Climbing Plants I observed thirty-five revolutions of the internodes and tendrils; the slowest rate was 2 hrs. and the average rate, with no great fluctuations, 1 hr. The Movements and Habits of Climbing Plants In our present species a young internode, placed in front of a window, made three narrow ellipses, transversely to the direction of the light, at an average rate of 2 hrs. The Movements and Habits of Climbing Plants Canes long, numerous, thick, reddish-brown; nodes enlarged, flattened; internodes long; tendrils intermittent, long, trifid. Manual of American Grape-Growing The tendrils, besides being carried by the moving petioles and internodes, themselves move spontaneously; and the opposite tendrils occasionally move in opposite directions. The Movements and Habits of Climbing Plants I believe Dutrochet was misled by not having secured the internodes, and by having observed a plant of which the internodes and tendrils no longer curved in harmony together, owing to inequality of age. The Movements and Habits of Climbing Plants The two uppermost internodes alone revolve; and as soon as the lower one grows old, only its upper part continues to move. The Movements and Habits of Climbing Plants If so, we have the rare case of neither internodes nor tendrils revolving. The Movements and Habits of Climbing Plants Canes thick, dark brown; nodes enlarged, flattened; internodes short; tendrils intermittent, bifid to trifid. Manual of American Grape-Growing We may suspect that, owing to the principle of correlation, the power of movement has been transferred to the flower-peduncles from the young internodes, and sensitiveness from the young petioles. The Movements and Habits of Climbing Plants The young internodes are in continual movement, which is considerable in extent, but very irregular; a zigzag line, or a spire crossing itself; or a figure of 8 being formed. The Movements and Habits of Climbing Plants By the combined movements of the internodes and peduncles, one of the two short hooked tendrils, sooner or later, catches hold of some twig or branch, and then it curls round and securely grasps it. The Movements and Habits of Climbing Plants At each stage of growth only the two upper internodes revolved. The Movements and Habits of Climbing Plants Canes long, numerous, thick, dark brown; nodes enlarged, flattened; internodes short; tendrils continuous, long, bifid or trifid. Manual of American Grape-Growing Young internodes alone are sensitive, and these are sensitive on all sides along their whole length. The Movements and Habits of Climbing Plants From the analogy of Fumaria and Corydalis, I have no doubt that the internodes of Adlumia have the power of revolving. The Movements and Habits of Climbing Plants For the internodes of the majority revolve; and, in a few species, the flexible stem still retains the capacity of spirally twining round an upright stick. The Movements and Habits of Climbing Plants On the other hand, with most of the species of Bignonia and the Eccremocarpus, the internodes, tendrils, and petioles all revolved. The Movements and Habits of Climbing Plants Canes long, numerous, thick, dark brown; nodes enlarged, flattened; internodes long; tendrils intermittent, long, bifid. Manual of American Grape-Growing The leaf in this case followed an irregular course, like that made by the internodes. The Movements and Habits of Climbing Plants In all the species observed by me, with one exception, the young internodes revolve more or less regularly, in some cases as regularly as those of a twining plant. 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 The young internodes of the Lophospermum as well as the petioles are sensitive to a touch, and by their combined movement seize an object. The Movements and Habits of Climbing Plants Canes long, dark reddish-brown; nodes enlarged, flattened; internodes short; tendrils intermittent, long, bifid or trifid. Manual of American Grape-Growing After the young internodes have twined round a stick, their continued growth causes them to slip a little upwards. The Movements and Habits of Climbing Plants A mature tendril made an ellipse in 6 hrs.; so that it moved much more slowly than the internodes. The Movements and Habits of Climbing Plants 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 We thus see that the young internodes, the petioles, and the tendrils all continue revolving together, but at different rates. The Movements and Habits of Climbing Plants Canes short, dark brown; nodes enlarged, flattened; internodes short; tendrils continuous or intermittent, long, bifid to trifid. Manual of American Grape-Growing The internodes of the stem are not at all sensitive, which makes Mohl's statement that they are sometimes converted into tendrils the more surprising, not to say improbable. The Movements and Habits of Climbing Plants The whole leaf with its tendril, as well as the young upper internodes, revolves vigorously and quickly, though irregularly, and thus sweeps a wide space. The Movements and Habits of Climbing Plants In most Bignonias, Eccremocarpus Mutisia, and the Fumariaceae, the internodes, petioles and tendrils all move harmoniously together. The Movements and Habits of Climbing Plants The ellipses or circles swept by the summits of the internodes are about three inches in diameter; whilst those swept by the tips of the tendrils, are from 15 to 16 inches in diameter. The Movements and Habits of Climbing Plants Canes variable in length and thickness, dark reddish-brown; nodes enlarged, flattened; internodes short; tendrils continuous, sometimes intermittent, bifid or trifid. Manual of American Grape-Growing This false appearance is apparently due to the internodes and tendrils all curving and moving harmoniously together. The Movements and Habits of Climbing Plants The lower part moves but little and the petiole not at all; nor do the internodes revolve; so that here we have the tendril alone moving. The Movements and Habits of Climbing Plants There is, however, in many cases this unimportant difference, that the curving tendril is separated from the curving internode by a rigid petiole. The Movements and Habits of Climbing Plants The young internodes, on the other hand, revolve in ellipses, and carry with them the tendrils. The Movements and Habits of Climbing Plants Canes long, numerous, slender, dark reddish-brown; nodes enlarged, flattened; internodes long; tendrils intermittent, trifid or bifid. Manual of American Grape-Growing The tendrils, on the other hand, when the internodes and petioles are secured, describe irregular spires or regular ellipses, exactly like those made by the internodes. The Movements and Habits of Climbing Plants The internode which carries the upper active tendril and which likewise carries one or two younger immature internodes, made three revolutions, following the sun, at an average rate of 1 hr. The Movements and Habits of Climbing Plants During several days the tendrils or internodes, or both, spontaneously revolve with a steady motion. The Movements and Habits of Climbing Plants The internodes do not revolve; nor do those of the hybrid P. floribunda. The Movements and Habits of Climbing Plants Canes slender, dark brown, surface roughened; nodes enlarged, flattened; internodes short; tendrils intermittent, short, bifid. Manual of American Grape-Growing Neither the internodes nor the petioles are irritable when rubbed. The Movements and Habits of Climbing Plants But the movement of each separate internode is so independent of the others, that cutting off an upper one does not affect the revolutions of a lower one. The Movements and Habits of Climbing Plants When the stem is secured, the tendrils are seen to revolve in nearly the same manner and at the same rate as the internodes. The Movements and Habits of Climbing Plants This movement of the leaves would aid that of the internodes in bringing the petioles into contact with surrounding objects. The Movements and Habits of Climbing Plants Canes medium in length, numerous, reddish-brown with thick bloom; nodes enlarged; internodes short; shoots glabrous; tendrils intermittent or continuous, bifid. Manual of American Grape-Growing We know that the internodes, whilst still very young, do not acquire their proper rate of movement; hence the several shoots on the same plant may sometimes be seen revolving at different rates. 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. The Movements and Habits of Climbing Plants In most other respects a tendril acts as if it were one of several revolving internodes, which all move together by successively bending to each point of the compass. The Movements and Habits of Climbing Plants The revolving movement continues as long as the plant continues to grow; but each separate internode, as it becomes old, ceases to move.
