The Story of Evolution Sometimes it twisted spirally, and at other times slanted down nearly to the horizontal direction. The First Men in the Moon Sixthly, and lastly, tendrils, soon after clasping a support, but not after a mere temporary curvature, contract spirally. The Movements and Habits of Climbing Plants The shoots do not twine spirally, but climb excellently by the aid of their young and sensitive petioles. The Movements and Habits of Climbing Plants If they have not come into contact with any object, they ultimately contract spirally, after ceasing to revolve; but in this case the movement is useless, and occurs only after a considerable lapse of time. The Movements and Habits of Climbing Plants The tendrils of Dicentra, whilst the plant is young, are short and after attachment only become slightly flexuous; in older plants they are longer and then they contract spirally. The Movements and Habits of Climbing Plants On the other hand, the tendrils of all tendril-bearing plants, contract spirally after they have caught an object with the following exceptions. The Movements and Habits of Climbing Plants A tendril does not long retain its revolving power; and as soon as this is lost, it bends downwards and contracts spirally. The Movements and Habits of Climbing Plants The stem of this species can twine round an upright stick, and is aided in its ascent by the tendrils seizing the stick alternately some way above and then contracting spirally. The Movements and Habits of Climbing Plants An attached tendril, on the other hand, contracts spirally, and thus becomes highly elastic, so that when the main foot-stalk is pulled the strain is distributed equally between all the attached discs. The Movements and Habits of Climbing Plants Very few tendril-bearing plants can spirally twine up an upright stick. The Movements and Habits of Climbing Plants So again the whole outer surface of a spirally wound tendril becomes wrinkled if it be pulled straight. The Movements and Habits of Climbing Plants In this plant I once observed a main branch after it had caught a stick become spirally flexuous in 7 hrs., and spirally contracted in 18 hrs. 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 If the tendril seizes nothing, it does not contract spirally, but soon withers away and drops off. The Movements and Habits of Climbing Plants A tendril which has not become attached to any body, does not contract spirally; and in course of a week or two shrinks into the finest thread, withers and drops off. The Movements and Habits of Climbing Plants Nevertheless the plant readily ascends a thin upright stick by seizing a point above with its two opposite tendrils, which then contract spirally. The Movements and Habits of Climbing Plants But in the great majority of cases, tendrils which have never come in contact with any object, after a time contract spirally. The Movements and Habits of Climbing Plants All the authors, except Palm and Mohl, who have discussed the spiral twining of plants, maintain that such plants have a natural tendency to grow spirally. The Movements and Habits of Climbing Plants They likewise often become, after a time, in some degree spirally contracted. The Movements and Habits of Climbing Plants The stem twined spirally round a support in the same irregular manner as that of the last species. The Movements and Habits of Climbing Plants Tropaeolum pentaphyllum.—This species has not the power of spirally twining, which seems due, not so much to a want of flexibility in the stem, as to continual interference from the clasping petioles. The Movements and Habits of Climbing Plants Some few can ascend by spirally twining round a support. The Movements and Habits of Climbing Plants After a tendril has clasped a stick, it contracts spirally; if it remains unattached it hangs straight downwards. The Movements and Habits of Climbing Plants These petioles and filaments also show some tendency to contract spirally. The Movements and Habits of Climbing Plants After their development the tendrils contract spirally, and become woody and very strong. The Movements and Habits of Climbing Plants Ultimately the lateral branches contract spirally, but not the middle or main stem. The Movements and Habits of Climbing Plants If it seizes an object, all the branches contract spirally. The Movements and Habits of Climbing Plants First, those which twine spirally round a support, and are not aided by any other movement. The Movements and Habits of Climbing Plants If a tendril catches nothing, after a considerable interval of time the tips of the branches curl a little inwards; but if it clasps some object, the whole contracts spirally. The Movements and Habits of Climbing Plants The shoots sometimes make a whole or a half spire round a vertical stick, they then run straight up for a space, and afterwards turn spirally in an opposite direction. The Movements and Habits of Climbing Plants The tendrils do not contract spirally in any case. The Movements and Habits of Climbing Plants Full-sized tendrils, on the other hand, contract spirally, with the exception of the thick basal portion. 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 But if we hold at the same time a stick in our left hand, in such a position that the strings become spirally turned round it, they will inevitably become twisted. The Movements and Habits of Climbing Plants When a shoot stands near an upright stick, it twines regularly and spirally round it. The Movements and Habits of Climbing Plants The tendrils contract spirally a short time after catching any object; those which catch nothing merely bend slowly downwards. The Movements and Habits of Climbing Plants Young tendrils which have caught a support and are spirally contracted, may constantly be seen on the same stem with the much older unattached and uncontracted tendrils. The Movements and Habits of Climbing Plants As soon as an old tendril bends downwards, it loses all power of movement, and contracts spirally into an entangled mass.
