I hide the tendril under the leaf against the sun, which is the only enemy we have to consider.” “Ah! but the fork does not raise so much dust as the plough and the heavy cattle which draw it,” returned Agellius; “and the said dust does more for the protection of the tendril than the shade of the leaf.” “But those huge beasts,” retorted the slave, “turn up great ridges, and destroy the yard.”
And a peculiarity of their intercourse was, that, let her depart in what freak or perversity she pleased, she seemed always to have a certainty of finding him in the same mood in which she had left him, as some bright wayward vine of Southern forests puts out a tendril to this or that enticing point, yet, winding back, will find its first support unchanged. Shut out, as Mr.
A large majority of its so-called tendrils still bear leaflets, though excessively reduced in size; but some few of them may properly be designated as tendrils, for they are completely destitute of laminae or blades. Consequently, we here behold a plant in an actual state of transition from a leaf-climber to a tendril- bearer.
On the last occasion, however, the movement was very slight, and soon afterwards permanent spiral contraction commenced. No trials were made during the night, so that the tendril would perhaps have answered a greater number of times to the stimulus; though, on the other hand, from having no rest it might have become exhausted from so many quickly repeated efforts.
A tendril, as soon as it is ready to act, stands, together with the supporting petiole, vertically upwards. The leaflets borne by the petiole are at this time quite small, and the extremity of the growing stem is bent to one side so as to be out of the way of the revolving tendril, which sweeps large circles directly over head.
Old trees renewed their youth in the slight, tenacious grasp of many a tremulous tendril, and, leaping lightly above their topmost heights, vine laughed to vine, swaying dreamily in the summer air; and not a vine nor brook nor hill nor forest but sent up a sweet-smelling incense to its Maker.
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. For a few days after the attachment of the discs, the tendril remains weak and brittle, but it rapidly increases in thickness and acquires great strength.
But it must be remembered in looking for this that it is the same tendril which should be examined, and not two different ones. It will then be seen that the tendril, after forming a spiral one way, lengthens out like a tiny green wax taper, and afterwards turns the other.
Buds can be forced in the same way to grow from the axils of the lower scales, and even from those of the cotyledons, and the lesson may be again impressed that organs are capable of undergoing great modifications. The teacher may use his own judgment as to whether he will tell them that the tendril is a modified leaflet. Grain of Indian Corn. 2.
As the pairs of tendrils grow old, one tendril diverges more and more from the other, and both slowly bend backwards and downwards, so that after a time they project on the opposite side of the stem to that from which they arise. They then still retain their sensitiveness, and can clasp a support placed BEHIND the stem. Owing to this power, the plant is able to ascend a thin upright stick.
