Secondly and thirdly, Bignonia unguis with its close allies, and Cardiospermum; but their tendrils are so short that their contraction could hardly occur, and would be quite superfluous. Fourthly, Smilax aspera offers a more marked exception, as its tendrils are moderately long.
Very soon afterwards it disarticulates itself from the petiole, and drops off like a leaf in autumn. I have seen this process of disarticulation in no other tendrils, for these, when they fail to catch an object, merely wither away. Bignonia venusta. The tendrils differ considerably from those of the previous species.
He saw the distant slaves at their toil; he saw afar their villages of huts gleaming out in long rows on many a plantation, distant from the stately mansions and pleasure-grounds of the master; and as the moving picture passed on, his poor foolish heart would be turning backward to the Kentucky farm, with its old shadowy beeches, to the master's house, with its wide, cool halls, and near by the little cabin, overgrown with the multiflora and bignonia.
From the facts now given, we may infer that though the tendrils of this Bignonia can occasionally adhere to smooth cylindrical sticks and often to rugged bark, yet that they are specially adapted to climb trees clothed with lichens, mosses, or other such productions; and I hear from Professor Asa Gray that the Polypodium incanum abounds on the forest-trees in the districts of North America where this species of Bignonia grows.
Another pigment, much more valuable, is extracted from a plant of the family of the bignoniae, which M. Bonpland has made known by the name of Bignonia chica. It climbs up and clings to the tallest trees by the aid of tendrils. Its bilabiate flowers are an inch long, of a fine violet colour, and disposed by twos or threes. The bipinnate leaves become reddish in drying.
The tendril-bearing Bignonia Tweedyana emits roots, which curve half round and adhere to thin sticks. I have not closely observed many root-climbers, but can give one curious fact.
In young plants of Bignonia the lower leaves often remain quite unchanged, whilst the upper ones have their terminal leaflets converted into perfect tendrils; in Eccremocarpus I have seen a single lateral branch of a tendril replaced by a perfect leaflet; in Vicia sativa, on the other hand, leaflets are sometimes replaced by tendril-branches; and many other such cases could be given.
The movement begins whilst the tendril is young, and is at first slow. The mature tendrils of Bignonia littoralis move much slower than the internodes. In most Bignonias, Eccremocarpus Mutisia, and the Fumariaceae, the internodes, petioles and tendrils all move harmoniously together.
The monotonous hum of the children's voices seemed thin and strange and far, far off, jarring the sweet bouquet babble; and still as the hours passed, and the winter day waned, the flower Fugue swelled on and on, through the cold and dreary chambers of her heart; now rising stormy and passionate, like a battle-blast, from the deep orange trumpet of a bignonia; and now whispering and sobbing and pleading, from the pearly white lips of hallowed oxalis.
This species closely resembles the last in the structure and movements of its tendrils. I also casually examined a fine growing plant of the allied B. Lindleyi, and this apparently behaved in all respects in the same manner. Bignonia capreolata. We now come to a species having tendrils of a different type; but first for the internodes.
