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. It is possible that the stems of some plants by spontaneously turning on their own axes, at the proper rate and in the proper direction, might avoid becoming twisted; but I have seen no such case.

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. In the genus Mikania, there are leaf-climbing and twining species. The leaf-climbing species of Clematis are very closely allied to the tendril-bearing Naravelia.

He honored certain plants with special regard, and, over all, the pond lily, then the gentian, and the Mikania scandens, and "life-everlasting," and a bass-tree which he visited every year when it bloomed, in the middle of July. He thought the scent a more oracular inquisition than the sight more oracular and trustworthy. The scent, of course, reveals what it concealed from the other senses.

H. M. July 7, 1st circle was made in 6 18 8, 2nd 6 53 9, 3rd 6 30 As long as a plant remains under the same conditions, the rate is often remarkably uniform, as with the Hop, Mikania, Phaseolus, &c. The Scyphanthus made one revolution in 1 hr. 17 m., and this is the quickest rate observed by me; but we shall hereafter see a tendril-bearing Passiflora revolving more rapidly.

Don Pablo recognised them as the leaves of a plant of the genus Mikania, and known popularly as the "vejuco de guaco." Guapo knew nothing of the scientific designation of the plant, but he had long ago been taught the valuable properties of its leaves as an antidote against the bite of the most poisonous snakes. What, then, did Guapo with the leaves of the vejuco?

I have seen no instance of two species of the same genus twining in opposite directions, and such cases must be rare; but Fritz Muller states that although Mikania scandens twines, as I have described, from left to right, another species in South Brazil twines in an opposite direction. One of these four plants made seven spiral turns from right to left, and five turns from left to right.

Into each of these incisions, even while the blood was flowing from them, he dropped the juice of the Mikania, and rubbed it in with fresh leaves of the plant itself; and then, with some tufts of the soft floss of the silk-cotton tree he covered the incisions, so as to stop the bleeding.
