What is "stems"

Usage examples of "stems".

That the stolons are thus aided in passing over obstacles and in winding between the stems of the surrounding plants, the observations above given render almost certain.

From the particulars above given, and remembering in the case of twining plants and of tendrils, how difficult it is not to mistake their bending to all points of the compass for true torsion, we are led to believe that the stems of this Ceratophyllum circumnutate, probably in the shape of narrow ellipses, each completed in about 26 h.

Thus, the great sweeps made by the stems of twining plants, and by the tendrils of other climbers, result from a mere increase in the amplitude of the ordinary movement of circumnutation.

Some are bright-colored, others are pure white, and the stems of one species look as if covered with lace work.

One may sometimes see among the dead leaves in the woods, minute slender bodies with thread-like stems, springing up from the ground, 2 to 3 inches high, of a white color and cylindrical in shape.

They look like slender stems from which the blossoms have been plucked.

Other verbal stems already prefix the stem-vowel as a kind of intensification, e.

Even the stems of seedlings before they have broken through the ground, as well as their buried radicles, circumnutate, as far as the pressure of the surrounding earth permits.

WE have seen in the first chapter that the stems of all seedlings, whether hypocotyls or epicotyls, as well as the cotyledons and the radicles, are continually circumnutating--that is they grow first on one side and then on another, such growth being probably preceded by increased turgescence of the cells.

Observations of this kind are tedious, and it appeared to us that it would be sufficient to observe the stems in about a score of genera, belonging to widely distinct families and inhabitants of various countries.

When we treat of the sleep and other movements of plants, many other cases of circumnutating stems will be incidentally given.

In looking at the diagrams, we should remember that the stems were always growing, so that in each case the circumnutating apex as it rose will have described a spire of some kind.

The stems, for instance, of Iberis and Azalea described only a single large ellipse in 24 h.

Close in front of the tips of the prostrate stolons, a crowd of very thin sticks and the dried haulms of grasses were driven into the sand, to represent the crowded stems of surrounding plants in a state of nature.

For instance, all the young leaves near the summits of several stems stood almost horizontally at 8 A.
