circumnutate

We may therefore conclude that the leaves of Acanthus circumnutate periodically, falling in the morning and rising in the afternoon and night.

We see from these three cases that stolons or runners circumnutate in a very complex manner.

But the tracing shows that the basal part of the radicle continued to circumnutate irregularly during the whole time.

The cotyledons therefore circumnutate independently of the movement of the hypocotyl.

From The Power of Movement in Plants by Charles Darwin

That an arched hypocotyl or epicotyl, with the two legs fixed in the ground, should be able to circumnutate, seemed to us, until we had read Prof. Wiesner's observations, an inexplicable fact.

Cotyledons.—On two occasions the movements of the cotyledons were traced on a vertical glass, and as the ascending and descending lines did not quite coincide, very narrow ellipses were formed; they therefore circumnutated.

On the third morning they fell very much, and then circumnutated on a small scale round the same spot; by 8.20 P.M. they showed no tendency to rise at night.

The apex after thus sinking down from 9.10 A.M. to noon, moved a little to the left; it then rose up and circumnutated in a nearly vertical plane until 10.35 P.M.

There can therefore be no doubt that this young leaf circumnutated.

From The Power of Movement in Plants by Charles Darwin

It manifestly circumnutated, though only to a small extent.

The circumnutating movement, therefore, of this young leaf was strongly marked.

Morren, however, has observed** in the stamens of Sparmannia and Cereus a "fremissement spontané," which, it may be suspected, is a circumnutating movement.

THE following chapter is devoted to the circumnutating movements of the radicles, hypocotyls, and cotyledons of seedling plants; and, when the cotyledons do not rise above the ground, to the movements of the epicotyl.

Another leaflet was casually observed, and found to be continually circumnutating during the same length of time.

From The Power of Movement in Plants by Charles Darwin

In A we see the complex circumnutating course pursued from 11.30 A.M.
