How to use circumnutation in a sentence
It is sufficient for my purpose to point out that Darwin's explanation of circumnutation is not universally accepted.
Personally I believe that circumnutation is automatic—is primarily due to internal stimuli.
Under these conditions circumnutation becomes irregular or ceases altogether.
The bare fact that circumnutation is a general property of plants (other than climbing species) is not generally rejected.
