circumnutation

/ ˌsɜkəmnjuːˈteɪʃən /

noun

C19: from circum- + -nutate, from Latin nūtāre to nod repeatedly, sway

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.
