The changes of position of leaves and of climbing plants, and the sleep of leaves are all brought under this great principle of circumnutation.
I hope that you will not have upset my fundamental notion that various classes of movement result from the modification of a universally present movement of circumnutation.
The present letter is interesting in referring to F.itz Muller's observations on the "revolving nutation," or circumnutation of Alisma macrophylla and Linum usitatissimum, the latter fact having been discovered by F. Muller's daughter Rosa.
This was probably the earliest observation on the circumnutation of a non-climbing plant, and Muller, in a paper dated 1868, and published in
This I proved to be the case; and I was further led to a rather wide generalisation, viz. that the great and important classes of movements, excited by light, the attraction of gravity, etc., are all modified forms of the fundamental movement of circumnutation.
If so, the facts on circumnutation must have been communicated to Darwin some years before their publication in the "Jenaische Zeitschrift.")
