From Hubert Airy   16 July 1872

Summary

Thanks CD for reading his MS [8412] and for his suggestions.

Clarifies his statement on the contraction of the bud-axis: did not mean to imply that this contraction occurred in an individual’s life-time, rather that it was the effect, after the course of ages, of successive favourable modifications.

Believes the true theory of phyllotaxy will give a convincing illustration and proof of the theory of evolution.

From Hubert Airy   20 July 1872

Summary

Discusses the significance of the node. Believes, with CD, that it has no independent importance but is merely the consequence of the presence of a leaf. Does not believe a distinction can be made between whorled and alternate leaf arrangements on the basis of the number of leaves springing from a node. The node, as the starting point of a leaf, is subject to any disarrangement which takes place among the leaves.

From Hubert Airy   8 January 1874

Summary

W. J. Beal’s paper ["Phyllotaxis of cones", Am. Nat. 7 (1873): 449–53] shows incompleteness of HA’s theory, but does not invalidate his basic principles on origin of leaf arrangement or the broad applicability of the theory.

From Hubert Airy   17 March 1873

Summary

Thanks for congratulations on appearance of abstract of HA’s paper [Nature 7 (1873): 343–4].

Explains again his theory of "contraction with twist" by which compact buds and a spiral phyllotaxy have evolved. Explains how the peculiar phyllotaxy of the teasel is explicable by this process of "condensation".

Summary

Thanks for letter, in which CD cited [Anton] Kerner’s alpine observations.
