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".

From Hubert Airy 26 [September–November 1873]
Summary
The Royal Society referees have rejected HA’s phyllotaxy paper, and it will not be printed in Philosophical Transactions. HA is not sorry for he has found new facts which limit the applicability of his views. Now believes that the original leaf arrangement was not necessarily always two-ranked but rather that existing arrangements have developed from a variety of forms with differing numbers of leaf-ranks.
