Airy had suggested that the form of the bud was an important element in phyllotaxy (see letter from Hubert Airy, 9 December 1871 and n. 3). In his reply, CD had cited Carl Wilhelm von Nägeli’s observation that the position of leaves in the bud was not fixed (see letter to Hubert Airy, 10 [December] 1871 and n. 6).
Airy refers to Chauncey Wright. See letter to Hubert Airy, 10 [December] 1871.


Thanks for letter and reference to Nägeli’s observations on leaf arrangement in the bud.
