Phyllotaxis, Darwin and Falconer on.
"More Letters of Charles Darwin Volume II" by Charles Darwin
The subject of leaf-arrangement should be passed over until phyllotaxy is taken up.
"Outlines of Lessons in Botany, Part I; From Seed to Leaf" by Jane H. Newell
Thus, the leaves in assuming a new phyllotaxy, take one quite analogous to the normal one.
"Vegetable Teratology" by Maxwell T. Masters
This is the leaf-arrangement or phyllotaxy of the apple-tree, expressed by the fraction 2/5.
"The Apple-Tree" by L. H. Bailey
Four quadrangular scales in mutual contact represent the condition of definite phyllotaxis.

One of Turing’s main achievements was to come up with mathematical descriptions — differential equations — governing such phenomena as Fibonacci phyllotaxis: the surprising showing of Fibonacci progressions in such things as the criss-crossing spirals of a sunﬂower head.
Definability in the Real Universe
In his formulation of the Hypothesis of Geometrical Phyllotaxis he expressed simple rules adequate for the appearance of Fibonacci pattern.
Definability in the Real Universe
The basic principle of phyllotaxis has been formulated as early as 1868 by Hofmeister and states that each new structure (leaf, ﬂoret, seed,etc.) appears ”opposite” to the previous one - or ones.
