Abstract
Daisies, and composite flowers, exhibit an ordered arrangement of florets (phyllotaxis) generated by a simple algorithm. Their structure has self-similarity (inflation), golden mean, Fibonacci numbers, and quasicrystalline grain boundaries, for elementary crystallographic (homogeneity) and biological reasons. Grain boundaries are also 2π-disclinationsThis publication has 2 references indexed in Scilit:
