In the last decade important progress has been made regarding pattern
recognition and generation of the phenomenon of phyllotaxis. Phyllotax

through evolutionary biology and general comparative morphology. This
review summarizes the contributions in the area, redefines the challen
ge, and proposes an adequate framework for the study of the phenomenon
