Abstract:

Phyllotaxis, the arrangements of phylla (leaves, flowers, seeds, bracts) on plants has mystified and intrigued natural scientists for millenia. Indeed it was over four hundred years ago that Kepler first noted that phylla often lay on families of spirals and that the numbers in these families were enumerated by Fibonacci sequences. It is only recently, amazing when you think about all the great names who worked on it, that real progress has been made. I will describe for you what the progress has been and show you some fascinating new results which suggest that nature may use pattern forming systems to pursue and achieve optimal strategies.
