The complete range of various phyllotaxes exemplified in aquatic plants provide an opportunity to characterize the fundamental geometrical relationships operating in leaf patterning. A new ...

Mathematics is everywhere in nature, and this is illustrated by the spiral patterns in plants such as pine cones, sunflowers or the arrangement of leaves around a stem. Most plants produce a new bud ...

The generation of leaf pattern (phyllotaxis) has long been a topic of interest and debate among plant biologists and mathematicians, as observed by Amar Klar in his Concepts essay 1. As Klar points ...

Researchers at the University of Tokyo used the Expanded Douady and Couder 2 equation to model how leaves are arranged on plant stems. In the new equation, each leaf more intensely inhibits the ...

Already Leonardo da Vinci realized that organs on stems are far away from being randomly distributed, and one doesn’t need to be a scientist to recognize such elaborate systems. The basic phyllotactic ...

According to Charles Darwin, attempts to explain the mathematical patterns of phyllotaxis — the arrangements of leaves or florets on a plant stem — could “drive the sanest man mad”. That hasn't served ...
