| Such are the majority of the scales of the cone and represent more or less indefinite conditions of phyllotaxis. |
| The Fibonacci numbers are also exemplified by the botanical phenomenon known as phyllotaxis. |
| The former condition represents a lower, the latter condition represents a higher, order of phyllotaxis. |
| The angle of divergence may alter either abruptly or gradually, and the phyllotaxis thus becomes very complicated. |
| Spiral phyllotaxis patterns have only parastichies, whereas whorled patterns have both orthostichies and parastichies. |
| Such arrangements, called phyllotaxis, have been studied by scientists for decades. |
