Phyllotaxis varies along the synflorescence (main shoot and branches); the disposition of the leaves in the vegetative zone is tristichous (phyllotaxis 1/3), whereas in the inflorescence branch zone the bracts, and their branches, have a spiral arrangement.

The transition from the tristichous disposition, being characteristic of the leaves of the vegetative region, to the spiral arrangement in the inflorescence is a relevant feature that should be noted (Guarise & Vegetti, 2008).
