"The leaf rosettes of the carnivorous Pinguicula moranensis follow a spiral phyllotaxis approaching a Fibonacci pattern while the stalked flowers arise from extra-axillary sites between the leaves…The leaves of consecutive articles of such sympodially constructed rosettes are arranged along a spiral Fibonacci pattern (with divergence angles around 137°)…Sympodial construction of flowering shoots and leaf rosettes is also known from Aloe, Gunnera and Philodendron." (Grob et al. 2007:857)
