Phase diagram for 3-symmetry whorled patterning.

Whorled phyllotactic patterns change with spontaneous curvature interaction β and stress tensor coupling γ. When γ increases β decreases in order to maintain the emergence of primordia as whorled patterns. Aberrant patterns (AB) emerge outside of the dash blue lines. Parameter values are η = 0.26, G[u] with a width of R/2, κ = 2 and c = 0.57.
