摘要: Abstract This paper is devoted to clarifying definitively the mathematical relations between parameters involved in Richards's centric representation of spirally arranged primordia plants. The are divergence angle, plastochrone ratio, and phyllotaxis index, together with necessary adjustments on approximately conical surface apex; spirals (the so-called parastichies) logarithmic. We give examples discuss, light recent advances, some trials dealing descriptive theory.
