Two notions of conspicuity and the classification of phyllotaxis.

摘要: Invoking cylindrical Bravais lattices, Adler (1974, 1977) proposed a mathematically precise definition for the botanical classification of phyllotaxis. It is based on opposed pairs parastichy families, that are conspicuous and visible. Jean (1988) generalized this concept to non-opposed families. In present paper it shown generalization implies notion conspicuity different from Adler's. This made obvious by redefining key terms two approaches. Both classifications well defined. For Adler's, presenting general proof his conjecture (in sense Adler) families There indications in applications models phyllotaxis (van Iterson model, inhibitor models) their solutions better characterized Jean's classification. The differences between Adler's show up only very rare cases, so practice pattern determination insignificantly touched results. turns out widely used contact method determine phyllotactic patterns gives results according rather than
