The initiation, ontogeny, and subsequent anthesis of the secondary capitulum is homologous to that of a synflorescence or collection of primary capitula (Classen-Bockhoff, 1992; Harris, 1994; Kunze, 1969; Rauh & Reznik, 1953); that is, the individual or primary capitula are initiated in an acropetal sequence and develop acropetally, but they then undergo anthesis basipetally.
The syncephalium subunit primordia (SSPs) are initiated acropetally in orderly parastichies on the capitulum.
