Abstract: 
Papaveraceae are known for their often showy flowers and diverse morphologies. Pteridophyllum racemosum (Siebold & Zucc.) is the only member in the Pteridophylloideae within the Papaveraceae, and its phylogenetic position has long been controversial, and a comprehensive analysis of its floral morphology was lacking. Our study focuses on the floral morphogenesis of P. racemosum. Histological sections complemented with scanning electron microscopy allowed a detailed characterization of P. racemosum floral development including description of the vegetative morphology, showing (1) the fine structure of the unusual pinnate leaves; (2) the well-defined floral structure and disymmetry; (3) a series of landmarks in floral development stages, with emphasis on the development of the gynoecium. Interestingly, the P. racemosum floral architecture is similar to that of the proposed ancestral Papaveraceae flower supporting the phylogenetic placement of P. racemosum as an early branching lineage within the Papaveraceae. Our comprehensive overview adds to the colorful library of floral diversity in Papaveraceae, providing a solid base for comparative analyses.
