Amborella, the putatively basalmost extant angiosperm, is poorly known in its reproductive structures. This study offers new results. Inflorescences are botryoids or panicles with accessory flowers in the lower bracts. Flowers are small. Floral phyllotaxis is spiral throughout. The flower base forms a shallow cup that tears into irregular lobes when the flower opens and expands so that the inner floral organs are presented on a flat plate. The flowers are functionally unisexual but they have a… Expand
