Floral shoot anatomy in Trollius asiaticus and seedling morphology in T. altaicus, T. apertus, T. asiaticus, T. europaeus, T. ledebourii and T sajanensis were studied in early ontogeny stages. In four species, there occurs syncotyly, its distribution among the species of the genus being probably a valuable characteristic to understand the genus phylogeny. In T. asiaticus, vascular bundles are closed, stems are unable to any secondary increase in thicknes; sclerenchyma is not located radially but forms massive strands externally to the vascular bundles.
