Transitive Inflorescence Types in Spiraea (Rosaceae-Spiraeoideae) Undermine the Fundamental Classification Concept of the Genus

Popis výsledku v původním jazyce

The main aim of this study is to show that the concept of simple or branched pedicels that has long been used as the primary trait for species classification in the genus Spiraea is improper, at least in some species that form both types of pedicels, i.e. simple and compound inflorescences (corymbs). This finding undermines the basic classification of the genus, dividing species with simple or compound inflorescences as members of sections Chamaedryon and Calospira, respectively. Transitions between simple and compound inflorescence types exist within individuals of several Spiraea species. The occurrence of both morphological states in S. arcuata has led to its heterogeneous interpretation and seeming dual systematic position. Spiraea schneideriana and S. myrtilloides represent two states of what is evidently one species: the latter, with typically simple corymbs, is accepted as a variety of the former, with more or less compound corymbs. The neglected occurrence of occasionally bran
