New delimitation of two series within Alchemilla subsection Calycanthum and new subdivision within Alchemilla series Calycinae (Rosaceae)

The distinctions between Alchemilla ser. Calycinae and A. ser. Elatae are emended, treating the latter group as relict, connected to the Tertiary broadleaved forests of the eastern Mediterranean Basin. Alchemilla ser. Calycinae (in renewed circumscription) is subdivided into seven provisional aggregates according to the specially developed coordinate system (with two axes — a ratio of central zone width to leaf length vs. number of leaf teeth in total). The original key included all the species of the series occurring in the Caucasus and Asia Minor was compiled.
