Resumen de New sections in Taraxacum
Sectional taxonomy of Taraxacum in steppe or subsaline habitats in Central Asia is revised based on material collected during expeditions, cultivated or studied in herbarium. Two new sections are described from that area: T. sect. Stenoloba similar to 12 sect. Leucantha (syn.: /1 sect. Sinensia), and/1 sect. Suavia allied to T. sect. Dissecta. The type species of the section Suavia is described as Taraxacumformosissimum KIRSCHNER et ~Tt~PANEK. Widespread mountain dandelions of the Caucasus, intermediate between the sect. Piesis and T. stevenii, are described as T. sect. Confusa. Taraxacum species dominating dry habitats in S Ukraine and Crimea are described as T. sect. Borysthenica. Species belonging to the new sections were found to be polyploid and agamospermous.
