Telekia Baumg.
Telekia is a small genus of one or two species, native from Central-Europe to the Caucasus. Both are cultivated as ornamentals (Knees 2000; Jäger & al. 2008) but only one, Telekia speciosa, is more or less widespread in cultivation. According to recent molecular phylogenetic studies Telekia is closely related to Carpesium and some resiniferous species of Inula, including Inula helenium (Englund & al. 2009). These species are informally accommodated in “the Inula complex”. Pending additional studies both genera are here accepted in their traditional sense.
