Abstract:

Cousinia elata has been known from only two collections, and its relationship to the major subgroups of the genus has been entirely unclear. It is shown that C. meshhedensis must be included in C. elata, that C. elata is actually widely distributed in NNE and NE Iran, and, based on chromosome number, flower and pollen morphology, that it is a member of Cousinia s.str. (C. subg. Cousinia). Within Cousinia s.str., C. elata is most closely related to species traditionally classified as C. sect. Platyacanthae, based on a Bayesian ITS sequence analysis. The name C. elata and its synonyms C. meshhedensis and C. strictissima are lectotypified and an amended description of the species and a map of its distribution are provided.

  • Willdenowia is a peer-reviewed botanical journal with an international authorship, publishing original research papers in English from the entire fields of plant, algal and fungal taxonomy and systematics, also covering related fields. Its precursor was founded in 1895 as Notizblatt des Königlichen Botanischen Gartens und Museums zu Berlin and 1954 continued with its present title commemorating Carl Ludwig Willdenow, 1765-1812, director of the Botanic Garden, first professor of botany in Berlin and author of the fourth edition of Linne's Species Plantarum. Willdenowia appears in two issues per year in a print edition and an open access online edition.
