illustrated as a new species endemic to Turkey. It is morphologically similar to S. semicana
DC., but differs by its rootstock, deeply undulating basal leaves and glabrous achenes.
Additionally, the size and micro‐morphological properties of achenes and some anatomical
traits of the leaf and stem are helpful in distinguishing these closely related taxa. A
phylogenetic analysis based on nrDNA ITS sequence data showed that S. semicana is the …
