• Resumen

  • Psephellus erzincani and P. recepii from the province of Erzincan in eastern Turkey are described as species new to science and illustrated. Both can be assigned to P. sect. Psephelloidei although the former species differs by the yellowish colour of the flowers and rather inconspicuous marginal flowers. Both are endemic to small areas and must be classified in the IUCN categories Endangered (EN) and Critically Endangered (CR), respectively.
