Abstract
Trifolium elazizense, a new species of Trifolium sect. Trifolium from East Anatolia in Turkey is described. It grows in subalpine regions with steep slopes and shallow soil at high altitudes. The new species is morphologically close to T. longidentatum and T. kurdistanicum, and can be considered a member of the new subsect. Stipulia. Trifolium elazizense is characterized by hairy stipules, the throat of calyx closed by callus hairs, inflorescences without bracts, obviously unequal calyx teeth, longest tooth 3-nerved, others 1–3 nerved.
