The author has been working on the project Flora of Iran (Asteraceae-Lactuceae) since 2000. In this period all specimens of the tribe in Iranian herbaria were revised. The present paper is including some results of the project.
Scorzonera luristanica Rech .f. var. lanata Safavi. is described from N.W. of Iran as a new variety to the science. The differences between the new variety and the type variety are also discussed. All of the Iranian Scolymus L. specimens (four specimens in the Central Herbarium of Iran, Research Institute of Forests and Rangeland TARI"and one specimen in IRAN Herbarium, Research Institute of Plant Pests and Diseases) were revised and determined. According to the descriptions of Scolymus L. species in Flora Iranica all of the revised specimens are Scolymus maculatus L., although the specimens were previously named as Scolymus hispanicus L.
Among the specimens of Iran Herbarium one specimen was seen from Khuzestan: Shush, no. 34009-E, the specimen has determined as Scolymus hispanicus L. by Rechinger (1977), this specimen has renamed to Scolymus maculatus L. by the present author. So from two species of Scolymus L. in Flora Iranica area only Scolymus maculatus L. occur in Iran (West & Southwest).
