Initial attempts to name one specimen using the Flora of Turkey (Davis, 1965; Davis et al., 1988; Güner et al., 2000) were not successful. Eventually, using the family account in the Flora of Iraq (Townsend, 1980), Flora Iranica (Rechinger, 1968), Flora URSS (Kamarov, 1970) and Flora Palaestina (Zohary, 1966) the specimens were identified as Leptaleum filifolium (Willd.) DC. It was a new record for Turkey. The record is not surprising since the species also grows in nearby Iraq, Iran, and Syria. Leptaleum DC. is monotypic and exists mainly in the Irano-Turanian region. The name derives from the Greek leptaleos (slender), referring to the filiform leaves (Townsend, 1980). The species has a wide range of distribution in SW Asia. So far L. filifolium is known from Iran, Iraq, Syria, Lebanon, Arabia, and Egypt (Figure 1); it is also found in the Caucasus, W .
