DISTRIBUTION AND ECOLOGY. — R. pseudohaussknechtii is an endemic species native to Eastern Anatolia, identified from the Munzur Mountains and the nearby Tayran Mountains. The distribution area of the species is limited and it grows on calcareous rocks at elevations between 1500 and 2800 meters. The distribution area and population status of R. pseudohaussknechtii could not be evaluated due to insufficient data. While R. haussknechtii s.str. is distributed in Southeastern Anatolia, R. pseudohaussknechtii is distributed in Eastern Anatolia. Some morphological characteristics of both species are shown in detail in Table 2. View TABLE
