Satureja rechingeri, an endemic species from Iran, is distributed in narrow habitats in Ilam andKhuzestan provinces. This study was conducted in 2013 and some morphological characteristics, oilcontent, rosmarinic acid content and ecological features of different populations of S. rechingeriwere studied. Identified habitats of S. rechingeri are located in sub-tropical areas of Ilam andkhuzistan provinces, within 32-33◦ longitude and 46-49◦ latitude and the plant mainly grows oncalcareous rocks in the northern and southern slopes. The highest coefficient of variation among thetraits of S. rechingeri was obtained for leaf surface area (43.01%) and the lowest (9.25%) wasobtained for the diameter of the calyx. The coefficient of variation for essential oil yield was33.71%. The lowest (2.1%) and the highest (3.51%) average essential oil yields were observed inKaver and Lives populations, respectively. Minimum (0.93%) and maximum (6.2%) essential oilyields were observed among the individuals of the Lives and Kaver populations, respectively.Highest (54.49%) coefficient of variation for rosmarinic acid content was observed in Bone Adabpopulation. Amount of rosmarinic acid of methanolic extract of under study populations showedhigh variability and varied from 0.54 to 7.29% among individuals, while the average rosmarinicacid in populations varied from 1.62 percent (Kaver population) to 4.14 percent (Zarrin Abadpopulation). Diversity of S. richingeri within populations was higher than among them showinglimited segregating of populations.
