This research was done to recognize different stomata types and to determine its position in comparison with epidermal cells in the genus Tilia. The results showed that the length, width and area of stomata had significant differences in the studied populations, while the density of stomata did not show any significant difference. The maximum and minimum stomata area were related to Loveh (the east of Hyrcanian forest) and Chamestan populations, respectively. Correlation analysis showed positive correlation between longitude and size of stomata, specially stomata area, and also negative correlation between latitude and size of stomata. Discriminate analysis indicated 60 percent correspondence between stomata characters and ecological condition of populations. Four stomata types of stomata including Anisocytic, Parasitic, Anemositic and Anemositic with undulate wall identified for the Genus Tilia in hyrcanian forest. Also, regarding position of stomata in comparison with epidermal cells. Three types of stomata were recognized. Type1, stomata located in lower than epidermal cell, found in high altitude populations (>2000m a.s.l). Type2, stomata located in upper than epidermal cell, found in eastern populations of hyrcanian forest (Loveh populations). Type3, stomata located as level as the epidermal cell, observed in middle altitude populations (including Valikbon, Vaz and Chamestan).
