If we go through the evolution of human society, we will come to know that plants have always played important role in human life. Human settlement, quite often, shifted from one place to another in search of natural vegetation. Whether man was hunter, or concentrated on animal husbandry, or even became cultivators, they needed green surrounding for their day-to-day life. The present paper tries to highlight the historicity of botanical environment on the basis of plant remains, from the different archaeological sites of Iran. To ascertain the relationship between human being and plants, in Iran or elsewhere, archaeologists followed various techniques and analyses such as pollen analysis, charred seeds and woods analysis, organic residue analysis as well as ethno- archeology. This paper, particularly on the basis of archaeobotanical analysis, tries to show how the plant and seed remains demonstrate cultural interregional contacts.
