For many years, the author and some of his colleagues have collected and assessed some of the marcrobotanic samples from the archaeological sites in Vietnam. These samples include Canarium, Juglans-like, Quecus/castanopsis, Aleurites and Celtis from Stone Age sites and some other samples of seeds from Metal Age sites. The assessment contributes to the awareness of the ancient environment, economic patterns and other living activities of the ancient inhabitants.
