Pollen and spore keys for Quaternary deposits in the northern Pindos Mountains, Greece

Keys for identification of pollen and spores of extant plants in Grevena´Province, northwestern Greece are presented at the lowest commonly achievable taxonomic rank, based on light microscope observation. As the Province includes a range of vegetation from lowland evergreen oak woods, through semi-deciduous and deciduous oak and mixed deciduous forests at middle elevations, to higher altitude beech and pine woods and alpine meadows, the keys cover most common pollen and spores encountered in Quaternary deposits in upland areas of southeastern Europe. Special attention has been paid to closely identifying pollen and spores of particular interest to the archaeologist. Based on compilations of existing data and new observations, separate special keys are included for Caryophyllaceae, Cyperaceae, Gramineae, Malvaceae, Plantaginaceae, and Rosaceae. A full list of species included in each pollen type is provided.
