We analyzed the pollen subfossils from a 323cm sediment profile in the Duck Pond on the western part of Mt. Cising, and identified 19 pollen taxa. Five subfossil pollen taxa, including Acer serrulatum type, Lagerstroemia subcostata type, Trochodendron aralioides type, Alnus formosana type, and Haloragis micrantha type, are identified to species level. Based on the scanning electron microscope images, we describe the morphological characters of every pollen subfossil type and discussed the spatial distributions and ecological meaning of the related plants in Yangmingshan National Park now.
