A review of some Tertiary endocarps of Celtis Ulmaceae



A review of some Tertiary endocarps of Celtis Ulmaceae



The Southwestern Naturalist 11(2): 211-216



Taxonomy of the fossil species of Celtis is reviewed and morphologic features of the endocarp (fruit stone) are described. Well preserved fossil endocarps are abundant in Tertiary deposits in the High Plains region of central United States. C. hatcheri (Oligocene, near Scenic, N. Dak.) and C. willistoni (Pliocene, Ogallala Formation, Kansas, and Miocene-Pliocene, widespread) are shown to be distinct species. Comparisons are made with the living hackberry, C. reticulata, which is common in the same region.
