eastern Texas. American Journal of Botany 67 (3): 309-320.
Abstract: A new flower and inflorescence-bearing locality has
been discovered in the Oligocene of the Texas Gulf Coast. The
new flora is similar to the Middle Eocene Claiborne Flora of the
southeastern USA, but the quality of preservation is sometimes
better in the Oligocene fossils. One component of the new flora,
a mimosoid legume inflorescence, appears identical with
Eomimosoidea plumosa, first reported from the Claiborne
Formation of western Tennessee. Investigations of these younger
specimens indicate that the taxon had changed little during the
Middle Eocene -Oligocene interval, and the better quality of
preservation of the Texas specimens has provided further
insights into the structure of the fossils. Comparisons of the
fine structural details of the pollen o
