Summary A collection of Paleogene plants reputed to contain distichous short shoots of Taxodium and Metasequoia (Taxodiaceae) has been studied. The evidence to support this view is weak and it appears that if a genus of the Taxodiaceae is involved, Sequoia is the most likely. A number of other gymnospermous genera, both within and without the Taxodiaceae, could have produced these shoots but there is no clear evidence to decide which one of them. These plants are referred to Elatocladus Halle, a form genus for sterile coniferous and taxad shoots.
