Abstrakt

The presence of Keteleeria in the Miocene of eastern China is confirmed by the discovery of a cone, winged seeds, and leafy shoots. These are described and compared with other fossil and recent representatives. The best match was with K. rujadana, a K. fortunei-like fossil from the Oligocene of Oregon, U.S.A. The presence of similar, if not identical taxa, on both sides of the Pacific indicates that in the Mid-Tertiary exchange between East Asia and North America via the Beringian land-bridge was still possible. With global cooling in the Tertiary, this thermophilic conifer became scarce. Its present restricted distribution dates from the Quaternary.
