“…Well preserved cones and leaves are also recognized from the Miocene of Idaho, USA (Kvaček & Rember, 2000). The genus was confirmed in the Pliocene of Japan based on pollen investigated both by light and scanning electron microscopy (Saito et al, 2001).…”

We review the fossil history of seed plant genera that are now endemic to eastern Asia. Although the majority of eastern Asian endemic genera have no known fossil record at all, 54 genera, or about 9%, are reliably known from the fossil record. Most of these are woody (with two exceptions), and most are today either broadly East Asian, or more specifically confined to Sino-Japanese subcategory rather than being endemic to the SinoHimalayan area. Of the "eastern Asian endemic" genera so far known from the fossil record, the majority formerly occurred in Europe and/or North America, indicating that eastern Asia served as a late Tertiary or Quaternary refugium for taxa. Hence, many of these genera may have originated in other parts of the Northern Hemisphere and expanded their ranges across continents and former sea barriers when tectonic and climatic conditions allowed, leading to their arrival in eastern Asia. Although clear evidence for paleoendemism is provided by the gymnosperms Amentotaxus, Cathaya, Cephalotaxus, Cunninghamia, Cryptomeria, Glyptostrobus, Ginkgo, Keteleeria, Metasequoia, Nothotsuga, Pseudolarix, Sciadopitys, and Taiwania, and the angiosperms Cercidiphyllum, Choerospondias, Corylopsis, Craigia, Cyclocarya, Davidia, Dipelta, Decaisnea, Diplopanax, Dipteronia, Emmenopterys, Eucommia, Euscaphis, Hemiptelea, Hovenia, Koelreuteria, Paulownia, Phellodendron, Platycarya, Pteroceltis, Rehderodendron, Sargentodoxa, Schizophragma, Sinomenium, Tapiscia, Tetracentron, Toricellia, Trapella, and Trochodendron, we cannot rule out the possibility that neoendemism plays an important role especially for herbaceous taxa in the present-day flora of Asia, particularly in the Sino-Himalayan region. In addition to reviewing paleobotanical occurrences from the literature, we document newly recognized fossil occurrences that expand the geographic and stratigraphic ranges previously known for Dipelta, Pteroceltis, and Toricellia.

The results of the morpho‐anatomical investigations show that seed‐ and pollen‐cones of Cathaya represent the typical bauplan for Pinaceae. Several features were found that suggest a closer relationship of Cathaya to Picea and Pinus on the one hand and also to Larix and Pseudotsuga on the other hand. However, the large pollen‐cones of Cathaya resemble in length and number of microsporangiophores those of Cedrus. Cathaya shows also features that are unique among recent Pinaceae like a sylleptic flush of shoots and seed‐cones. Also the absence of bud scales surrounding the seed‐cone and the special microstructure of the pollen grain surface are unique. These features suggest a rather isolate position for Cathaya among recent Pinaceae. Some anomalous microsporangiophores showing three instead of the typical two sporangia lead to the idea that the hyposporangiate microsporangiophores in Pinaceae might be structures derived from a former perisporangiate type as shown for Taxaceae.
