Bertrand^ has described structural material offruits allied to Cephalotaxus under the name of Vesquia Tournaisii fromthe Aachenian of Belgium and the present writer has described * similarfruits which are common in the Upper Cretaceous of the SouthernAtlantic Coastal Fig. 12.—Sketch map of the world showing the approximate distribution ofthe existing Taxaceae, horizontal lining = subfamily Taxeae, vertical lining =subfamily Podocarpese. The existing genus Cephalotaxus Sieb. and Zucc, contains fourspecies confined to the Chinese-Japanese region. It was evidently muchmore widespread in former geologic times and to it should possibly bereferred some of the leafy twigs included in the genus Taxites Bron- ?? Heer, Fl. Foss.
