Taxodiese are represented by Sequoia in the Cretaceous and Eocene shale. Pence australis of Van Diemen's Land and P. Pritchardi of Ireland are Tertiary plants. Isoetes is mentioned by Schimper as a Tertiary genus. Although the vegetation throughout the whole of the Tertiary period presents pretty uniform characters, still there are notable differences in the generic and specific forms, and in the predominance of certain orders at dif- ferent epochs. In the Eocene formation, the fossil fruits of the Isle of Sheppey increase the number of Phanerogamous plants, only a small proportion of which have as yet been described. This is an exceptional locality, and is perhaps an example of the effects of cur- rents in conveying exotic plants from remote climates. The Eocene epoch in general is characterised by the predomi- nance of AlgsB and marine Naiadacese, such as Caulinites and Zosterites; Fig. 940. Section of a recent Palm stem, to show its stmctnre.
