Among the genera also enumerated by Colonel Gutbier are the fruit called
Cardiocarpon (see Figure 427), Asterophyllites, and Annularia, so characteristic
of the Carboniferous period; also Lepidodendron, which is common to the Permian
of Saxony, Thuringia, and Russia, although not abundant. Neoggerathia (see
Figure 428), the leaves of which have parallel veins without a midrib, and to
which various generic synonyms, such as Cordaites, Flabellaria, and Poacites,
have been given, is another link between the Permian and Carboniferous
vegetation. Coniferae, of the Araucarian division, also occur; but these are
likewise met with both in older and newer rocks. The plants called Sigillaria
and Stigmaria, so marked a feature in the Carboniferous period, are as yet
wanting in the true Permian.
Among the remarkable fossils of the Rothliegendes, or lowest part of the Permian
in Saxony and Bohemia, are the silicified trunks of tree-ferns called
generically Psaronius.
