They resembled more or less the tropical Araucaria, the broad-leaved Chinese Salisburia (Ginko), or the curious two-leaved African Wehuitsehia. A very interesting genus is that of Cordaites. It had a straight trunk, sometimes sixty to seventy feet

Such a form and structure is entirely unlike anything known among ferns or Cycadofilicales, and certainly approximates that of the leaves of Cordaites. Scott (8) says that such a leaf organization is comparable to a single leaflet of such a cycad as Bowenia. THE ROOT Amyelon radicans is a root of the Coal-measures known to belong to Cordaites, and often preserved in remarkable detail (fig.
