(Figs. 37, 28.) Passing over these for the present, we find that the flower- ing plants are repre- sented in the Brian forests by at least two types of Gym- uosperms, that of Taxinew or yews, and an extinct family, that of the Cordaites (Figs. 30, 31). The yew-trees are closely allied to the pines and spruces, and are often included with them in the family of Coniferm. They differ, however, in the habit of producing berries or drupe-like fruits instead of cones, and there is some reason to believe that this was the habit of the Brian trees of this group, though their wood in some in- stances resembles rather that of the Araucarja, or Nor-.
