Column 3. Sub-conglomerate; Mauch Chunk No. XI.?*
* The
plants are not separated by their local habitats, but only by the names
of the States in which their habitats lie; as they are not
sufficiently known from local sections. They may define geological
groups like those in the following columns. The relation of the Penn'a
XI to the sub-conglomerate of the other States is not definite.
