lepidodendraceæ

from The Century Dictionary.

• A family of Paleozoic fossil plants of the order Lycopodiales, typified by the genus Lepidodendron (which see). Several other genera have been described, as Knorria, Halonia, Ulodendron, etc., which, however, are now believed to represent so many parts or aspects of Lepidodendron; but Lepidophloios seems to be a distinct genus. The roots belong to Stigmaria, but do not constitute all that is included under that name. See all the above terms.
