Voltz (1785-1840), a French mining engineer.] The generic name given by Brongniart (1828) to a fo il plant which first appeared in the Permian, and found also, in several localities, in the various divisions of the European Trias, and in rocks of the same age in India. Voltzia belongs to the Coniferæ, and is placed by Schenk among the Taxodineæ. It is a tree of considerable height, resembling Araucaria in general appearance, but having a fructification analogous to that of the Taxodineæ. The fo ils called Cyclopteris Liebeana by Geinitz are considered by Kidston as being. in all probability, the bracts of a cone of Voltzia. The Glyptolepis of Schimper and the Glyptolepidium of Heer were also (in 1884) placed by Schenk under Voltzia.
