Abstract
Five species and one additional type of spores of Devonian age are included in a new genus, Emphanisporites. All but one of the species of spores described are new. They are characterized by radially disposed thickenings of the proximal wall. The wide geographic extent of spores of this genus, whose parents have not yet been recognized, is evidence of an ubiquitous floral element existing contemporaneously with the so-called "Psilophyton flora". Available evidence restricts the range of Emphanisporites to the Lower and Middle Devonian.Keywords
