Popis:	A new arthrophyte species, Pseudobornia schweitzeri Jurina et O. Orlova, sp. nov., from the Upper Devonian of northern Timan (northern European Russia) is described based on its peculiar leaf structure and anatomical features of stems and axes. The structure of the main stem and lateral axes, characters of the stem ribs and nodal curves, and leaf morphology are considered in detail. The presence of only conductive elements of the primary xylem in the axes of different orders of P. schweitzeri Jurina et O. Orlova, sp. nov. is shown. This is indicative of the absence of secondary growth of this plant. The systematic position and generic and species criteria of Pseudobornia are discussed.
