摘要

New specimens of the progymnosperm Rellimia are described from the Middle Devonian of Wuppertal, Rhenish Massif. The new material proves that some of the fossils published decades ago and later assigned to Rellimia thomsonii represent a distinct species, Rellimia piedboeufii nov. comb., which differs from R. thomsonii in the general slender appearance, different branching pattern, laterals and anatomy. It is restricted to the Eifelian while the first appearance of R. thomsonii is near the Eifelian-Givetian boundary.
