FORGESIA curvata gen. et sp. nov. is described from the Lower Devonian (Early Emsian) of Marchin (northern margin of Dinant Synclinorium, Belgium). Only a few specimens of this new taxon are known, but it is, however, easily recognizable: the sporangia are rounded to slightly reniform and borne at the end of very long stalks. These are abaxially curved, with an angle of more or less 270.degree. This character is enough to distinguish Forgesia curvata from all the other Lower Devonian plants previously described. The spores and the anatomy of the plant are unknown. Nevertheless, Forgesia curvata is tentatively assigned to the Zosterophyllales because of the lateral position and reniform shape of its sporangia.
