Abstract

The impression species Sphenophyllum incisum Wagner is fully described for the first time. with due reference to intra-specific variation as shown by abundant material from a single locality in the Stephanian B of North-west Spain. The associated strobilus is also recorded. Sphenophyllum nageli Grand'Eury, a middle to late Cantabrian species, is redescribed from the type region in the Cevennes, southern France. Similar material is illustrated from Cantabrian and Stephanian A localities in North-west Spain. Brief comments are made on several other species of Sphenophyllum from the Stephanian of western Europe, and a range chart is provided.
