Abstract
Bergeria dilatata (Lindley & Hutton) Alvarez-Vazquez & Wagner, a Middle Pennsylvanian lycopsid, is redescribed based on type material from England as well as 586 specimens from the Peñarroya-Belmez-Espiel Coalfield, Cordoba province, southern Spain. The species is characterized by longer than broad, smooth leaf cushions showing false leaf scars, and the presence of perennial, long, entire, single-veined leaves. A complete synonymy is presented and 21 new species (two of them with doubts), previously placed in 6 different genera, have been synonymized. Associated Flemingites-type cones, determined as Flemingites russelianus, yielded in situ spores of the Lagenoisporites rugosus type and microspores of the Microspinosporites type.
