Frenguellia a new genus of lycopods from the Early Carboniferous of Argentina

Impressions of small lycophyte stems, Frenguellia gen. nov., are described from Early Carboniferous sequences of Argentina. Its leaves are five parted with an elongate central division and two opposite divided lateral divisions. They invite comparison with Leclercqia Banks, Bonamo et Grierson. The l...
