Ticoa

Ticoa is a genus originally assigned to the Cycadales from the Early Cretaceous of Argentina, Chile, and Antarctica. Other authors view this genus as a member of the poliphyletic "seed ferns".
Taxonomy.
The genus was erected by Sergio Archangelsky based on material from the Anfiteatro de Ticó formation.
The genus first comprised two species, "T. harrisii" and "T. magnipinnulata," with "T. lamellata" being described from the Bajo Grande locality in Patagonia, Argentina. The species "T. magallanica" was described from the Springhill formation in Chile. "T. jeffersonii" was described from Hope Bay in Antarctica. "T. lanceolata" was described much later from the Anfiteatro de Ticó formation . 
Description.
"Ticoa" includes large, bipinnate or tripinnate leaves with pecopteroid pinnules and a robust rachis. The cuticle, either hypostomatous or amphistomatous, presents large stomata sunken in a pit formed by multiple subsidiary and encircling cells.
