More recently Saporta has published a note in the Comptes 
Rendus for 1891,! in which he mentions some interesting species 
of fossil plants discovered at Cercal, between Cenomanian and 
‘‘ Neojurassic’? beds. Among the ferns he draws attention to 
Sphenopteris Mantelli, Brong., S. plurinervia, Hr., S. valdensis, 
Hr., and 8S. angustiloba, Hr.; there are also two species of 
Hepatice recorded, and two or three Lycopodiaceous plants, with 
a remarkable new species, Jsoetopsis Choffati, referred to the 
Tsoetacee. Brachyphyllum, Sphenolepidium and Frenelopsis are 
quoted as Coniferous genera. 
The most important fossils are, however, certain species which 
he considers to be Angiosperms, and especially Dicotyledons. 
Poacites, Brong., Zosteris, Brong., and Delgadoa, Sap., are placed 
among the Monocotyledons, with Protolemna and Protorrhipsis, 
Andr., as representatives of the oldest known Dicotyledons.
