Notes on some petrified cones of the Pinaceae from the Cretaceous

References are made to five species of Pinaceous cones from the Cretaceous. The general morphology of the first three was described by Fliche in 1896. Detailed studies on their anatomy have now enabled revisions to be made in their taxonomy. Pinus argonnensis Fliche has been shown to be indistinguishable from Pityostrobus soigniesiensis Alvin, described in 1960. Tsugites magnus Fliche and Pinus praemonticola Fliche are specimens of a previously named species, Pityostrobus andraei (Coemans) Seward, and their names have been included in its synonymy. A note on Pityostrobus leckenbyi (Lindley and Hutton) Seward attempts to clarify a few points on its anatomy and taxonomy. Finally the discovery of an additional specimen of Pityostrobus jacksonii Creber is recorded and some details of this specimen are given.
