Abstract
The type material of some fossil Pinaceous cones (from the Albian of France) originally described by Fliche in 1896 under the name Pseudoaraucaria is here redescribed in detail. The cones are similar in form to one from the English Lower Greensand hitherto called Pityostrobus benstedi (Mantell) Seward which is also redescribed here. This newly recognized group of cones differs from the cones of any of the recent members of the Pinaceae chiefly by (a) the massive ridge of scale tissue lying between the seeds so that these are deeply embedded in the basal part of the scale, and (b) the presence of a cushion of parenchyma at the chalazal end of the seed. The probable significance of these and certain other characters is discussed.This publication has 0 references indexed in Scilit:
