Lower Cretaceous Angiosperms [PDF]
IN the course of my work at the British Museum on Cretaceous plants, I have examined a number of more or less perfectly petrified “woods.” Such specimens have generally been classed together as “Gymnosperms,” so that they have received little attention from palaeobotanists. As I am undertaking an exhaustive study of the Cretaceous plants, the keeper of
