Fossil Plants VOLUME - II

Viac o knihe

I regret that pressure of other work has prevented the completion of Volume 1. Had Volume 2 been written ten years ago, the discoveries made in the course of the last decade would have given an out-of-date character to much of the subject-matter. It is more especially in regard to the Ferns and the extinct members of the Gymnosperms that our outlook has been materially altered by recent contributions to Palaeobotany.
