The foregoing include two fungi, two ferns, thirteen gymnosperms 

 and six angiosperms, and are of unusual interest in being based upon 

 anatomical material. Xo plants preserved as impressions have been 

 described from this region, although it would seem certain that a near- 

 shore shale, at least at some horizons, would abound in remains from the 

 nearby land.
