Acknowledgements 
Dr. Frank M. Carpenter kindly provided information 
on the known stratigraphic ranges of the families men- 
tioned. Dr. Roland W. Brown identified the fossil leaves 
and made several helpful suggestions and corrections on a 
preliminary copy of this paper. 
It is hoped that this paper will be a tribute to the late 
Dr. R. Lee Collins who recognized the significance of these 
fossils. They have been placed in the collections of the 
United States National Museum where many other excel- 
lent specimens of fossil plants from the Wilcox deposit 
collected by Dr. Collins have previously been placed.
