342 HanniBpaL: A PLIOCENE FLORA FROM CALIFORNIA 
ACKNOWLEDGMENTS 
Acknowledgments are due first of all to Dr. J. P. Smith, at 
whose suggestion this study was undertaken, and whose interest 
and ever ready criticisms have made results possible. Dr. W.R 
Dudley and Dr. LeRoy Abrams have permitted the free use of 
the Stanford University Herbarium, assisted in making identifica- 
tions, and contributed everything in their power toward the 
writer’s interest. Mr. James McMurphy, from his familiarity 
with the flora of the northern Coast Ranges, has also been of 
material assistance in the matter of determination of material. 
The plate is reproduced from photographs taken by Mr. John 
Howard Paine.
