To the State Botanist, Dr. Charles H. Peck, who has kindly read the proof-sheets of this book, I am indebted for many suggestions; also to Mr. Arthur G. Clement, of the University of the State of New York.
To Miss Marion Satterlee thanks are due not only for many suggestions, but also for the descriptions of the Woodwardias.
The pen-and-ink illustrations are all from original drawings by Miss Satterlee and Miss Alice Josephine Smith. The photographs have been furnished by Miss Murray Ledyard, Miss Madeline Smith, and Mr. Augustus Pruyn.
In almost all cases I have followed the nomenclature of Gray's "Manual" as being the one which would be familiar to the majority of my readers, giving in parentheses that used in the "Illustrated Flora" of Messrs. Britton and Brown.
