PREFACE.

This catalogue presents a complete list of the species of the
Bryophytes and Pteridophytes of Pennsylvania, so far as they ©
have come to the notice of the author. Nearly all the speci-
mens cited are either in the herbarium of Lafayette College,
Easton, Pa., or are preserved in other collections where they
have been examined by the author.

The foundation of the list of Bryophytes was an enumera-
tion of the species prepared by the late Mr. Thomas P. James,
of Cambridge, Massachusetts, which together with a mounted
series of the species named, and duplicates from a large number
of stations, he presented to the herbarium of Lafayette College.
All of the specimens just referred to were afterward critically
examined by Mr. Coe F. Austin, who himself enriched the orig-
inal set by his own contributions. Many species since discov-
ered within the bounds of the State have been added.

The catalogue owes much of its enlargement also to the
labors of Dr. A. P. Garber and of Mr. D. A. Burnett, and to the
kindness of Mrs. N. L. Britton, of Messrs. Francis Wolle and
Eugene A. Rau, and of Dr. John K. Small.

This volume is to be followed by another which will con-
tain the Spermatophytes or flowering plants of the State, both
the native species and those introduced and growing beyond
culture. TuHos. C. PORTER

Easton, Pa.

NOTE.

At the request of Dr. S. A. Martin, executor of Professor
Porter’s estate, the undersigned has consented to edit this cata-
logue and that of the higher plants of the State referred to in a
preceding paragraph.
