a portion of the plants collected during his t iw j s jn Arkansas

Our acknowledgments are also due to the Baonjca] c om_
mittee of the Academy of Natural Sciences, Njladelphia
who have obligingly afforded us every facility in cons^;n„
large herbarium of that Society, which includes that of th. ]a^e
Mr. Yon Schweinitz, and the chief collections of Mr. Nuttqi
To the urbanity of Mr. Vaughan, the Librarian of the AmenV
can Philosophical Society, we are indebted for the opportunity
of examining the botanical collections in the custody of that
Society, comprising the herbarium of Muhlenberg, and that of
the late Professor Benjamin Smith Barton, which appears to
have been formed by Pursh, and contains many of his plants.
To the daughter of the lamented E lliott, we desire to
express our thanks for kindly entrusting to our charge a portion
of her late father’s herbarium ; and also to Prof. Bachman and
Prof. Gibbes of Charleston, South Carolina, who kindly selected
and transmitted to us the specimens which we desired.
To Mr. B. D. Greene of Boston, for the loan of a very
complete sot of the plants collected by the late Mr. Drummond
in Texas.
To our numerous correspondents in different parts of the
country, who have from time to time furnished us with valuable
collections and observations, our limits will only allow us to
offer our acknowledgments in general terms. Their names
frequently occur throughout the pages of this work, where we
have endeavored faithfully to indicate the sources from whioh
our specimens have been derived, as fully as the plan of the
work would permit. But whenever a species has been received
from several correspondents, and from different sections of the
country, we are obliged, in most cases, to omit the citation of
particular localities, and to give as nearly as possible its geographical
range. Additional specimens of many rare plants
described in this volume have also been received since the
Orders to which they belong were printed ; and we have only
space to notice the more important of these accessions in the
Supplement, this volume having already extended much beyond
PREFACE. xi
its intended limits. We would therefore, at present, briefly
state, that we are indebted to the following persons, to many of
them very largely, for the plants of particular districts, accompanied
in many instances by valuable notes and observations,
