The authors venture to hope that their obliging correspondents
will still continue to render their assistance in the farther prosecution
of this- work, by sending the rarer plants of the.r respective
districts, with such notes and observations as they may
deem important.
Since the publication of the earlier portions of this volume, our
opportunities for examining the herbaria of original authors have
been very much extended ; and the necessary corrections and
changes we have been obliged to make on this account, together
with some additions from works recently published and from
materials since received, are given in the appended Supplement.
We trust these investigations will give this work an important
value in respect to the authenticity of the specific names, and that
future changes of the kind will not be to any considerable extent
necessary.
