PREFACE.
T he first volume of this work having been at length completed,
the authors have to perform the pleasing duty of offering
their acknowledgments to their numerous friends and correspondents
who have rendered important assistance to their
arduous undertaking.
To Sir W illiam H ooker, than whom perhaps no person has
done more for the advancement of North American Botany, we
are largely indebted, not only for the opportunity of consulting
his rich herbarium and excellent library under the most
favorable circumstances, on two different occasions, but for the
generous communication of a great number of authentic specimens
of the plants described in the Flora Boreali-Americana, the
Botany of Capt. Beechey’s Voyage, and other works, selected
from the collections made in the Northern land expeditions of
Capt. Sir John Franklin, those of the Arctic voyages of discovery,
and especially from those made in Oregon, the Rocky Mountains,
&c. by the late Mr. Drummond, the late indefatigable Douglas,
Mr. Tolmie, and others. To Dr. Richardson we are directly
indebted for many plants collected by himself in Capt. Franklin’s
first expedition to the shores of the Arctic S e a ; and to Dr. now
Professor Scouler, for a collection of Oregonplants.
To Mr. Brown our acknowledgments are due for the unrestrained
opportunity of consulting the Banksian herbarium, as
well as the herbaria of Clayton, Catesby, Plukenet, and the other
collections in his charge at the British Museum ; and to Mr.
Bennett, the Assistant Curator, and Secretary of the Linneean
