Excerpt from Transactions of the National Medical Congress, 1887, Vol. 3: Ninth Session Much of the work has been done by the aid of the Government. Among the most eminent botanists to whom we are indebted for success in this work are Warren Upham, Minnesota Report on Botany; Prof. J M. Coulter, Botany of the Rocky Moun tain Region; Prof. Gray, and Brewer and Watson, in Botany of California and Pacific Region, and Dr. Rothrock, in Report on Botany of Southwestern States and Territories, in Wheeler's Geographical Survey. Prof. Gray's standard works and Chapman's Botany of the Southern States are invaluable to those who wish to examine medical plants. It is well known that many of our medical plants are immigrants, coming to this country from sans the Atlantic in most instances, though we have many introduced from warm southern climes.
