Richard Evans Schultes has no doubt been one of the most important ethnobotanists of the 20th century. During decades of fieldwork, first in Mexico and then the Colombian Amazon, Schultes amassed a wealth of data later presented to the public in over 400 papers and dozens of books. Much of this work would, however, not have been possible without dedicated counterparts and students. You hold now in your hands the proceedings of the first symposium to honor Richard Schultes, which took place in St. Louis, Missouri, on the 10th anniversary of his death.
