Plant hunters in the Andes

"The first edition, published in 1941, was based on Goodspeed's first two expeditions to the central Andes, whereas the present edition, reporting on four additional expeditions, has a greatly enlarged horizon extending from Colombia in the north to Cape Horn in the south, west to the Juan Fernandez Islands, and east into Paraguay, Uruguay, and the Argentine, a truly extraordinary range for this kind of meticulous plant exploration." -- Richard Evans Schultes, Economic botany, vol. 17 no. 1
