A series of unfortunate events: the forgotten botanist and the misattribution of a type collection

Abstract

In 1777, Spain sent The Royal Expedition to Peru and Chile, commonly referred to as the “Ruiz and Pavón Expedition”, to document the flora of this richly diverse part of its colonies. The Expedition was active in the New World for 38 years and was led by Hipólito Ruiz and José Pavón, who collected in Peru and Chile for the first 11 years before returning to Spain to work on publication of the Flora Peruviana, et Chilensis. Work on the ground for the reminder of the project in Peru and later Ecuador, was continued by Juan Tafalla and Juan Manzanilla. With few exceptions, all collections from the Expedition including types, have conventionally been attributed to Ruiz and Pavón despite the fact that Tafalla and Manzanilla were responsible for a large part of the collections. The purpose of this note is to bring to light the important but often overlooked figure of Juan Tafalla, to highlight his accomplishments as a collector and to increase precision in botanical nomenclature by giving him due credit by correctly attributing collections.
