The Royal expedition to Peru and Chile, led by Ruiz and Pav車n, continued for 11 years in the two colonies and was followed by the activities of Tafalla and Manzanilla, who botanized in Peru and Ecuador. Two preliminary accounts of the flora of Peru were published in 1794 and 1798, but only three of the planned eleven volumes and five supplements of the Flora Peruviana et Chilensis were eventually published. The seventh volume, devoted to the Orchids, never saw the light of day. Due to the short descriptions published in 1798, and the dispersal of large parts of Ruiz and Pav車n*s herbarium, the concepts of several of their orchid species remained obscure to modern botanists. These species can now be identified for the first time through the critical study of the unpublished illustrations and manuscripts of the expedition, kept at the Royal Botanical Garden of Madrid (RJB). The results in orchidology of the expedition, with a discussion of the new findings and interpretations, made possible by the study of Ruiz and Pav車n*s orchid iconography, are presented in two contributions. In this first part 每 an introduction 每 notes on the illustrators and their work, as well as on the orchid manuscripts and collections, are given. Orchid taxa are presented alphabetically, from Acianthera to Maxillariella. For each taxon references to the nomenclatural types, synonymy, illustrations and exsiccata prepared during the expedition, as well as to Ruiz*s diaries and the unpublished manuscripts of the expedition*s botanists, are provided. In the absence of any actual specimens referable to the type collections and associated with the protologues, Bletia repanda, Epidendrum cordatum, E. viride, Fernandezia laxa, Maxillaria longipetala, M. ramosa, and M. Triphylla are formally lectotypified with the type illustrations conserved in MA. New combinations are proposed for the basionyms Bletia parviflora, Fernandezia punctata, Humboldtia po lystachya, Maxillaria ramosa, and M. Triphylla.
