The species to which it belongs was originally described by Dr. Linpey, in 
his Genera and Species of Orchidaceous Plants, in 1840, as Cypripedium caudatum, his 
materials being a simple flower from the Herbarium of Ruiz and Pavon, sent 
by Marruews to Sir Witiiam Hooker. Thus we have direct evidence that the 
plant was discovered by the Spanish botanists Ruiz and Pavon during their 
exploration of Peru and Chili in 1778 to 178g, and probably in the Huanuco 
district in Peru, which they visited. Six years later the same author described 
the so-called genus Uropedium in his Orchidaceae Lindenianae, from a plant 
collected by M. J. Liven in June 1843. He described it as having all the 
characters of Cypripedium except that the lip was flat, the petals prolonged into
