Flora Huayaquilensis is the popular name for the body of work produced by the botanist Juan José Tafalla during his time in South America.
Juan José Tafalla Navascués made one of the first expeditions to South America by a Spaniard that documented plants of South America. His unpublished works had been in the archives for 200 years. 
Dr. Eduardo Estrella was working and researching in the archives of the Royal Botanical Gardens in Madrid Spain in 1985 when he found the documentary of the "Fourth Division," for the expedition of Ruiz and Pavon in Peru and Chile, Dr. Estrella found a large number of descriptions of plants whose origin corresponds to the places that belong to the Royal Audience of Quito.
The folios were numbered and contained the mysterious initials FH and those of others that do not correspond to the flora of the Royal Court and had the initials FP was not yet clear, but there was insufficient evidence to believe that was the track of something important and this leaves the publication of the flora and Huayaquilensis after 200 years, finally publishing the hard work and giving credit to the expedition of Juan José Tafalla Navascués. The Botanical Expedition to the Viceroyalty of Peru was very similar to the expedition of Juan José Tafalla Navascués. Dr. Eduardo Estrella Aguirre also founded the Ecuador National Museum of Medicine.  
Not all early explorers of Ecuador were so lucky in having there documents survive. Theodor Wolf (February 13, 1841 - June 22, 1924) was a German naturalist who studied the Galápagos Islands during the late nineteenth century. Wolf Island (Wenman Island) is named after him. Wolf had performed a geologic survey of mainland Ecuador, but unfortunately his collections were lost in storage.
