There is also a paper by Daniel Oliver, 'Descriptions of New Species of Utricularia from South America, 1859 (pp 169-176). Mark Honigsbaum in his book Valverde's Gold, 2004, on the exploration in eastern Ecuador for Incan gold, refers extensively to Spruce's work, especially that on Llanganati Mountains and he reproduced Spruce's map described above in his book but in much reduced size. The manuscript notes in parts of this work may be in Spruce's hand but this is not verified. Spruce was one of the great plant hunters of the Amazon region, collecting over seven thousand botanical specimens, many of which were previously unknown. Spruce was in the Amazon region at the same time as Bates and Wallace, and all three lived on the earnings from specimens sent back to England. In 1860, Spruce collected some 600 cinchona plants and thousands of seeds in Ecuador for raising in India for the production of quinine as a cure for malaria. The Royal Geographical Society elected him an honorary fellow in 1866 for his fine work. The Linnaean Society also made him an associate. Spruce was a great influence on the work of Darwin, Wallace, Richard Schultes and others. The author's 'Notes of a Botanist on the Amazon & Andes; being records of travel on the Amazon and its Tributaries, the Trombeta, Rio Negro, Uapes, etc. . to the Orinoco, the eastern side of the Andes of Peru and Ecuador and the shores of the Pacific during 1849-1864' was published in 1908 after his death, by Alfred Russell Wallace, and remains a classic work of travels in South America and especially Amazonia.
