now lost, making Thiselton-Dyer's copies a uniquely valuable resource on Rodrigues's work. In 1875, Rodrigues published Enumeratio Palmarum Novarum, describing a number of new palm taxa. In subsequent years, an English botanist who had met Rodrigues in Brazil, James William Helenus Trail, published some of the same species and even claimed precedence over Rodrigues. Despite this dispute over primacy, which lasted for many years, in 1903, Rodrigues published a classic work on palms, Setum Palmarum Brasiliensis. This was a survey of over 380 species of palms, 166 of which were newly described. Financed by the Brazilian government, it was printed in Belgium and lavishly illustrated with some 170 of Rodrigues's watercolors. After the Amazon expedition of the 1870s, Rodrigues became discouraged over the difficulty of funding another expedition and briefly detoured into business, running a chemical factory. Not long afterwards, he was tasked to organize and direct a brand-new Botanic Museum of the Amazon in Manaus, which opened in 1883 under the sponsorship of Princess Isabel. He founded a journal, Vellosia (named in honor of José Mariano de Conceição Vellozo), to showcase the museum's work; it was discontinued after only four volumes were issued. Despite its royal patronage, the museum struggled financially and closed in 1890 when Rodrigues moved on to become director of the Botanic Garden of Rio de Janeiro, a position he would hold until his death. At the height of its development, the Botanic Museum of the Amazon had held some 10,000 botanical specimens, nearly all of which were lost on the museum's closure. During his directorship of the Rio de Janeiro botanic garden, Rodrigues constructed a greenhouse and library, diverted the Monkey River (whose waters tended to flood the garden), opened and landscaped new areas of the garden, planted an arboretum, considerably increased the size of the live plant collection, and took steps towards organizing a herbarium. He started a journal to publish the botanic garden's scientific work, the Contributions du Jardin Botanique du Rio de Janeiro. Rodrigues died on March 6, 1909. Personal life Rodrigues married at the age of 20 but soon lost his wife to tuberculosis. He married again a few years later and once again was quickly widowed, this time being left with a small daughter. His third marriage, to Constança Pacca, lasted many years and produced seven more daughters and six sons. He named the orchid genus Constantia after her. Legacy
