Copacabana is more than a beach in Rio de Janeiro, Brazil: the orchid flora of Parque Estadual da Chacrinha
Orchidaceae is the most diverse botanical family in the city of Rio de Janeiro, Brazil, with 79 genera and 250 species. Vegetation in Rio de Janeiro is mostly restricted to small fragments of Atlantic Forest, many of which are located within conservation units and act as refuges for flora. Some of the best-known postcards of the city, such as Corcovado and Sugar Loaf mountains, and the Christ the Redeemer statue, are located within rban conservation units. This work presents the results of a floristic-taxonomic study of Orchidaceae in the Parque Estadual da Chacrinha (PE Chacrinha), a state park located extremely near the famous Copacabana beach in the heart of Rio de Janeiro. Brief morphological descriptions of the species are provided and an identification key for the orchids of PE Chacrinha is presented, based mainly on vegetative morphological characters. Orchidaceae of PE Chacrinha is represented by thirteen genera and 16 species, most of which restricted to Brazil, seven of them are also endemic to the Atlantic Forest, or South America and occur as terricolous or rupicolous. We highlighted the occurrences of Acianthera limae, Epidendrum ammophilum and Prescottia spiranthophylla, species that grow exclusively or predominantly on rocky outcrops. With these findings, our goal is to raise awareness among the local population about the importance of conserving the regional flora; estimulate visits to PE Chacrinha and promote the inclusion of this conservation unit in the tourist tinerary of the city of Rio de Janeiro.
