Abstract

SANGUINETTI, Agustín  and  CAMPOS, Hugo. Presence of the orchid Sacoila lanceolata (Orchidoideae: Cranichideae: Spiranthinae) within the limits of the city of Buenos Aires. Bonplandia [online]. 2022, vol.31, n.1, pp.47-54. ISSN 0524-0476.  http://dx.doi.org/10.30972/bon.3115804..

Even though the city of Buenos Aires is an anthropized territory in its entirety, there are vegetation patches that house spontaneously occurring native plants. We report here the occurrence of the terrestrial orchidSacoila lanceolata(Aubl.) Garay within the perimeter of the city. It was found in theArboretumof Parque Sarmiento, a recent enclosure of 1000 m2where native species of Buenos Aires’ riverine region are conserved. This report occurs at the southern limit of the species’ distribution, where other nearby records are more than 200 km away. Given the unexpectedness of this event we discuss the nature of its occurrence and its relevance as a potential flag species.
