A new species of genus Bipinnula (Orchidaceae) for Chile

A new species Bipinnula gabriel (Orchidaceae) is described and illustrated. The new species inhabits the coastal sclerophyllous forest of Central Chile, in the locality of Putu, Constitucion, Maule Region. We discussed its identity against two related taxa (Bipinnula plumosa var. plumosa and Bipinnula plumosa var. philipporum) and the differences in terms of their ecological niches. The results showed that the new species has remarkable morphological differences with closest species, in addition to ecological differences supporting this species as new. We described the new species and habitat along with approach for their conservation status and the key for proper determination.
