| Resumo |
A new species of Pelexia Poit. ex Until. (Orchidaceae, Spiranthinae) occurring in central Sao Paulo, southeastern Brazil, is described and illustrated as P. vinosa A. W. C. Ferreira, M. I. S. Lima & Pansarin. Pelexia vinosa is recognized by its leaves that are present at flowering and its dark purple leaf blades with reddish margins. Inflorescences are sparsely pubescent and reddish. The red sepals contrast with the white hyaline petals and labellum. The species is notable for its spurlike nectary that is parallel and adnate to the ovary. The new species is morphologically similar to P. laxa (Poepp. & Endl.) Lindl. In addition, the need to preserve native areas of the interior of Sao Paulo State (habitat of P. vinosa) is discussed.
