Abstract

A phylogenetic study of Sobralia (Orchidaceae) confirmed the polyphyletic character of the genus. Sobralia also appears to be highly heteromorphic in the morphology, especially considering the position and architecture of inflorescence, lip form and kind of its outgrowths, length and form of stelidia of column. The infrageneric relationship of Sobralia species was revealed by analyses of three DNA markers (nuclear ITS, xdh and plastid matK). The nominal section of the genus appears to be more related with Elleanthus and other genera of Sobralieae than with the remaining species of Sobralia. Sobralia section Sobralia differs from other representatives of the genus by the position and architecture of inflorescence, smaller floral bracts and the morphology of the flowers. We propose a generic rank to the group despite its paraphyletic nature. Nomenclatural consequences of this proposal are briefly discussed. Appropriate transfers to the newly erected genus Brasolia are proposed. A new species, Brasolia floribunda, previously detected by Reichenbach, but never formally described, is validated. Lectotypes for five species and a neotype for the other one are proposed.
