Critical notes on Draconanthes aberrans (Orchidaceae, Pleurothallidinae) with description of new species

Abstract

The actual variation and specific diversity of Neotropical Draconanthes aberrans is evaluated based on morphological data. Asrecognized in this paper D. aberrans complex includes a total of 6 species, 3 of which are described here. New combinations are proposedfor Lepanthes prionota and L. trachysepala. Two species, including D. aberrans, are lectotypified. The previous incorrect typificationsare discussed. Each of 6 species is morphologically characterized. The perianth segments of all discussed taxa are illustrated. The keyto identification of species belonging to the Draconanthes aberrans complex is presented together with the comparative morphology ofstudied taxa.
