A new small-flowered cyrtochilum species (Orchidaceae: Oncidiinae) from the condor mountains in Ecuador

Abstract

A new small-flowered species of Cyrtochilum from the isolated range of the Condor mountains in Ecuador is described and illustrated with a line drawing and a photograph of the holotype. It shares morphological features with several different-looking groups of Cyrtochilum, such as the two generitypes of the genus: C. undulatum and C. flexuosum, as well as with plants in the C. myanthum complex. These groups are treated as three separate genera by some (Cyrtochilum, Trigonochilum and Dasyglossum, respectively), but the combination of morphological features seen in our new species brings the groups together into one polymorphic but genetically monophyletic genus.
