A new species and a new combination in Stelis (Pleurothallidinae-Orchidaceae) from South America

Abstract

Stelis duckei, of the Crocodeilanthe group, is described from the state of Ceará, Brazil. The new species is morphologically similar to S. speciosa, but can be distinguished by its longer ramicauls, wider leaves, and obtuse lip with a ridge-like callus at the base. The new combination Stelis speciosa is also provided here.
