Abstract

Two new species of Ibatia (Apocynaceae, Asclepiadoideae, Asclepiadae, Gonolobinae) from the Chaco region of the Salta province, Argentina, are described and illustrated: I. dummelii and I. micrantha. Ibatia dummelii was collected in the Chaco Serrano and is distinguished from related species by the reflex perianth; Ibatia micrantha was collected in the Dry Chaco and is characterized by the very small flowers. As a result, the number of species registered for Ibatia in the Argentinian Flora now rises to seven.
