Resumen

A new species of the genus Hippeastrum (Amaryllidaceae, Amaryllidoideae, Hippeastreae), collected at Escoipe area (Salta, Argentina), is here described as H. escoipense. Due to its morphological affinities, it was erroneously considered under the binomial H. argentinum, a species from which it differs by its three-lobed stigma and erect leaves (vs. trifid stigma, curved leaves). We provide information on geographic location, habitat description, conservation status assessment, along with a key to differentiate it from related species from Argentina and Bolivia, and the comparative chemical profile of alkaloids between this new entity and H. argentinum.
