Interpretive Summary: We describe two new species from South America that belong to the amaryllis family (Amaryllidaceae), an important group of ornamental flower bulbs. Clinanthus inflatus and Ismene virescens) are both found in the Andes of Peru. We also transfer a mis-diagnosed name, Stenomesson rubrum, into Clinanthus as C. ruber. This contribution clarifies the taxonomy of this highly diverse ornamental family and increases our understanding of its biodiversity in the Americas.

Technical Abstract: Clinanthus inflatus (Amaryllidaceae) and Ismene virescens are described from Ancash Department in Peru. The flower of C. inflatus is urceolate, and resembles that of Urceolina (Eucharideae), a unique morphology for the genus. Ismene virescens, with its loosely formed, narrowly funnelform-tubular perigone with a ventricose limb, appears to have some affinity to subg. Pseudostenomesson and may represent an intermediate form between the former and species of subg. Ismene. Stenomesson rubrum is transferred to Clinanthus as C. ruber.
