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