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. ruber on the basis of its narrowly lorate leaf morphology

Funding Information:
We thank Oscar de Viveroscar for the photographs that he forwarded to the first author, which first alerted us to the existence of C. inflatus, as well as for the photograph of Clinanthus ruber. Norton Cuba Melly of Lima provided much useful discussion regarding the correct identification of Clinanthus coccineus, and allowed us the use of his photograph of that species. We are grateful to Klei Sousa for his excellent drawings of the new species, rendered quickly and with limited material at his disposal. We also thank Rafael Felipe de Almeida and Ronell R Klopper for their careful reading of two previous versions of this paper. Asuncíon Cano is very grateful to Marybel Morales and Enoc Jara for their very nice collections, and Blanca León for support in different stages of this work
