Capsicum annuum var. glabriusculum is a variety of Capsicum annuum that is native to southern North America and northern South America. Common names include chiltepin, Indian pepper, chiltepe, and chile tepin, as well as turkey, bird’s eye, or simply bird peppers, due to their consumption and spread by wild birds. Tepin is derived from a Nahuatl word meaning "flea". This variety is the most likely progenitor of the domesticated C. annuum var. annuum. Another similar-sized pepper 'Pequin' (also called 'Piquin') is often confused, the Tepin fruit is round to oval and the Pequin is oval with a point, and the leaves, stems and plant structure are very different on each plant.
