Tepin

''Capsicum annuum'' var. ''glabriusculum'' is a variety of ''Capsicum annuum'' that is native to southern North America and northern South America. Common names include chiltepín, Indian pepper, chiltepe, and chile tepín, as well as turkey, bird’s eye, or simply bird peppers, due to their consumption and spread by wild birds, "unlike humans birds are impervious to the heat of peppers". ''Tepín'' 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 with tepin, although the tepin fruit is round to oval where as the pequin's fruit is oval with a point, and the leaves, stems and plant structures are very different on each plant.

Description

Chiltepin is a perennial shrub that usually grows to a height of around , but sometimes reaches . In areas without hard frost in winter, plants can live 35–50 years.

The tiny chili peppers of ''C. a.'' var. ''glabriusculum'' are red to orange-red, usually slightly ellipsoidal, and about in diameter. Some strains of tepin peppers are much closer to perfectly round when fresh. A tried tepin pepper appears quite round even if it was slightly ellipsoidal when fresh. Tepin peppers are very hot, in Scoville Heat Units (SHU) measuring between 465,000–1,629,000, or 325,000–2,469,000 depending on the capsaicinoid ⇨ SHU conversion method.

The tepin can be hotter than the habanero or red savina, with the highest levels seen in green fruit 40-50 days after fruit set.

However and since this pepper is primarily harvested from wild stands in the Mexican desert, the heat level of the fruit can vary greatly from year to year, depending on the amount of natural rainfall that occurs during the time the fruits are forming. Fruit heat levels can be weak during drought years, and normal rainfall years produce the highest heat levels. The heat levels also varies between the green fresh fruits (which are pickled in vinegar), red-ripe fresh fruits, dried whole fruit, and dried fruit with the seeds removed, with heat levels arranged from mildest to hottest in that order. Around 50 tons are estimated to be harvested commercially annually in Mexico, primarily in Sonora.

In Mexico, the heat of the chiltepin is called ''arrebatado'' ("rapid" or "violent"), because, while the heat is intense, it is not very enduring. This stands in contrast to the domesticated 'Pequin' variety, which is the same size as the wild tepin, but is oval-shaped, and delivers a decidedly different experience.

The different drying methods used for the tepin and 'Pequin', can help tell these peppers apart. Tepins are always sun-dried, whereas the Pequins are commonly dried over wood smoke, and the smell of the smoke in the Pequins can help separate the two varieties. Pequins are not as hot as chiltepins (only about 30,000–50,000 Scoville units), but they have a much slower and longer-lasting effect.

Habitat and range

''C. a.'' var. ''glabriusculum'' can be found in Texas, Arizona, and Florida in the Southern United States, the Bahamas, the Caribbean, Mexico, Central America, and Colombia. It prefers well-drained soils, such as silty or sandy loams, and of annual precipitation in Puerto Rico. It may be found in areas with a broken forest canopy or disturbed areas that lack tree cover if moisture and soil are favorable. Elsewhere, such as in Arizona, it may require the partial shading of a nurse plant.

Symbolism

Chiltepin was named "the official native pepper of Texas" in 1997, two years after the jalapeño became the official pepper of Texas.

Conservation

In 1999, Native Seeds/SEARCH and the United States Forest Service established the Wild Chile Botanical Area in the Coronado National Forest. Located in the Rock Corral Canyon near Tumacacori, Arizona, the preserve protects a large ''C. a.'' var. ''glabriusculum'' population for study and as a genetic reserve.
