'''''Capsicum annuum'' var.

However and since this pepper is primarily harvested from wild stands in the Mexican desert,<ref name="Sanatombi"/> 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 hottest to mildest in that order. Around 50 tons are estimated to be harvested commercially annually in Mexico, primarily in Sonora.<ref name="Sanatombi">{{cite journal | issue=2 | volume=36 | last2=Sharma | pages=89–90 | date=2008-12-30 | journal=Notulae Botanicae Horti Agrobotanici Cluj-Napoca | issn=1842-4309 | first1=K. | first2=G.

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),<ref>{{cite web |url=http://homecooking.about.com/library/weekly/blhotchiles.htm |title=Chile Pepper Heat Scoville Scale |work=Home Cooking |publisher=About.com |access-date=2010-07-16 |archive-date=2012-02-26 |archive-url=https://web.archive.org/web/20120226211137/http://homecooking.about.com/library/weekly/blhotchiles.htm |url-status=dead }}</ref> but they have a much slower and longer-lasting effect.
== Habitat and range ==
''C. annuum'' var. ''glabriusculum'' is native to the Sonoran-Arizonan desert and can be found in Texas, Arizona, Louisiana and Florida in the Southern United States, the Bahamas, the Caribbean, Mexico, Central America, and Colombia.<ref name="GRIN"/> It prefers well-drained soils, such as silty or sandy loams, and {{convert|800|-|2000|mm|in|abbr=on}} 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.<ref name="IITF"/>
