The Juniperus Coahuilensis is commonly known as the Redberry Juniper as well as Rose-fruited Juniper.

The currently accepted scientific name for redberry juniper is Juniperus coahuilensis (Martinez) Gaussen . Confusion about the correct name for this entity arose over its morphological resemblance to oneseed juniper (J. monosperma) and over its red cones, which resemble those of Pinchot juniper (J. pinchottii). Redberry juniper intergrades with Pinchot juniper in the Trans-Pecos region of Texas, where their ranges overlap. There is a probable hybrid swarm in the Basin of the Chisos Mountains, Texas . Zanoni and Adams determined that redberry juniper and Pinchot juniper are the most closely related junipers based on similarity of leaf oil terpenoids and other characters.

Redberry juniper occurs in disjunct populations from western Texas (Trans-Pecos), southwestern New Mexico, and southern Arizona south to San Luis Potosi, Mexico .

In the Southwest junipers (Juniperus spp.) are associated with oaks (Quercus spp.) and true pinyon (Pinus edulis). Junipers increase in dominance over oaks and pinyons on dry sites . Redberry juniper is common in alligator juniper (J. deppeana)-pinyon woodlands and savannas, and in areas where its range overlaps with Utah juniper (J. osteosperma), oneseed juniper (J. monosperma), and Rocky Mountain juniper (J. scopulorum) . It occurs in evergreen oak woodlands with Emory oak (Q. emoryi) and Mexican blue oak (Q. oblongifolia) . Redberry juniper is also found in Arizona chaparral woodlands with shrub live oak (Q. turbinella) and Arizona rosewood (Vauquelinia californica) . It occurs as scattered individuals in grama (Bouteloua spp.) grasslands, along with scattered velvet mesquite (Prosopis velutina), Mexican blue oak, and alligator juniper . A publication listing redberry juniper as a codominant species is as follows: Classification of pinyon-juniper (p-j) sites on National Forests in the Southwest
